Question

The water table in a well increases by 0.2 m over a day after a period of heavy rainfall. The specific yield of the aquifer is 0.05.Calculate the amount of recharge required

Answer 1

Answer:

Explanation:

It is often of interest to know how water is flowing in the vicinity of a pumping well. A very useful solution to Laplace's equation is that for steady radial flow, which applies to flow in the vicinity of a pumping well. This solution assumes radial flow toward a well, so it makes sense to formulate the solution in terms of a radial coordinate r centered on the well, as shown in Figure 7.3. The origin of the coordinate system is taken as the centerline of the well. With this solution, all flow is radially symmetric in the r direction.
