Data Assimilation Water Use and Agricultural Productivity
The data assimilation Water Use and Agricultural Productivity (daWUAP) project is a hydro-economic model that couples an economic model of agricultural production calibrated using positive mathematical programming (PMP) and a semidistributed rainfall-runoff-routing model that simulates water available to producers.
daWUAP is an open-source, cross-platform Python library for conducting hydro-economic assessments of agricultural water use. User-provided hydrology data (stream network, basins, and climate data) are combined with economic and productivity data on water users (i.e., farmers) to estimate changes in water availability and/ or crop land allocations under varying hydrologic regimes or farmer decision-making scenarios.
- Hydrologic rainfall routing model to simulate water availability;
- Spatially and temporally explicit snowmelt and AET estimates along with stream-flow time series;
- Economic modeling of agricultural production under Constant Elasticity of Substituion for water, land constraints using Positive Mathematical Programming (PMP);
- Stochastic data assimilation (via Kalman filter) of farm observational data for estimating variance in economic model parameters;
- Simulation of farmer behavior and agricultural production;
- Coupled hydrologic-economic modeling of water availability, farmer behavior and agricultural production in order to quantify how farming decisions affect agricultural water supplies;
