Project Goal
The San Antonio River Authority (SARA) began the Regional Watershed Modeling System (RWMS) development to address issues related with water resources comprehensively and collectively throughout the San Antonio River Basin. In the first phase, a prototype hydrologic and hydraulic system (HIS) component was developed. The prototype system will serve as a core for the enterprise Geographical Information Systems (GIS) integrated RWMS, and is one of the first applications of its kind. It is planned to be a full-blown, fully integrated enterprise water resources/environmental modeling system that will bring efficiency and time and money savings by streamlining the modeling process.
In one year, SARA built the Information Technology (IT) infrastructure for GIS, composed of the enterprise GIS database and associated Internet map and metadata services, applications and standards, and published the outcomes of the first phase of RWMS development using these.
SARA has provided training and demonstrations in GIS for internal users and local and regional agencies, and disseminated the related developments together with project partners at conferences. SARA, along with its local partners, will continue to strive for the best use of information technology and its GIS components.

Business Problem Solved
GIS streamlined the process of modeling, regional and local planning, management and implementation activities related with water resources projects. It helped to visualize and analyze region-wide water resources issues, needs, project prioritizations, etc.
SARA uses GIS to identify, prioritize and implement the water resources projects in the region in a timely and cost effective manner.
GIS helped SARA in water resources and environmental modeling activities and in sharing the outcomes of the activities with the public.
GIS also helped SARA in floodplain management, flood mitigation and recovery efforts throughout the region.
Additionally, it has been used for near-real-time and real-time modeling efforts, regional water resources allocation and planning, parks and recreational planning, utility service expansion planning and many other activities at SARA, all of which benefit the communities in our district.
Technology Implemented
The San Antonio River Authority (SARA) has used the ESRI server, database and web products ArcSDE 8.3 and ArcIMS 4.01 to build the Geographical Information Systems-Information Technology (GIS-IT) infrastructure.
SARA used ArcIMS 4.0.1/ArcSDE 8.3 technology (ArcIMS/Metadata Explorer) built on Windows 2003 Enterprise Server, together with the Tomcat 4.1.12 Servlet Engine, Java SDK 4.0.1/JSP and IIS 6/ArcXML, viewable by both Internet Explorer and Netscape browser users, to publish the prototype hydrologic and hydraulic modeling system component (HIS) and associated documentation developed using ArcGIS 9.0 beta/prerelease versions, Model Builder, and VB/VBA Programming/Scripting.
At the time of the web publication of this component, neither ArcSDE 8.3 nor ArcIMS 4.0.1 technology was endorsed or tested by ESRI on these server environments. ArcIMS and ArcSDE technology was customized to serve the ArcGIS 9.0 beta/prerelease Model Builder Application called “Map2Map.” SARA conducted training and demonstrations for internal users and other local and regional agencies on GIS, HIS and Map2Map, its first prototype product.
