Model Information
For more information about this model, go to www.pihm.psu.edu
Spatial Resolution
The model uses an irregular triangular grid, or Delaunay Triangles. The grid is generated using the TRIANGLE program, and the vertical projection of the triangular grid is based on other physical model parameters and required control volumes.
Temporal Resolution
Time steps are variable and range from minutes to hours.
Outputs
Model outputs include hydrologic fluxes and routing.
