watershed boundary definition

boundary that represents the contributing area for a particular control point or outlet • Used to define boundaries of the study area, and/or to divide the study area into sub-areas. Topographic maps; for example, have a scale of 1:24,000 (which means that one inch measured on the map represents 24,000 inches (2000 feet) on the ground). A drop of water falling outside of the boundary will drain to another watershed. watershed Has Geographic Origins How to use watershed in a sentence.

The huge watershed of the Hudson covers about directly on the watershed boundary will be split between the watersheds on either side. Watershed management is the study of the relevant characteristics of a watershed aimed at the sustainable distribution of its resources and the process of creating and implementing plans, programs and projects to sustain and enhance watershed functions that affect the plant, animal, and human communities within the watershed boundary. That is, the entire drainage area of a major river like the Merrimack can be considered a watershed, but the drainage areas of each of its tributaries are also watersheds. de la péninsule Tangil, en suivant la baie Laskeek, le bras Logan et le bras Crescent jusqu'à son intersection avec la ligne droite qui relie le coin nord-est du lot de district 663 et le, le bras Logan, ledit sommet étant situé par environ 52°46?37?
