Abstract: Side weirs are frequently used for water-level control in irrigation systems, sewer networks, and flood protection. Researches on side weirs have generally focused on determining the hydraulic characteristics of sharp-crested ...

Abstract: In this study, water flow over rectangular sharp-crested side weirs of various heights and widths was investigated. The distribution of the three-dimensional velocity over the crest and in the vicinity of the side weir was ...

Abstract: When a dam is constructed on a river to store water, sediments transported by the water flow are also stored and reservoir capacity is gradually reduced by sediment accumulation. Prediction of sediment distribution in ...

Abstract: Sharp-crested weirs are widely applied in agricultural and hydraulic engineering for measuring and regulating flow. The various shapes of weirs give rise to their special characteristics. This study introduces a novel ...

Abstract: The side sluice gate is used in open channels to divert a part of flow to a side channel and to regulate the head of distributaries. In present study, the distribution of the three-dimensional velocity in the vicinity of ...

Abstract: A series of laboratory experiments were carried out to study the hydrodynamics of flow through and over permeable grade-control structures with different dimensions and degrees of permeability. The local erosion downstream ...

Abstract: The main aim of this study was to develop an index to determine groundwater drought. Then, as a case study, for the sustainable use of groundwater, the optimum cropping pattern was determined in full compliance with the ...
