GEOLOGY

Detailed explanation-1: -The outlet, or pour point, is the point on the surface at which water flows out of an area. It is the lowest point along the boundary of a watershed.

Detailed explanation-2: -A watershed is area of land where surface water and runoff converges to one specified point. The end point is usually another river, lake, stream, bay, or ocean.

Detailed explanation-3: -Within the watershed there are locations where sediment is produced, transported, or stored. These zones are often referred to as: source (production), transfer (transport), and response (storage or deposition) (Figure1).

Detailed explanation-4: -A watershed is an area of land that drains all the streams and rainfall to a common outlet such as the outflow of a reservoir, mouth of a bay, or any point along a stream channel.

Detailed explanation-5: -A watershed consists of two major components, water and land, and is made up of many watercourses, including the land surrounding them, all of which drain into a specific point at a lower elevation (see Figure 1).
