Finding lost reservoirs: Using AML to automate reservoir geolocation
The Reservoir Sedimentation Survey Information System (RESIS) is the most comprehensive database of reservoir sedimentation rates in the world, comprising nearly 6,000 surveys for 1,819 reservoirs across the United States. The use of this database has been limited by the lack of precise coordinates for the reservoirs. Many of the reservoirs postdate current USGS topographic maps and have only township and range coordinates. This paper presents a method scripted in Esri's ARC Macro Language (AML) to locate the reservoirs on 30-meter digital elevation models using available reservoir information. The script then delineates the contributing watersheds and compiles several hydrologically important parameters for each reservoir.
