IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Computation of bed shear stresses in natural torrential channels using smooth particle hydrodynamics

mountain torrents is very complex and typically characterized by non-linearity due to high roughness,
steepness, wide range in torrent sediment sizes, presence of large woody debris, etc. Such flow is highly turbulent and
difficult to describe with Eulerian grid-based methods. Smoothed Particle Hydrodynamics (SPH) method is a suitable
Lagrangian method for modelling flow in typically rough and steep torrential streams. This paper introduces a new
equation for the bed shear stresses using SPH. These new technique was verified and calibrated through two case
studies (a. in a channel and b. in a natural torrential channel). Computed bed shear stresses in channel using SPH were
also compared with computed bed shear stresses using other conventional method.Form Required :
