Abstract
In the water crisis area, crop production is the most difficult task due to low resource of water; rainwater is the only source and its effective use for successful crop production. In addition, the uncertainty in rain conditions resulting water shortages. The proper management of rain water, conservation and development of water resources is necessary to meet the needs for domestic use, drinking water, industrial use, irrigation etc. Since watershed is a hydrological entity, water resources planning and its utilization are best attempted by taking watershed as a unit of planning. Rain water management often involves interventions for runoff control and retention such as bunds and vegetative barriers and also water harvesting structures (e.g. farm ponds, check dams) and ground water recharge structures (e.g. Nala bunds and percolation tanks). All this is designed according to the intervention runoff, which resulted in the level of water above it. The basic natural resources, such as water, soil and water quantity and quality, decide to produce biomass in a basin and therefore maintain the human and livestock population. Therefore, while planning the use of resources, this aspect of the basin must be. A higher population will increase the pressure on the basin resources, resulting in a result of earthquake and resources resulting in a decrease in the result. The geographical area that drains to a common exit point in a drainage line is called a basin. The area of the river basin is always defined with reference to an exit point in a drainage line. The area of the watershed increases as we move downstream along a drainage line and decreases as we move upstream. A very large river basin is called a macro basin and a very small basin is called a micro basin. The micro basin generally has a single order flow as its drainage line where a macro basin has multiple higher order drainage lines
