In cooperation with the Puerto Rico Environmental Quality Board, the U.S. Geological Survey (USGS) calculated over 40 different basin characteristics as part of preparing the Puerto Rico StreamStats application. These data were used to update the peak flow and low flow regression equations for Puerto Rico. These datasets are raster representations of various environmental, geological, and land use attributes within the Puerto Rico StreamStats 2020 study area, and will be served in the Puerto Rico StreamStats 2020 application to describe delineated watersheds. The StreamStats application provides access to spatial analytical tools that are useful for water-resources planning and management, and for engineering and...

This map is a digital update of The karst landforms of PuertoRico (Monroe, 1976). In this new version the karst areas onthe islands of Mona and Monito have been added from Briggs and Seiders (1972). This mapwill serve as the basis for the Puerto Rico portion of a newnational karst map currently being compiled by the U.S.Geological Survey. In addition, this product serves as astandalone, citable source of digital karst data for Puerto Rico.Nearly 25 percent of the United States is underlain by karst terrain, and alarge part of this area is undergoing urban and industrialdevelopment. Accurate delineations of karstic rocks are neededat the national, state, and local scales. These data will lead to abetter understanding...

Monroe County in southeastern West Virginia hosts world-class karst within carbonate units of Mississippian and Ordovician age. Lidar-derived elevation data acquired in late December of 2016 were used to create a 3-meter resolution working digital elevation model (DEM), from which surface depressions were identified using a semi-automated workflow in ArcGIS®. Depressions in the automated inventory were systematically checked by a geologist within a grid of 1.5 square kilometer tiles using aerial imagery, lidar-derived imagery, and 3D viewing of the lidar imagery. Distinguishing features such as modification by human activities or hydrological significance (stream sink, ephemerally ponded, etc.) were noted wherever...
