Planning for Arizona’s Water Future

Planning for Arizona’s Water Future

The Central Arizona Project Service Model (CAP:SAM) is a GoldSim model that simulated water demands for more than 100 major water users in the CAP service area, and 16 different supply types used to meet their demands. The model was used to simulate a wide range of future conditions including variable rates and patterns of growth, shortage impacts, effluent reuse, aquifer recharge and recovery, and complex supply portfolio management decisions. The model performed many interrelated calculations for various types of water uses and relies heavily on data managed in a relational database. The complex calculations performed in this model would be difficult or impractical to implement using spreadsheets or traditional computer code. The use of GoldSim allowed for a more transparent, accessible approach and helps facilitate interactions among stakeholders and robust decision making.
