Incorporated models or components:

Spatial dimensions	2D
Spatial extent	Global, Continental
Model domain	Hydrology
One-line model description	Community Water Model (CWatM) is a hydrological model simulating the water cycle daily at global and local levels, historically and into the future
Extended model description	The Community Water Model (CWatM) is an integrated hydrological and channel routing model developed at the International Institute for Applied Systems Analysis (IIASA). CWatM quantifies water availability, human water use, and the effect of water infrastructure, e.g., reservoirs, groundwater pumping, and irrigation, in regional water resources management.
