The Solinst Waterloo Multilevel groundwater monitoring system is a modular MLS designed to collect groundwater data from multiple depths within a single borehole via a series of monitoring ports positioned at specific intervals along 2-inch ID Schedule 80 PVC casing. The various monitoring ports can be connected to a combination of: sampling ...
United States Department of the Interior National Park Service NPScape is a landscape dynamics monitoring project that provides landscape-level data, tools, and evaluations for natural resource management, planning, and interpretation. [11] Government ArcGIS server addresses: Curated list of 3,500+ ArcGIS server addresses from federal to local.
Therefore, older data using "cataloging units" may differ from newer, higher resolution data using "subbasins".

The USGS Coastal and Marine Science Center (formerly the USGS Center for Coastal Geology) has three sites, one for the Atlantic Ocean (located in Woods Hole, Massachusetts), one for the Pacific Ocean (located in Santa Cruz, California) and one for the Gulf of Mexico (located on the University of South Florida's St. Petersburg campus). The goal ...
The Center for Earth Resources Observation and Science (EROS) is a United States Geological Survey data management, systems development, and research field center It serves as the national archive of remotely sensed images of the Earth's land surface acquired by civilian satellites and aircraft.
The applicability of a groundwater model to a real situation depends on the accuracy of the input data and the parameters. Determination of these requires considerable study, like collection of hydrological data (rainfall, evapotranspiration, irrigation, drainage) and determination of the parameters mentioned before including pumping tests. As ...
