| Summary: | The reasons of suspended sediment formation in the canals of polder systems are analyzed in the paper. The paper describes a mechanism of carrying out these sediments into natural water basins (rivers and lakes) while the water being pumped by pumping stations. Measures for increasing strength of canal slopes performing under a changeable level regime are proposed in the paper. The paper contains methodology for determination of allowable rates of lowering a water level in the river-bed during pumping process. In order to prevent basin silting it is suggested toform settling ponds at polder systems. The methods for determination of ponds’ parameters are presented in the paper. |
