Abstract
This paper envisages the ecological and civil engineering aspect of check-dam construction in a micro watershed environment for preventing possible soil erosion and silt wastage due to strong current by small streams or river tributaries. The field study was done for checking the feasibility of construction of check-dam over Keshka River, in Tundi block of district Dhanbad, Jharkhand. The physical, ecological, social and economic factors were also noticed during the evaluation of the check-dam. It was observed that the river tributary at Keshka had one of the most unpredictable water current and thus, a proposed check-dam would , firstly, check any abrupt increase in the water flow in the this area. Secondly, due to the strong current of the river, the gully erosion is quite heavily prevalently noticed in the area which can further lead to the decrement of soil quality and basic soil texture, due to silt wastage. Also, considering the ecological aspect, the water if controlled can be used in the near-by irrigation purpose, through which farmers having their land(s) adjoining to the proposed check-dam, would have a high moisture content, and thus, they could enhance the soil water percolation rate of their soil, and on an overall scenario, the ecological aspects also can be enhanced of this area.Further, this will increase ground water level in nearby areas through quick recharge of drinking as well as irrigation wells.
