Abstract:
This sub watershed file is created for Tyler Creek through BASINS automatic delineation tool. BASINS generated outlet shape file tyler-outlet-final.shp has been used for sub watershed delineation. During the watershed delineation process, 200 ha of threshold area have been applied for stream definition. NED 1/3 arc second (~ 10 meter resolution) DEM in integer, Z unit in centimeter; downloaded from USGS Seamless data distribution center is also used for watershed delineation.The NED data was downloaded in March 2005. This delineation is processed with a modified DEM after resolving the boundary discrepancy.
