Pre Conference Seminar3 Watershed Data Management - Modular Solutions Standard Feature Maintenance Tailored Model Maintenance RWMS SWMM5 RWMS HEC HEC-RAS HEC-HMS 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 Smart Translator Smart Translators RWMS Tools Model Maintenance DCS* and DFIRM Databases 1 3 AdICPR, etc 4 2 Feature Maintenance Model Maintenance Tier One: National Standard Tier Two: Model Specific Standards

Pre Conference Seminar4 Regional Watershed Modeling System (RWMS) Developed by PBS&J for the San Antonio River AuthorityDeveloped by PBS&J for the San Antonio River Authority –Contributions from UT Austin and Texas A&M University Will ultimately use an Arc Hydro compliant data model for the underlying watershed and stream networkWill ultimately use an Arc Hydro compliant data model for the underlying watershed and stream network Defines “Interface Data Models” for HEC-HMS and HEC- RASDefines “Interface Data Models” for HEC-HMS and HEC- RAS –Entire content of models ingested into an ArcGIS Geodatabase
