Available in PDF, EPUB and Kindle. Book excerpt: Sediment transport in irrigation canals 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, unreliable and unequitable distribution of irrigation water to the end users. Proper knowledge of the characteristics, including behaviour and transport of sediment will help to design irrigation systems, plan effi cient 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 sediment transport in irrigation canals and to describe the mathematical model SETRIC that predicts the sediment transport, deposition and entrainment rate as function of time and place for various flow conditions and sediment inputs. The model is typically suited for the simulation of sediment transport under the particular conditions of non-wide 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 the appropriate design of the system, the water delivery plans, to evaluate design alternatives and to achieve an adequate and reliable water supply to the farmers.

Available in PDF, EPUB and Kindle. Book excerpt: An irrigation canal is a waterway, often man-made or enhanced, built for the purpose of carrying water from a source such as a lake, river, or stream, to soil used for farming or landscaping. The engineering concept of efficiency at different levels of a canal system is important for planning, designing and even operating a canal irrigation system.

Available in PDF, EPUB and Kindle. Book excerpt: Assessment of freshwater sediments can determine whether chemical concentrations are sufficient to cause adverse effects on aquatic organisms or organisms higher in the food chain, including humans. This book presents methods for assessing sediments and includes an integration of physical, chemical, and biological information. It examines the elements of quality assurance and control programs, considerations for the conduct of field surveys, screening-level analyses, chemical analyses, toxicity tests for assessing biological impacts, assessments of benthic invertebrate community structure, surveys of fish tumors and abnormalities, and data presentation and interpretation techniques.

Download or read book Progress in River Engineering and Hydraulic Structures written by Mohammed Al-Baghdadi and published by Createspace Independent Publishing Platform. This book was released on 2018-02-09 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is the essential element that all life-forms on our planet are dependent on. It is impossible to assess its value because it is equal to the life itself. Humans realized this fact long time ago and they always endeavored to control and manage water resources as they were afflicted by the drought and flood events throughout history. Therefore, the engineering of water resources and hydraulic structures is as old as the human civilization. The earliest known engineered irrigation system was developed in ancient Mesopotamia (Iraq); an advanced system of dikes, dams and canals was built for the purpose of irrigation and flood control. The main water sources for this system were the rivers Euphrates and Tigris. During plant growing seasons, the flow of water was properly regulated. Each farmer was allowed a certain amount of water, which was diverted from the canal into an irrigation ditch. The oldest known engineering plan of such an irrigation system has been documented on some unique and ancient clay tablet which has been discovered in Babylonia (belonging to 1684-1647 BC). It shows a map of canals with cuneiform scripts providing details about names, lengths, widths and depths of the canals and the volume of sediment to be dredged. Mesopotamians have acquired the expertise of maintaining their irrigation system over thousands of years. This contribution was a major step toward the modernization of humanity. The Water Research Center (located in Iraq), which is dedicated to the exchange of knowledge and technology in the water sector, has been inspired by those ancient engineers, hence published this book series entitled "Progress in River Engineering & Hydraulic Structures". It is intended to be a worldwide platform for the contemporary research in this field. Chapters of this series demonstrate the stringent need for new solutions and technologies in the subject of river engineering and hydraulic structures. The chapters cover a wide range of problems related to river regime and training works, performance of different kinds of hydraulic structures and any related multidisciplinary research. We believe that through the collaboration of researchers, engineers and professionals, we can accelerate the development in these areas. The book is aimed to serve as a reference for both researchers and postgraduate students.

Download or read book Role of Sediment Transport in Operation and Maintenance of Supply and Demand Based Irrigation Canals Application to Machai Maira Branch Canals written by Sarfraz Munir and published by CRC Press. This book was released on 2011-01-27 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book is concerned with one of the methods of removing sediments from reservoirs, namely the flushing of sediments through purpose built outlet works within the dam. This technique can be applied to existing dams, with adaptation of the engineering works, and to new dams. The book gives practical guidance on the necessary hydrological, hydraulic, sedimentological and topographical features for successful flushing.In this book the author draws together his wealth of experience of working in this field.
