EconWEAP

The paper introduces EconWEAP, a model integrating the State Wide Economic Agricultural Production Model (SWAP) and the Water Evaluation and Planning (WEAP) system to analyze the economic and hydrological impacts of climate change on water resource allocations.

• EconWEAP is a methodological integration of the State Wide Economic Agricultural Production Model (SWAP), which is an agricultural economic optimization model, and Water Evaluation and Planning (WEAP), a climate-driven hydrological model.
• The model utilizes a step function approximation of water demand curves from SWAP within an iterative search process to estimate crop land allocation based on economic value and annual regional water availability.
• Application of the EconWEAP model to California’s Central Valley demonstrated a significant increase in revenues compared to using WEAP alone, achieved through the economically optimal allocation of water while maintaining the same hydrology.
