DOWNLOAD EBOOKFrom considerations of energy balance and of mechanical equilibrium, a mathematical expression is derived relating the rates of sediment transport as bedload and as suspended load to the expenditure of power by a statistically steady flow of water.

DOWNLOAD EBOOKThis work describes the role of sediment transport in the operation and maintenance of demand-based downstream controlled irrigation canals. Sediment deposition in these irrigation canals severely affects the operation of the automatic flow control system. The book also discusses sediment transport modelling in irrigation canals. A simplified 1-D mathematical model SETRIC (SEdiment TRansport in Irrigation Canals) has been improved with the inclusion of downstream control component for the downstream controlled irrigation canals. Based on field measurements and sediment transport modelling, a number of approaches have been proposed for sediment management in such irrigation canals by improvement in their design and operation. This book will be of interest to Irrigation Engineers and Managers, Hydraulic Engineers, Water Resources Engineers and Managers, Civil Engineers, and Agricultural Engineers.

DOWNLOAD EBOOKThis textbook discusses the fundamental principles of sediment transport in the geophysical context of rivers. It is intended as both a course textbook and as a guide for the practical engineer. It begins begin by describing phenomena such as bed load and suspension transport from a classical perspective. Concepts from turbulent flow regime are introduced to address the limitations of the classical approach to various aspects of sediment transport.

DOWNLOAD EBOOKWhile sediment transport in steady uniform flows has been studied extensively, significant amount of sediment movement occurs in unsteady flows. A nonhomogeneous discrete-time Markov chain model is proposed in this study to quantify the bedload discharges under unsteady flow conditions. The proposed two-state Markovian bedload model can be further extended to a three-state sediment transport model by adding a suspended load layer as the third state. As opposed to the homogenous two-state Markovian bedload models in literature, the proposed nonhomogeneous Markov chain model ensures the transition probabilities are really time dependent as they are function of local flow conditions. Furthermore, a full model of both the bedload and the suspended load that does not require an equilibrium sediment transport assumption can be achieved by adding a third layer (the suspended load layer) to the existing two-state model. The proposed stochastic sediment transport model can be used to calculate sediment discharges for an arbitrary size fraction of nonuniform sediment. Sediment transport processes vary at a variety of time scales - from seconds, hours, days to months and years. Recognizing the importance of different varying time scales in the fluvial processes of sediment transport, the Hilbert-Huang Transform method (HHT) is introduced to the field of sediment transport for the time scale analysis. The HHT uses the Empirical Mode Decomposition (EMD) method to decompose a time series into a collection of the Intrinsic Mode Functions (IMFs), and uses the Hilbert Spectral Analysis (HSA) to obtain instantaneous frequency data. The EMD extracts the variability of data with different time scales, and improves the analysis of data series. The HSA can display the succession of time varying time scales,which cannot be captured by the often-used Fast Fourier Transform (FFT) method. This study is one of the earlier attempts to introduce the state-of-the-art data analysis technique for the multiple time sales analysis of sediment transport processes. Three practical applications of the HHT method for data analysis of both suspended sediment and bedload transport time series are presented.

DOWNLOAD EBOOKThe transport of sediment greatly influences the sustainability of an irrigation system. Erosion and deposition not only increase maintenance costs, but may result in an inequitable and inadequate distribution of irrigation water. Understanding the behaviour and transport of sediment allows efficient planning and reliable water delivery schedules,
