Abstract

Aim: The aim of study was to develop an analytical procedure to improve the sediment removal efficiency of the sediment settling basin with a better design, conserve the cultivated land and application of the design model.

Materials and Methods: The adopted analytic approach assumed the prevalence of velocity distribution in uniform flow conditions and used simplified one-dimensional equations to insure reduced flow turbulence by determining Froude Number. The proposed procedure led on periodical flushing of the sediment basin and on the offer of an alternative option to insert inclined plates in the basin to improve its loading rate and to upgrade its trapping efficiency. In the model, geometric configurations of the basin were identified, which can remove even the fine sediment (0.055 to 0.22mm) from the flow with high removal efficiency determined following Camp (1946).

Results: The application of the scheduled flushing mode of operation proposed by the developed model revealed a substantial reduction in the area occupied by the basins with higher trapping efficiency. Application of the analytical design procedure for the design of efficient sediment basins in earth irrigation canals supplied with sediment-laden water resulted in the economizing area occupied by the basin system compared to current designs. Employing the concept of periodical flushing of sediment-laden water resulted in the reduction of basin capacity compared to end-season flushing recommended by many consultants.

Conclusion: It was concluded that these results have an important role in optimizing the design to enhance the Small Sediment removal efficiency of the settling basin.
