Abstract:
This watershed boundary file is created for Tyler Creek through BASINS automatic delineation tool during 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.
