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.

This book was released on 2018-09-10 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: The management of a canal starts from setting the demand delivery accurately taking into account the crops necessities during the irrigation cycle and establishing the gate trajectories for controlling the canal in each time step. In an ideal case; the system would be controlled but someone could introduce a disturbance in the canal which could deviated the real canal state from the desired canal state. In that circumstance; it would be necessary a feedback controller which could aid the watermaster to restore the desired canal state. In order to fulfill this objective; we define an overall control diagrams scheme which splits the management of the canal control in different blocks and each of these blocks is represented by a particular algorithm. The algorithms developed and tested for us in this book are the CSI and GoRoSoBo algorithms Presents the management of a canal Explains the system of the real and desired canal Defines a global control scheme to master the canal Develops and test the CSI and GoRoSoBo algorithms

This book was released on 2021-02-26 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Waste management in Lebanon is a significant issue anticipating cascading and spill-over effect on livelihood, environment and agriculture. North Lebanon has been experiencing population growth spurts due to humanitarian crises in neighbouring countries that contributes to the urgency of finding sustainable solutions. Adequate delivery of response measures is beyond the capacities of local authorities. Consequently, waste crisis has reached its historical peaks. It is unlikely that upcoming years can bring radical shifts related to the trends in rapidly increasing waste generation. However, the seemingly uncontrollable mechanisms should not lead to inaction, but concentrated efforts should be stepped up to eliminate harmful consequences. The project “Rehabilitation and waste management of El-Bared Canal Irrigation System to reduce source-to-sea pollution and improve livelihoods in the Akkar Region of Lebanon”, financed by the Government of Norway, has been formulated to ensure minimal discharges of waste from El-Bared System to the Mediterranean Sea, thus improving the livelihoods of the people depending on the system through irrigation canal system rehabilitation, solid waste disposal, and improved agricultural output and job creation. Applying a pilot approach, the project mainly focuses on Akkar irrigation scheme to introduce both hard investment and soft measures in response to the waste crisis. Following a multi-criteria assessment approach, the current report maps waste removal technologies and provides recommendations on their functions and suitability in the context of the target area. Based on broader understanding of the feasibility, it helps come to a decision on technology selection.

Download or read book By the Irrigation Canals of Babylon written by John J. Ahn and published by Bloomsbury Publishing USA. This book was released on 2012-02-18 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work assembles some of the finest scholars who have contributed to study and examination of the impact of the exile in biblical literature. Past, present, and future scholars examining the 6th century B.C.E. through historical and archeological (including paleoclimatology), literary, and the social sciences have been assembled. Approximately twelve papers from among the twenty papers presented over the four sessions (parallel to a sizable conference on the exile) will be represented in this volume. The book will be organized in a traditional history of scholarship manner, i.e., moving from historical to sociological. It should be noted that within each subcategory, there is a forward progressive movement from a traditional starting point (Klein, Olson, Wilson) ending at the progressive or cutting edge (Beck, Ahn). Jill Middlemas will open the volume with and introductory essay. John Ahn will close off the volume by pointing to the field of "forced migration studies" as a way to help better define and demarcate the import of 597, 587, and 582.

Download or read book Fish Production in Irrigation Canals written by Theresa A. Redding and published by Food & Agriculture Org.. This book was released on 1991 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication reviews the potential for fisheries production from irrigation canals. It deals with the subject under the following major headings: engineering aspects of irrigation systems; factors limiting fish production in canals; weed growth and associated problems in irrigation canals. Cage culture in irrigation canals is presented in case studies for Indonesia, Egypt and Thailand, and pen culture in China. Both cage and pen culture are considered to be the most suitable forms of aquaculture in irrigation canals. Fish can be profitably and successfully reared in irrigation canals to control unwanted aquatic weed growth, and there is some potential for the use of fish to control vectors and hosts of waterborne diseases. Amongst the constraints, levels of pesticides in fish tissues cultured in irrigation systems could be a problem in the development of foodfish production in irrigation canals. The major constraint to aquaculture development in such systems is that a continuous, preferably constant, flow of water is required throughout the culture period and this is not available in many irrigation systems.
Download or read book Canal Irrigation in Prehistoric Mexico written by William E. Doolittle and published by University of Texas Press. This book was released on 2011-03-23 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prehistoric farmers in Mexico invented irrigation, developed it into a science, and used it widely. Indeed, many of the canal systems still in use in Mexico today were originally begun well before the discovery of the New World. In this comprehensive study, William E. Doolittle synthesizes and extensively analyzes all that is currently known about the development and use of irrigation technology in prehistoric Mexico from about 1200 B.C. until the Spanish conquest in the sixteenth century A.D. Unlike authors of previous studies who have focused on the political, economic, and social implications of irrigation, Doolittle considers it in a developmental context. He examines virtually all the known systems, from small canals that diverted runoff from ephemeral mountain streams to elaborate networks that involved numerous large canals to irrigate broad valley floors with water from perennial rivers. Throughout the discussion, he gives special emphasis to the technological elaborations that distinguish each system from its predecessors. He also traces the spread of canal technology into and through different ecological settings. This research substantially clarifies the relationship between irrigation technology in Mexico and the American Southwest and argues persuasively that much of the technology that has been attributed to the Spaniards was actually developed in Mexico by indigenous people. These findings will be important not only for archaeologists working in this area but also for geographers, historians, and engineers interested in agriculture, technology, and arid lands.
