The California Environmental Flows Framework (CEFF) provides an approach for determining ecological flow criteria and guidance for developing environmental flow recommendations that can accommodate a variety of stream types and biological communities, while supporting regulatory and management agency programs aimed at protecting beneficial uses for aquatic life. CEFF applies a Functional Flows approach and provides ecological flow criteria based on the natural variability of ecologically-relevant functional flow metrics. It provides a process for considering physical and biological constraints within a stream system and provides guidance on developing environmental flow recommendations that balance ecological and water management objectives.
As part of numerous other projects, Center for Watershed Sciences staff and researchers have developed code to run analyses, organize and store data, interface with other systems, automate processing, and more. Some of this code is designed to be reusable as standalone products, or as code in other, larger projects. You can find this code below.
Knowledge of species' spatial distributions is crucial to the identification and prioritization of watersheds in need of restoration. Coupled with species' status, the presence and or absence of species can indicate biologically diverse vs. depauperate areas.
The main objective of this project is to quantitatively assess how changes to the landscape through time will impact Swainson’s Hawk (Buteo swainsoni) habtiat and other potentially beneficial ecosystem services. Accounting for this type of natural capital and how ecosystem services change through time is not well documented in the literature and developing this methodology was a secondary objective for our research group.
The Center for Watershed Sciences is partnering with The Nature Conservancy in an experimental floodplain restoration on the Cosumnes River. The Center's role in this Department of Fish & Wildlife funded project, "Wildlife And Vegetation Response to Experimental Restoration of Flooded Riparian Forest Habitat for the Cosumnes River Preserve," is intended to conduct biophysical monitoring of an experimental restoration on approximately 800 acres of flooded riparian forest habitat in the Cosumnes River Preserve.
This website provides preliminary information on irrigated land areas, water use and crop value over various hydrologic boundaries. Information from the California Department of Water Resources (http://www.water.ca.gov/landwateruse/anlwuest.cfm) on land and water use, and economic information from the SWAP model (swap.ucdavis.edu) for 20 crop groups are employed.
PISCES is software and data describing the best-known ranges for California's native fish. The data is compiled from multiple sources and experts and is stored and exported as rangemaps and summary maps. As of December 2013, it includes data on all of the state's 131 native fish taxa as well as 48 non-native species.
Mountain meadow wetlands provide disproportionally important ecological services as compared to the area they cover in the Sierra Nevada by providing wetland-associated biodiversity, attenuating floods, and by contributing to downstream water quality and flow. However, degradation and loss of hydrologic function are widespread in Sierran meadows due to past and continuing anthropogenic effects including grazing management, diversions, roads and culverts, as well as non-native species.
StreamLapse is a software system to build videos from time lapse river photos and data. It allows for rapidly viewing a season of rivers and cross-comparison between sites and years.
