Basin-level Approach to Climate Induced Changes in Southern CA
Watersheds (Santa Ana, San Gabriel, Los Angeles Rivers)
General Direction of Project
„

„
Sediment fluxes
Fluvial discharge of black carbon and
other compounds
Surface water storage
Approach
„
„
Utilize already established
infrastructure to measure basin-level
response.
Utilize mobile technology to sample at
different spatial scales.
