The purpose of the investigation described herein is to perform basic research on
sediment sluicing as a method to restore or maintain reservoir storage capacity. The
objectives are a) to understand the nature of reservoir aggradation and degradation in
simple cases usmg laboratory models, and b) to develop a one-dimensional mathematical
model to describe the physical processes involved.
The remainder of the thesis is organized as follows: first a literature review
describes the process of reservoir sedimentation in detail, including methods of
preserving reservoir capacity and sediment sluicing effectiveness. The review also
discusses experimental and mathematical modeling approaches used in past reservoir
sedimentation investigations. The experiments are then described, including the setup,
procedure, and results. Development and testing of the numerical model are then
presented including an illustration of a field-scale case. This is followed by the
development of equations for the bed slope and elevation of rectangular channels of
Hotchkiss, Rollin Hull.
