Yakubov Kh.E., Khudaikulov B.S. Assessment of Drainage Efficiency through Mathematical Modeling Methods

This work considers the problem of groundwater rise in poorly drained areas. It is difficult to give the exact solution for inflow of water to perimeter drainage consisting of a group of wells located along a randomly delineated complex contour.

One important task is modeling the water table lowering because of pumping from wells. Lowering of water tables in any point A due to pumping from wells located in several points can be determined under free flow using the F. Forchheimer relationship.

The authors improved the formula for estimating water table lowering for vertical drainage wells. The testing showed that the degree of ground flow disturbance by the vertical drainage system is minor. The wells do not interact, while the cones of depression do not lower to the norm. The volumes of pumping from vertical drainage wells required in order to achieve needed lowering of water table are estimated.
