Hydrologic Response Units (HRUs) for the Southern Guam watershed model, PRMS_2016
The hydrologic response units (HRUs) available here were used in the Precipitation Runoff Modeling System (PRMS) of southern Guam documented by Rosa and Hay (2017). A Geographic Information System (GIS) file for the HRUs is provided as a shapefile with attributes ParentHRU, Region, and RegionHRU identifying the numbering convention used in the PRMS_2016 southern Guam model parameter files and Rosa and Hay (2017) report. Hydrologic response units (HRUs) were delineating using the processing steps outlined in Viger and Leavesley (2007) and a 5-meter digital elevation model (DEM) derived by Johnson (2012) using the Joint Airborne LIDAR Bathymetry Technical Center of Expertise topobathy data (National Oceanic and Atmospheric Administration, 2007). Johnson (2012) used the procedures described in Taylor and Nelson Jr. (2008) to derive the DEM and delineate internally drained areas in the karst topography, or areas with closed depressions and their surface drainage basins that contribute runoff to the closed depression. These internally drained areas were then intersected with the initial HRUs to derive the final 317 HRUs for the southern Guam watershed model, PRMS_2016.
