The activity of watershed delineation is typically performed by geographers, scientists, and engineers. Historically, watershed delineation was done by hand on paper topographic maps, sometimes supplemented with field research. In the 1980s, automated methods were developed for watershed delineation with computers and electronic data, and these ...
Watersheds may also be defined in the continuous domain. [1] There are also many different algorithms to compute watersheds. Watershed algorithms are used in image processing primarily for object segmentation purposes, that is, for separating different objects in an image. This allows for counting the objects or for further analysis of the ...
Watershed management, the management of drainage basins; Watershed Protection and Flood Prevention Act, a United States law controlling drainage and water storage; Watershed district (Minnesota), one of a number of government entities in the US state of Minnesota which monitor and regulate the use of water in drainage basins
The National Map is a significant contribution to the U.S. National Spatial Data Infrastructure (NSDI) from the Federal Geographic Data Committee (FGDC) and currently is being transformed to better serve the geospatial community by providing high quality, integrated geospatial data and improved products and services including new generation ...
A topographic survey is typically based upon a systematic observation and published as a map series, made up of two or more map sheets that combine to form the whole map. A topographic map series uses a common specification that includes the range of cartographic symbols employed, as well as a standard geodetic framework that defines the map ...
Additionally, by 2028 the Commission aims to identify and map where there are interconnections and dependencies of DWR-owned or controlled infrastructure systems and identify where areas of flood ...
The process of finding a drainage boundary is referred to as watershed delineation. Finding the area and extent of a drainage basin is an important step in many areas of science and engineering. Most of the water that discharges from the basin outlet originated as precipitation falling on the basin. [11]
Robert "Bobby" Cavanaugh, of Madison Heights, Michigan, was beaten to death on Christmas Eve after he tried to save a dog who was being abused by a neighbor and alleged repeated felon, witnesses said.
