Autonomous Underwater Vehicle Water-Quality and Sonar Measurements in Delaware River near Philadelphia, Pennsylvania, 2019 These data sets were created in support of the U.S. Geological Survey's (USGS) Next Generation Water Observing System (NGWOS) for the Delaware River Basin pilot study (Eberts, Wagner, and Woodside, 2019). The NGWOS utilizes real-time data, improved computational capabilities, and new technologies such as the rapid deployment of unmanned aerial vehicle's (UAV) and autonomous underwater vehicle's (AUV) to provide information on water quantity and quality, in more locations, quickly and efficiently (Eberts, Wagner, and Woodside, 2019). Combined with advanced modeling applications, the NGWOS will be an important tool for water-resource managers and emergency management. Water-quality and bathymetric data were measured...

There are various features and mitigation efforts to the SHEP, one of which is the installation of a dissolved-oxygen (DO) injection system at two locations along the Savannah River to maintain pre-SHEP DO levels in the harbor (U.S. Army Corps of Engineers, 2018b). The injection systems are installed upstream near Georgia Power Plant McIntosh in Effingham County, Georgia, and downstream near Hutchinson Island, Chatham County, Georgia. Designed to maintain DO levels in the harbor as they were... Categories: Data; Tags: Back River, Chatham County, Effingham County, Georgia, Hydrology, All tags...
