Abstract

This thesis discusses the removal of cohesionless sediments by siphoning. A significant part of this study involves the analysis of equilibrium scour hole dimensions under different siphon flow characteristics. Scour holes of the sediments were formed by a siphon tube of three different sizes (9.65, 13.86 and 20.4 mm) positioned vertically at different positions relative to the surface of the sand bed. A total of 174 tests were performed, where the position of the tube ranged from 101.6 mm below the original bed to 6.4 mm above it. The latter part of the study investigates the heights for critical and general movement of the sediment particles. Initially, dimensional analysis was used to examine all length parameters relating the equilibrium scour hole dimensions and the heights for critical and general movements with the characteristics of the flow through the siphon tube. After using dimensional analysis, an effort was made using theory to determine what other parameters might affect the scouring process. This analysis is based on the threshold movement of a sediment particle moved by the viscous shear stress in a laminar boundary layer.
