Deep carbon storage potential of buried floodplain soils

Soils account for the largest terrestrial pool of carbon and have the potential for even greater quantities of carbon sequestration. Typical soil carbon (C) stocks used in global carbon models only account for the upper 1 meter of soil. Previously unaccounted for deep carbon pools (>1 m) were...

Not all breaks are equal: Variable hydrologic and geomorphic responses to intentional levee breaches along the lower Cosumnes River, California

The transport of water and sediment from rivers to adjacent floodplains helps generate complex floodplain, wetland, and riparian ecosystems. However, riverside levees restrict lateral connectivity of water and sediment during flood pulses, making the re-introduction of floodplain hydrogeomorphic...

Alison Whipple named Delta Science Fellow

UC Water and UC Davis Climate Change, Water, and Society IGERT PhD candidate Alison Whipple has worked in the California Delta for many years, producing the San Francisco Estuary Institute's important and beautiful book titled Sacramento-San Joaquin Delta Historical Ecology Study . In March 2016 that experience paid off. Whipple was awarded a prestigious Delta Science Fellowship to continue her research on achieving more functional landscapes through land-water interactions. Advised by Prof. Joshua Viers, Whipple's focus on spatio-temporal variation of floodplain habitat for restoration...

Cosumnes Research Group

The Cosumnes River is the only free-flowing river on the west slope of the Sierra Nevada, and because of its natural flow regime it has become the centerpiece for decades-long research on the benefit of floodplain reconnection for the purposes of ecological restoration and preservation of ecosystem services, such as local groundwater recharge, flood wave attenuation, and temporal spawning habitat for native fishes, such as splittail, and rearing habitat for juvenile anadromous salmonids, such as chinook salmon.

Characterizing Past and Future Flood Regimes of California's Cosumnes River: A Hydroinformatic Approach

As the only major undammed river on the west slope of California's Sierra Nevada, with over 100 years of USGS streamflow data, and the location of several floodplain conservation and restoration efforts, the Cosumnes River offers a unique opportunity to study connections between a river's flow...

Using high resolution subsurface modeling in managed aquifer recharge

The elimination of baseflow due to declining groundwater levels has compromised many ecological functions of the Cosumnes River. Numerical modeling has shown that floodplain reconnection can be a viable method to increase groundwater recharge - mitigating overdraft and helping re-establish...

Floodplain Heterogeneity Drives Riparian Vegetation Composition and Structure Through Channel Meander Migration and Channel Abandonment

Riparian vegetation composition and structure reflect the legacy of fine- and coarse-scale patterns of hydrology, geomorphology and ecology. Understanding the dynamics of complex systems requires scaling-up mechanistic patterns and processes. Coupling hydro-geomorphic processes with vegetation...

Perennial pepperweed invasion on a restored seasonal floodplain

The science of restoration ecology emphasizes the importance of managing, and often manipulating, both physical and biotic factors to facilitate ecosystem recovery. Among many other factors, our investigation of successful riparian floodplain restoration has focused on the positive impact of...
