Arc Hydro and the Regional Watershed Modeling System in Texas William Burmeister, P.E. PBS&J, San Antonio, Texas Pre Conference Seminars
Presentation Overview • RWMS Background • Data Management • Key Components • Interface Data Models • Workbench • Internet Portal • Additional Tools • Next Steps Pre Conference Seminar
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 Tier One: National Standard Feature Maintenance All Watersheds are Modeled with HEC Software Mixture of Models, AdICPR, SWMM5, etc. “Florida” Mixed Watersheds Dendritic Watersheds 1 Tier Two: Model Specific Standards Smart Translators AdICPR, etc Smart Translator DCS* and DFIRM Databases RWMSHEC RWMS SWMM5 Model Maintenance RWMS Tools Model Maintenance HEC-RAS HEC-HMS 4 2 3 Watershed Data Management - Modular SolutionsStandard Feature Maintenance Tailored Model Maintenance Pre Conference Seminar
Regional Watershed Modeling System (RWMS) • Developed 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 network • Defines “Interface Data Models” for HEC-HMS and HEC-RAS • Entire content of models ingested into an ArcGIS Geodatabase Pre Conference Seminar
RWMS Concept • Efficiently Manage Updates to Hydrologic, Hydraulic and other Models • Regional Integration • Maintain “Current” Models • Web Portal for End Users • Checkout and submittal of models • Management of study workflow • Ensure Notification and Coordination • Enforce Standards and Facilitate Study Review Pre Conference Seminar
RWMS Data Management Pre Conference Seminar
Underlying RWMS Database Concepts Pre Conference Seminar
RWMS Development Approach • ESRI ArcGIS-Based • Data Management: ArcSDE with SQL Server • System Interaction: ArcGIS Desktop and ArcIMS • Model Specific Geodatabases (IDMs) • Manage, maintain and integrate models • Administrator and End User Tools • Administrator: Workbench (ArcGIS Desktop) • End User: Web Portal (ArcIMS) • Tools for Model Review and Integration • Tools to Link Models • Platform Independent for End User Pre Conference Seminar
Feature Class Elements of HEC-HMS IDM • HMS Basin Feature Class • HMS Project Feature Class • Gages • Rainfall Grids Pre Conference Seminar
HEC-HMS Interface Data Model Pre Conference Seminar
Feature Class Elements of HEC-RAS IDM Pre Conference Seminar
HEC-RAS Interface Data Model Pre Conference Seminar
