Transport of sediment influences to a great extent the sustainability of an irrigation system. Unwanted erosion or deposition will not only increase maintenance costs, but may also lead to unfair and inadequate distribution of irrigation water. Proper knowledge of the behaviour and transport of sediment will help to plan efficient and reliable water delivery schedules, to have a controlled deposition of sediments, to estimate and arrange maintenance activities, etc. The main aim of these lecture notes is to present a detailed analysis and physical and mathematical descriptions of the behaviour of sediment transport in irrigation canals and to describe a mathematical model that predicts the sediment transport, deposition and entrainment rate for various flow conditions and sediment inputs. The model is typically suited for the simulation of sediment transport under the particular conditions of irrigation canals where the flow and sediment transport are strongly determined by the operation of the flow control structures.The lecture notes will contribute to an improved understanding of the behaviour of sediments in irrigation canals. They will also help to decide on water delivery plans to evaluate design alternatives and to achieve an adequate and reliable water supply to the farmers.Depeweg, Herman is the author of 'New Approach of Sedimenttransport in the Design and Operation of Irrigation Canals ', published 2007 under ISBN 9780415430654 and ISBN 0415430658.
