Non-stationary filtration through a homogeneous rectangular closing dike

Abstract

A hydraulic structure is an object for the use of water resources, as well as for combating the harmful effects of water. Knowledge of the main parameters of the filtration flow is necessary for solving problems related to the design and operation of hydraulic structures. The article considers filtration calculations of a homogeneous closing dike, which is: determination of instantaneous filtration flow rate and seepage area. It is proved that when the length of the closing dike increases, the height of the seepage area monotonically decreases; the depression curve is constructed; critical time value after which the flow rate takes a constant value equal to the Dupuis flow rate is found.
