Watershed cerebral infarction account for 5-10% of all cerebral infarctions 8.They tend to occur in the elderly, who have a higher incidence of arterial stenosis and hypotensive episodes, as … watershed is: an area of land from which all the rain flows to a specific river or lake (or underground aquifer for older students). Hydrological parameters such as intensity and duration of rainfall help in quantification of water available in watershed. Physiographic Characteristics Hydrology: The availability, quality and distribution of surface water is basic to the final goal of growing greenery in a watershed. A watershed is an area of land that drains or “sheds” water into a specific waterbody. A large watershed can be managed in plain valley areas or where forest or pasture development is the main objective. CHARACTERISTICS OF WATERSHEDS All characteristics affect the disposal of water. Epidemiology. A watershed can be small, such as a modest inland lake or a single county. The size of a watershed (also called a drainage basin or catchment) is defined on several scales—referred to as its Hydrologic Unit Codes (HUC)—based on the geography that is most relevant to its specific area.

SIZE: It helps in computing parameters like precipitation received, retained, drained off. watershed size also depend on the objectives of the development and terrain slope. A morphometric analysis has been carried out for Rampur watershed of Mahanadi river basin, and its nine sub-watersheds have been prioritized according to the linear, aerial and relief characteristics. Every body of water has a watershed. The management should be carried out on the watershed basis. In hilly areas or where intensive agriculture development is planned, the size of watershed relatively preferred is small. Watershed characteristics associated with the degree of urbanization in each of the study areas were determined for both physical (land cover, infrastructure, hydrologic modifications, soils, topography, and climate) and socioeconomic conditions.
