Determining the appropriate amount of river water consumption and the ecological boundary range of the alazman river

Rivers are one of the most important components of nature, which is known as a vital factor due to the flow of water, which can meet the needs of the inhabitants of the river. Violation of riverbeds and increasing population has caused the destruction and change of the river's environmental conditions and increased the negative impact factor and reduced the possibility of using the river's water potentials. Pollution due to the entry of chemical fertilizers and sewage into the river, improper exploitation of sand in the riverbed and construction along the river due to unprofessional exploitation and encroachment on the river, which has irreversible effects on the river. If the boundaries of rivers are determined, possible damage to the environment can be prevented and surface water resources can be used optimally. In this article, First the hydraulic condition and hydrology of the river were studied and then the environmental status and land use of the region are determined and then studies have been carried out to determine the environmental range of the Alazman River in accordance with the instructions set by the Ministry of Energy. In order to determine the quality area, it is necessary to determine the classification of this river, which was obtained for Alazman river, class 5, and the ecological range obtained for this river, for the first, second and third areas, is 20, 22 and 108 meters, respectively
