PIHMgis

Also known as
Model type	Tool
Model part of larger framework
Note on status model
Date note status model

Incorporated models or components:

Spatial dimensions	2D
Spatial extent	Regional-Scale, Landscape-Scale, Watershed-Scale, Reach-Scale
Model domain	Hydrology
One-line model description	Tightly coupled GIS interface for the Penn State Integrated Hydrologic Model
Extended model description	Physically-based fully-distributed hydrologic models try to simulate hydrologic state variables in space and time while using information regarding heterogeneity in climate, land use, topography and hydrogeology. However incorporating a large number of physical data layers in the hydrologic model requires intensive data development and topology definitions.
