Estimate

Agricultural extractions were estimated from land use and climate data using the Irrigation Demand Calculator (IDC) within Cosumnes, South American, and North American Model (CoSANA). Domestic (Agricultural-Residential [Ag-Res]) extractions were estimated based on representative indoor and outdoor water use and estimated number of residential parcels in the Basin.
Land use accuracy of 95% based on ground-truthing efforts and comparisons with other mapping methods (e.g., remote sensing).

E Change in Storage


Method used to calculate change in storage

Changes in groundwater storage were calculated using the CoSANA model, the Numerical Model for the Basin. CoSANA is a three-dimensional groundwater flow model that uses DWR?s finite-element Integrated Water Flow Model groundwater modeling platform. CoSANA was prepared to support GSP development and GSP implementation.
