Research Project: Kings River Snow Modeling

Location: Watershed Management Research

Project Number: 2052-13610-012-30-T
Project Type: Trust Fund Cooperative Agreement

Start Date: Oct 1, 2018
End Date: Sep 30, 2019

Objective:
The objective of this agreement is for the Agricultural Research Service (ARS), in coordination with California Department of Water Resources, to run and maintain near real time iSnobal simulation in the Kings River Watershed for water year 2019 using the Automated Water Supply Model (AWSM). The snowpack state will be updated periodically with Airborne Snow Observatory (ASO) snow depth measurements. Simulation results will provide valuable snowpack information to the Kings River Watershed Association (KRWA) and help achieve the broader goal of advancing runoff forecasting through physically based modeling and measurements.

Approach:
Provide Kings River Water Association managers information on the modeled snowpack through real time simulations of the snowpack state using a physically based snow model, iSnobal, for the Kings River Watershed. The project will utilize the Automated Water Supply Model (AWSM) to facilitate the iSnobal simulations and Airborne Snow Observatory (ASO) updating after an overflight to produce timely reports about the current snowpack state. ARS will maintain AWSM for the Kings River Watershed throughout the snow season from October to July and provide modeled density to ASO before an overflight.
