Flow in a triangular open channel with hydraulic jump

Abstract

Mathematical model for dredging a triangular open channel with hydraulic jump is developed using the method of successive approximation. Applying the model to a numerical example new parameters of the new (excavated) channel are determined and compared with those of the original channel. Another feature of the work is the application of our model in Bernoulli’s equation which leads to the energy dissipated in the jump for both the original and new channel. Based on this, other parameters like jump efficiency, relative energy loss, power loss and height of the jump are also determined in the two channels and compared.
