The stability of a dam can be analysed in the following steps: i. Consider unit length of the dam. ii. Work out the magnitude and dimensions of all the vertical forces acting on the dam and their algebraic sum, i.e. ...

Evaporation and its Methods of Measurement
What is Evaporation and How it Occurs? Before rainfall reaches the outlet of a basin as runoff, certain demands of the catchment such as interception, depression storage and infiltration have to be met. Besides these, evaporation and transpiration processes transfer ...

Major Dams in the World and its Roles
Dams are solid barriers constructed across a river or a natural stream to create an artificial reservoir on its upstream side for storing water. It may also be constructed to facilitate diversion of water from the river or to retain ...
