This layer shows rivers and streams in the Dinaric Alps region. Data were collected in the framework of the DIKTAS project. For more information, visit the DIKTAS project...

The total surface area of the Adriatic basin in the four countries is 65,545 km² while the Black Sea basin covers 44,865 km² of the project area. Dash lines represent the limit...

Water accounts for the main source of production of electrical power in the Dinaric Alps, and contribute significantly to the countries’ economies. Albania gains 83 % of all...

Landfills are rarely properly constructed or lined and therefore represent a potential source of contamination.Solid waste in the form of hundreds of unregulated landfills and...

Groundwaters of the Dinaric Karst form some of the world's largest karst aquifer systems. The Dinaric region contains huge amounts of high quality groundwater. It is one of the...

We developed spatial summary (GIS) layers for a study of factors influencing the distribution of cave and karst associated fauna within the Appalachian Landscape Conservation...

The Winchester 30 x 60 minute quadrangle, covering northern Virginia, West Virginia, and Maryland, hosts karsts within carbonate units of Devonian to Cambrian age. Lidar-derived...

Subterranean estuaries extend inland into density-stratified coastal carbonate aquifers that contain a surprising diversity of endemic animals (mostly crustaceans) within a...

In 2019, dye tracing investigations were conducted near Manitou Cave in Dekalb County, northeast Alabama. The purpose of the dye tracing was to delineate a recharge area for the...

Surface electrical resistivity tomography (ERT), electromagnetic induction (EMI), and self-potential (SP) data were acquired March 9 - 20, 2018 by the U.S. Geological Survey, in...
