Southern Guam geospatial information server
About this map:
This map shows the average streamflow (in cubic feet per second) of streams and rivers in southern Guam. The geospatial data were derived by means of GIS spatial analysis techniques using a digital elevation model and average annual rainfall as part of a recent study by the Water and Environmental Research Institute of the Western Pacific (WERI) to predict flow duration curves at ungaged sites. The raw data package for download also includes the average rainfall upstream for stream segments and the drainage area upstream for stream segment. Please note that the exact location and number of streams may differ from other hydrologic data in this atlas as a different model and input datasets were used to derive these datasets. For more information, see the appropriate WERI Technical Report (L.F. Heitz and S. Khosrowpanah, 2015).
