English Abstract

In this research an open boundary technique is developed for the numerical SPH method to simulate and characterize the flow field variables in open channels.

For this purpose the open source code 2D SPHysics is applied after being modified to satisfy the flow conditions in open channels.

The modified code is then calibrated against the experimental results gathered from experiments conducted previously on the flow over embankment dam stepped spillways.

The numerical results of this study in terms of the position of free surface flow and velocity distribution at different sections along the chute slope are close to the corresponding experimental results.

However, the new technique developed in this study still needs to be calibrated against various open channels problems to verify its applicability.
