In Search of Sand: Debris Flows and Pacific Lamprey Habitat, Salmon River, California

Thu, 28 Nov 2024 00:00:00 +0000

The headwaters of Blind Horse Creek originate in the highest point of the Trinity Alps. It is a tributary to the South Fork Salmon River located in the Klamath National Forest. In the summer of 2021, wildfires burned 114,433 acres in the Salmon River watershed. For this subbasin of the greater Klamath River Basin (KRB), this was the greatest number of acres burned in a single year on record. The River Complex was a large-scale, high-severity wildfire that burned all around the South Fork Salmon River leaving steep drainages barren of any vegetation. The following year, 2022, summer rains brought 1-2 inches of rainfall to the landscape and triggered a debris flow within the Blind Horse Creek drainage. Although initially a major disturbance to the river system, over time the new sediment moving through the system deposited behind Large Woody Debris, boulders, and eddies, creating new beaches and sand bars distributed throughout the river. The delivery of fine sediments to streams...

Post-Project Assessment of Step-Pool and Channel Morphology at Wildcat Creek, Tilden Golf Course

Thu, 28 Nov 2024 00:00:00 +0000

In recent years, river restoration has shifted towards natural, process-based approaches rather than fixed, engineered solutions. This new emphasis on natural approaches was implemented in a restoration design and subsequent experiment in the Tilden Park Golf Course reach of Wildcat Creek in Berkeley, California, USA. The restoration design implemented step-pools to address bank erosion and encourage channel stabilization, while the experiment highlighted the creek’s ability to self-organize these desired step-pool formations without the need for human interference. The Restoration and Experimental Reaches were monitored consistently from 2012 to 2017 and again in 2022, and found that after the addition of step-pools, the channel bed remained fairly stable without significant aggradation or erosion. Our study conducted a post-project monitoring of the Restoration and Experimental Reach, to gain further insights on potential changes in the channel and step-pool morphology, as...

Afton Canyon River Restoration Post-Project Appraisal

Thu, 28 Nov 2024 00:00:00 +0000

Vegetation restoration projects throughout the American Southwest have yielded positive outcomes for degraded desert streams, including the Mojave River restoration at Afton Canyon in the Eastern Mojave Desert (Egan, 1999; 2016; Bunn et al., 2003). Although rare, beaver translocation has demonstrated success as a passive desert river restoration strategy at the Price and San Rafael Rivers in eastern Utah and the San Pedro River in Arizona (Soykan et al., 2009; Doden, 2021; Sandbach, 2023). The success of translocated beaver populations is determined by mortality rate and site fidelity, as dictated by habitat quality (Colleen & Gibson, 2000; McKinstry & Anderson, 2002; Petro et al., 2015; Morris et al., 2021; Bilby & Moseby, 2023). In deserts, beaver habitat is restricted to riparian forests (Rutherford, 1964; Bee et al., 1981; Welch et al., 1993). The restoration project at Afton Canyon has facilitated the return of native willow and cottonwood populations and beaver...

Restoration Impacts on Lobos Creek: San Francisco's Last Free-Flowing, Perennial, and Unculverted Creek

Thu, 28 Nov 2024 00:00:00 +0000

In 1996, the National Park Service (NPS) restored a 100-yard section of Lobos Creek in San Francisco. In this study, we evaluated the presence of invasive species within the Lobos Creek restoration project. The restoration site is not actively managed by any organization or volunteer group. Our research is unique in that it is a comparison between an unmanaged restoration site and an actively managed area along the same creek. Our project takes into account the historical land use changes within the area to provide context on how plant communities have been impacted. We found that the unmanaged Lobos Creek restoration site has reduced the presence of invasive species, in comparison to the managed and unrestored upstream portions of the creek.

Establishing a Baseline Surveying of Ackerman Creek (Ya-mo-bida) at Pinoleville Pomo Nation

Thu, 28 Nov 2024 00:00:00 +0000

We researched indigenous-led river restoration in order to understand how this approach promotes long-term stewardship, a common challenge in the river restoration field. We were connected through the UC Berkeley community to the Pinoleville Pomo Nation in Mendocino County. We visited the Pinoleville Pomo Nation (PPN) to learn more about the restoration work they are conducting around Ackerman Creek, a tributary of the Russian River. They are incorporating cultural practices, long term monitoring, continuous maintenance, community outreach, invasive species mitigation, and native plantings into the restoration process. We then conducted a baseline survey of cross-sections and sketches, which may serve as a point of reference for gauging the impacts of future restoration activities. We learned that constraints to this stewardship approach come from limited jurisdiction of the tribe throughout the watershed, resulting in impacts from off-site factors such as dams and runoff. Even...

Social Connectivity to the American River Parkway

Thu, 28 Nov 2024 00:00:00 +0000

The current interest in "multibenefit projects" that balance ecology, flood control, and social use in urban rivers makes developing sound theory and methods for social assessments of urban rivers a pressing concern. "Social connectivity" is one theoretical approach to assessing the relationship between the social use and physical condition of rivers. In this study we apply a social connectivity analysis to the American River Parkway in Sacramento, California. We combined observations of channel form with in person counts of users and activities, interviews with users, and reviews of planning documents to conduct a post project assessment of some of the major goals and use assumptions that informed the planning of the Parkway. We found that channel form and access to the river largely drove use patterns, many uses were quotidian and conventional but the largest user groups were there for special occasions, and that users viewed the Parkway positively but had low awareness of flood...

Long-term fluctuations in sediment composition post San Clemente Dam removal on the Carmel River, California

Thu, 28 Nov 2024 00:00:00 +0000

The San Clemente Dam on the Carmel River was removed in 2015 . We analyzed the grain size distribution changes on the river on one site upstream and six sites downstream of the damsite, as part of an ongoing study monitoring a total of 10 sites since 2013 (East et al., 2023). Trends from this data indicate that the geomorphic changes observed downstream of the dam are predominantly dependent on high flows. This study contributes to field data collection and analyzes fresh pebble count data for 2023 from one control reach above the dam removal and six reaches downstream of the removal. Given that the Carmel River had a peak flow of 11,000 CFS during the 2022-2023 winter, pebble counts from 2023 offer the opportunity to continue studying the stream system’s geomorphic response to high flows. To study spawning gravel availability, we applied the criteria of Smith et al (2021), who used grains within 32mm and 90mm to study spawning gravel abundance, then calculated the average percent...

Strawberry Creek Restoration: Advancing Stewardship in the North Fork

Thu, 28 Nov 2024 00:00:00 +0000

This paper presents historical overviews and original ecological surveys on the North Fork of Strawberry Creek in Berkeley, California to better inform the Kingman Hall Creek Restoration Project. Analysis of geomorphologic changes in the North Fork of Strawberry Creek during urbanization reveals the legacy of alterations on contemporary ecology. Case studies varying in time, scale, and approach contextualize restoration efforts in the entire Strawberry Creek Watershed. The impacts of urbanization and culverting are evidenced by an ecological snapshot of current creek conditions between LBNL and the UC Berkeley Campus. Rod and level topographic surveys, ArcGIS permeability analysis, vegetation analysis, avian surveys, and macroinvertebrate counts conducted at three distinct locations along the North Fork provide a multipronged baseline survey of current conditions. Topographic surveys show a higher degree of incision below culverted stream sections. ArcGIS permeability analysis...

Post-breach Monitoring of a Natural Beaver Dam on French Creek

Thu, 28 Nov 2024 00:00:00 +0000

Our post-project monitoring research focuses on a natural beaver dam on French Creek in the Scott River Watershed in Siskiyou County, CA. The dam exists on a stretch of the creek with several beaver dam analogues (BDAs), which have been implemented by the Scott River Watershed Council in the hopes of combatting incision in the system and recruiting beaver to maintain the structures. French Creek in particular is an important spawning ground for the threatened coho salmon, so the impacts of the dam on fine sediment are of particular interest. Since the installment of the BDAs on French Creek, a beaver family has colonized the site and built a natural beaver dam. In 2021, high flows led to a breach in this dam. Scott River Watershed Council (Council) developed plans to fortify it using similar techniques used in the nearby BDAs. These plans will be implemented in November 2023, one week after this survey.

This dam breach presented the unique opportunity to analyze the surrounding...

Assessing Current Site Conditions and Vulnerabilities to Sea-Level Rise and Saltwater Intrusion: Lower Carneros Creek, Elkhorn Slough

Thu, 28 Nov 2024 00:00:00 +0000

Sea-level rise will have extreme impacts on coastal estuaries, including freshwater sources like rivers and creeks. Though freshwater linkages are critical to overall estuarine health, few studies have explicitly considered how sea-level rise and saltwater intrusion will impact riparian vegetation composition or community health in freshwater creeks adjacent to tidally influenced systems. Our study sought to identify the historical and current conditions as well as projected vulnerabilities for the lower section of Carneros Creek, the main freshwater source for the Elkhorn Slough, in Monterey County, California. To describe historical and current conditions of Lower Carneros Creek, we assessed historical maps, surveyed riparian vegetation using the rapid assessment method, and evaluated drinking water well data for evidence of existing saltwater intrusion. To assess future sea-level rise impacts for Lower Carneros Creek, we mapped previously modeled groundwater rise and saltwater...

Restoring Social Connection to the Salinas River: For Who, Where, and How?

Thu, 28 Nov 2024 00:00:00 +0000

River restoration projects can be designed to cultivate a diversity of human interactions with the riverscape, alongside the fulfillment of traditional biophysical objectives. The Salinas River is a major river in an agricultural valley in California, where restoration projects could address annual concerns of winter flooding while facilitating more human interactions throughout the riverscape. We conducted a study to investigate (i) who currently interacts with the river, (ii) where the sites of these interactions are, and (iii) how we can restore them for ecological and socio-cultural benefits. We combined site visits and evaluations, informal interviews, and GIS analyses to answer our questions. We find the Salinas River largely disconnected from public life, out of view and physical access. Nonetheless, there is a desire to connect with the water and riverfronts. Among the five sites we evaluated, Arroyo Seco is a well-frequented public area with amenities and ease of access...

A Feasibility Study of the Hangzhou Tangxi Canal Restoration

Fri, 13 Oct 2023 00:00:00 +0000

I provide this feasibility study for the future restoration of Tangxi Canal (Hangzhou, Zhejiang, China) to explore whether the canal district can become a social-interactive urban space with healthy environmental conditions and sustained connectivity with the canal waters. Overall, the Tangxi Canal District faces two challenges: first, pollution from fuel leaks from motorboats and stormwater runoff; and second, a lack of sociocultural interaction between residents and the canal. Therefore, the restoration of the Tangxi Canal area requires the following: (a) providing more green spaces and public spaces; (b) addressing environmental problems; and (c) providing more urban amenities.

Sausal Creek Restoration at Dimond Park: Vegetation and Geomorphology Post-Project Appraisal

Fri, 13 Oct 2023 00:00:00 +0000

We conducted a post-project appraisal in November 2022 to evaluate the restoration’s performance using the goals outlined in the Sausal Creek Restoration at Dimond Park Monitoring Plan (Restoration Design Group, Inc. (RDG) 2017): restore native riparian habitat and improve channel stability. We performed vegetation surveys along the three transects (T1, T2, T3) initially defined by RDG and conducted a geomorphic survey along T3. We determined that the restoration project performed well in establishing native riparian habitat as we measured overall >90% canopy cover, which surpasses the percent cover criteria of 75% after five years of project implementation. Furthermore, we observed relatively high shrub survival rates of 138%at T1 and 173% at T2 and a limited shrub survival rate of 35% at T3. Despite meeting overall percent cover and survival rate criteria, we observed a decrease in native flora diversity, potentially due to excessive overstory shading from willows and invasive...

Addressing channel incision through floodplain reconnection: Revisiting the Lower Tassajara Creek project

Fri, 13 Oct 2023 00:00:00 +0000

Actively incising Lower Tassajara Creek in Dublin, California, was restored as a compound channel in 1999-2000 to mitigate incision and provide flood conveyance capacity to reduce flood risk to an adjacent greenfield residential development. The project benefitted from a wide floodplain corridor set aside during development, allowing a rough vegetated overbank channel with a design capacity to carry the 100-year flood. Several years of cross-sectional channel surveys conducted under an informal monitoring program from 2000 to 2006 indicated that active incision was largely attenuated following the restoration, with some minor incision still evident and low-flow channel complexity just beginning to develop. This research evaluates Lower Tassajara Creek 20 years after its restoration, investigating ongoing channel evolution, incision and aggradation, and floodplain reconnection, and discussing channel conditions in the context of the catchment land use history. I repeated and overlayed...

Assessment of the use of grade control for improved groundwater storage on a tributary in Muir Woods

Fri, 13 Oct 2023 00:00:00 +0000

In 2019 grade control modifications were made to a tributary to Redwood Creek in Muir Woods National Monument as a way to evaluate the possible use of check dams to improve groundwater storage. This study seeks to evaluate the effectiveness of the grade control in 1) controlling or reversing incision due to prior land use changes and channel modification and 2) storing groundwater in areas adjacent to the tributary. Our results from initial monitoring efforts suggest that check dams could be effective in inducing aggradation of the streambed and reducing incision and in storing groundwater near the floodplains. However, we recommend continued monitoring to confirm their effectiveness as the tributary continues to evolve.

Ecological Appraisal of an Urban Creek Daylighting Project: Wildcat Creek at Davis Park

Fri, 13 Oct 2023 00:00:00 +0000

We conducted an appraisal of an urban creek daylighting project in San Pablo, California, to evaluate the ecological integrity of the restoration, understand if the project achieved its goals, and recommend planning guidelines for future projects. This 2013 project in John Herbert Davis Park daylit a 550 foot culverted section of Wildcat Creek, with objectives to improve flood control, create riparian and fish habitat, and expand trail access. We analyzed current project conditions by surveying vegetation at 8 transects, surveying vegetation by planting section, conducting 2 bird counts, mapping the creek bed and vegetation cover, and recapturing 15 photopoints. We compared results with initial plans and monitoring, which continued for 5 years.We found that the project created a riparian vegetation community with habitat supporting bird abundance, density, species richness, and diversity. Willow trees make up 80% of the overstory plants, as a result of an initial 560 willows planted....

Tracing the Alhambra Wash: Past, Present, and Future

Sun, 24 Oct 2021 00:00:00 +0000

Large-scale channelization of Los Angeles water courses in the 20th century led to the invisibility of waterin today’s highly urban, infrastructural landscape. Though channels were built to protect the populationfrom flood risks, they do not provide a long-term solution for flood control, and they disconnect thepopulation from their landscape and local ecology. Revealing local waterways to the public in thoughtfulways may reconnect people to the land’s ecological history and inform future land use decisions for amore resilient future. With this goal in mind, I frame this paper within the context of a lesser-knowntributary in the San Gabriel Valley region of Los Angeles County: the Alhambra Wash. I trace the history, existing conditions, and potential interventions for the wash with the aim of building stronger cognitiveconnections between the local community and their waterway.

Flood Risk Management and the Levee Effect in West Sacramento, California

Sun, 24 Oct 2021 00:00:00 +0000

This paper examines flood risk management and floodplain development in WestSacramento, a flood prone California city adjacent to the state capital. While Sest Sacramentoparticipates in the National Flood Insurance Program, the Flood Insurance Rate Map for the cityis outdated and does not adequately reflect actual flood risk. Analyses of US Census data,National Flood Insurance Program products, zoning ordinances, and remote sensing dataindicate that development has continued in areas exposed to high flood hazard, increasing the risk of life and property to flooding.

Tassajara Creek, Twenty Years Later: Long-term riparian vegetation restoration monitoring using field surveys and remote sensing

Sun, 24 Oct 2021 00:00:00 +0000

Actively incising Lower Tassajara Creek in Dublin, California, was restored as acompound channel in 1999-2000 to mitigate incision and provide flood conveyancecapacity to reduce flood risk to an adjacent greenfield residential development. Thecompound channel design incorporated wide floodplain terraces, planted with nativeriparian and upland vegetation. Prior geomorphological and ecological studies conductedin the first decade after the restoration project suggested that the project hadsuccessfully halted channel incision and that riparian vegetation was developing. I builtupon the last vegetation study in 2008, recreating the photo monitoring points andresurveying the established vegetation transects for the Tassajara Creek project’snorthern reach. I also used remote sensing to quantify changes in vegetation cover overthe last decade, finding a 63% increase in vegetation cover. Both field and remote sensinganalyses indicated continued tree canopy growth and maturation of the...

Water Pollution Resulting from Homeless Encampments in Creeks: Programs in Sacramento, Santa Cruz, and San Pablo

Sun, 24 Oct 2021 00:00:00 +0000

The purpose of this research is to provide a holistic snapshot of how different Sacramento, Santa Cruz, and San Pablo monitoring and mitigating water quality issues posed by tent encampments in waterways. For Sacramento, a look into the “Mile Stewards” Program illustrates one effective effort for removing debris from the American River Parkway. In Santa Cruz, the Downtown Streets Team incorporates people experiencing homelessness into their organizational model, which provides the people a sense of purpose and helps keep the banks of the San Lorenzo River clean. In San Pablo, there are ongoing trash removal efforts at both a city level through volunteer and city employee support and at a county level through CORE Creeks. All three cities are on the path to incorporating necessary social programs with environmental protection to work with people experiencing homelessness and tackle water quality issues resulting from tent encampments in the riparian corridor.

Post-Occupancy Evaluation Affected by Seasons: A Case Study of Waterfront Green Belt Along Yitong River in Changchun City

Sun, 24 Oct 2021 00:00:00 +0000

The vitality and user experience of outdoor public places in high latitudes often change drastically with the change of seasons. This survey carried out Post-Occupancy Evaluation for different seasons on the green belt along the Yitong River in Changchun City since the current one is for summer. Through a field and online survey, documented the special behavior of users in winter, the influence of the season on users of different ages, living distances, and limitations of the current infrastructure. Finally, the analysis drew the following conclusions, the season will affect the travel frequency of residents, especially those who live far away and relatively young. Seasons will also affect residents' evaluation of riverside infrastructure. There is a lack of pedestrian bridges. At present, there are more users in the southern section of Changchun on the Yitong River than in the northern sectio
