Abstract

The influence of streams is often noted in geology. The surface of the Earth is shaped and sculpted by erosion, transport, and deposition of sediment. A streams are the water bod ies which flows along a naturally made paths on the Earth.The water cycle and mainly amount of precipitation depends upon the stream flow depends on various watershed parameters, including the physico-geological features, land use- land cover, and precipi tation volume, intensity, and frequency. All the living organisms on Earth are dependent on the hydro-logical (water) cycle which in turn depends on the stream flows. One of the primary sources of stream discharge is the precipitation that occurs within and along the stream’s channels. Other sources include groundwater, overland flow, and inter-flow. Recognizing patterns of water flow and developing predictions of flood and drought are both essential in order to adequately monitor water flow. Rivers influence water cycle f lowin manyways, so they are important in the hydrologic cycle. For the purpose of measuring discharge, a simple and objective methodology has been devised by Subramanya (2009) in which the volume of water that moves over a point in a fixed amount of time is referred to as stream flow or discharge. The rate of flow of water in the streams (discharge) is directly proportional to the total amount of runoff from the watershed and water flowing into the streams. Since the climate is dependent on the climate, so is the water flow.

Long-term trends in water and sediment flows can be accurately estimated by relying on the correct estimation of stream discharge. A well-developed construction design, as well as a robust infrastructure that supports it, are both key components in constructing banks and other channels that require correct flow rate information.
