Dendritic Watersheds

All Watersheds are Modeled with HEC Software

“Florida” Mixed Watersheds

Mixture of Models, AdICPR, SWMM5, etc.

The Digital Watershed (and Model Information System)Note the digital watershed database has a standard design (schema), but different features within it are

used to describe different types of watersheds
