WELCOME to Arizona State University DCDC's WaterSim Project.
WaterSim is a simulation of water supply and demand for the Phoenix Metropolitan area that integrates information about climate, land use, population growth, and water policy. Adjustable settings allow you to gauge future water-supply conditions in response to climate change, drought, population growth, technological innovation, as well as policy decisions about the nature of the region's built environment, landscaping practices, and recycled water.
WaterSim contains multiple submodels; these submodels work together to simulate the future of our water. Some of the submodels, like the Colorado River shortage sharing agreement, are unchangeable because of legal or natural constraints; others can be adjusted by you. Here are some of the simulation settings that you can adjust:
- Water demand based on population and agricultural use
- Drought conditions on the Colorado River
- Drought conditions on the Salt and Verde Rivers
- The speed at which agriculture can be retired
