MD-DE-DC WSC Water Use & Water Supply Capabilities
In Maryland, public supply water is delivered to users for domestic, commercial, and industrial purposes. Most is used for public services, such as public pools, parks, firefighting, water and wastewater treatment, and municipal buildings, and some is unaccounted for because of leaks, flushing, tower maintenance, and other system losses. 5.7 million Marylanders get their water from the public...
MD-DE-DC WSC Geomorphology and Sediment Studies Capabilities
Geomorphology is classified as the study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near the Earth's surface. Adding water creates a whole new dynamic known as Fluvial Morphology. Rivers and streams act as conduits of water along with sediment. As water flows over the channel bed, it is able to...
