Assessing the impact of land use and land cover changes on river diversions in semi-arid river basins
The study will evaluate historical land use and land cover changes (LULCC) by 1) delineating the lands irrigated by diversions based on water rights databases, 2) summarizing annual LULCC within the irrigated lands using historical satellite imagery, and 3) quantifying LULCC over time. The statistical models will be useful in the Boise Project for improving planning hydrology models that simulate water demands and diversions and provide an example of how the geospatial data could be used in other river basins. Better data and statistical models could help inform decision makers and potentially lead to improved system management.
Need and Benefit
This study addresses the need to develop approaches for assessing how land use and land cover changes affect diversions, so that these effects can be better simulated in planning and predictive models and understood for decision making.
