Most of seepage problems in nonsteady state have been studied experimentally because they were frequently impossible to solve theoretically.
The most important point in the nonsteady seepage problem is! how to detetermine the position of free surface...
Most of seepage problems in nonsteady state have been studied experimentally because they were frequently impossible to solve theoretically.
The most important point in the nonsteady seepage problem is! how to detetermine the position of free surface and its variation.
This pliper is studied by experiments on the instantaneous drawdown in the multi layer porous media dam. Especially it is noted that seepage and discharge problems in the estuary dam.
