The modes of failure of gravity dam are:- OverTurning or Rotation about toe:- When the resultant force acting at any section if it passes outside the toe, the dam shall rotate or overturn about the toe. In other words, it means that if horizontal forces dominate over vertical forces the...
Duty of Crops (D) The amount of water(i.e. 1cumec of discharge) available for the crop for full growth during the entire base period is called duty. Suppose we are giving 5 cumecs of discharge for 500 hectares of land for a particular crop then Duty = 500/5 =100 hectares/cumec Here,...
