Exploring climate change impacts on water supplies from the Weber River Basin

This project came from a request by Weber Basin Water Conservancy district to explore climate change impacts to the Weber River water supply in collaboration with the Utah Division of Water Resources (UTDWR). UTDWR has developed a water supply model for the Weber River, which has been re-coded from the original Fortran to integrate into the Water Evaluation And Planning (WEAP) model by Utah State University (USU). The goal of the project is to develop relevant and defensible climate change scenarios and climate perturbed hydrologies, using the CBRFC model and evaluate impacts to the current operations of the Weber River system. Recently published tree-ring reconstructed streamflows may also be evaluated to explore extreme drought conditions beyond those in the observed record. The model will facilitate the exploration of a variety of new management, infrastructure, or demand changes to retain a resilient system. Initial work has focused on evaluating climate change sensitivities across multiple flow points on the Weber river and addressing evapotranspiration and model calibration.

Presentation and report to Weber Basin Water Conservancy District forthcoming
