Problem of Clogging in Drainage Systems in the Examples of the Żur and Podgaje Dams

Abstract Drainage plays an extremely important role in hydraulic structures, such as earth dams. Observations of drainage in hydraulic structures under various soil conditions indicate that the phenomenon of clogging can lead to a radical reduction in the efficiency of drainage, making it non-functional within a few years after construction. This article describes the problems of drainage clogging by iron oxide in the examples of the Żur and Podgaje dams.
