Effect of Height of Sharp-Crested Weir on Discharge Coefficient
Authors
Abstract:
Weirs have widely been used for the flow measurement, flow diversion and its control in the open channels. Attempts have been made to study flow over different shapes of normal weirs, side weirs and oblique weirs. This paper is connected with the development of the discharge coefficient measurement. In the present study four different weirs in different height are considered for validation purposes. The higher weir helped to improve discharge capacity. At the end, using experimental data an equation to predict discharge coefficient based on trial and error was extracted.

full textEstimation of Discharge over the Submerged Compound Sharp-Crested Weir using Artificial Neural Networks and Genetic Programming
Truncated sharp crested weirs are used to measure flow rate and control upstream water surface in irrigation canals and laboratory flumes. The main advantages of such weirs are ease of construction and capability of measuring a wide range of flows with sufficient accuracy. Artificial neural networks (ANNs) and genetic programming (GP) have recently been used for estimation of hydraulic data. In...

Weirs, as overflow structures, are extensively used for the measurement of flow, its diversion and control in the open canals. Labyrinth weir due to more effective length than conventional weirs, allows passing more discharge in narrow canals. Determination the design criteria for the practical application of these weirs need more investigation. Weir angle and its position relative to the flow ...
