 Water Demand and Demographic Changes

Image: Water Demand and Demographic Changes
Factors such as population migration, urbanization, and economic development define the water demand in the water resources equation. They drive changes in the lifespan of the nation’s water infrastructure. WRAP researchers are helping to ensure our water infrastructure is adapted—within its natural service time—to future water demand.

In one approach, WRAP scientists take advantage of the other EPA ORD global climate change research program (ICLUS) that is producing the first-ever yearly forecast of nationwide land use change scenarios until 2050. The ICLUS is a computer-based simulation of land use changes under future climatic conditions.

The second approach WRAP researchers are using is the integration of actual land use planning blueprints, water resources engineering, and computer forecasting of future precipitation and runoff. This “bottom-up” approach requires intensive data gathering, detailed watershed and land use studies, and scenario analyses guided by computer simulations. Currently, WRAP researchers are using this approach for studies of the Little Miami watershed in southwestern Ohio.
