Available in PDF, EPUB and Kindle. Book excerpt: Design of water distribution networks is traditionally based on trial-and-approach in which the designer assumes, based on experience and judgment, sizes of different elements and successively modifies them until a network with satisfactory hydraulic performance is obtained. This text covers: Essential hydraulic, economic optimization principles. Theory is developed gradually for optimal design of simple, single-source branched networks subjected to single loading to complex, multiple-source looped networks subjected to multiple loading. Strengthening and expansion of existing networks and also reliability-based design. Several illustrative examples enabling the reader to apply them in practice- approximately 100 line drawings.

This book was released on 2007 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this paper is to facilitate the planning and design of land drainage systems for sound land and water management for engineers and other professionals. It considers the integration of technical, socio-economic and environmental factors and the need for system users' participation in the planning, design, operation and maintenance processes. The text provides guidelines for the appropriate identification of drainage problems, for the planning and design of field drainage systems (surface and subsurface) and the main drainage and disposal systems. The annexes provide more detailed information with technical background, appropriate equations, some cross-references for finding appropriate methodologies, and computer programs for calculation of extreme values, of permeability and some land drainage system parameters. --Publisher's description.

Available in PDF, EPUB and Kindle. Book excerpt: A Water distribution system connects consumers to sources of water, using hydraulic components, such as pipes, valves, and reservoirs. The engineer faced with the design of such a system, or of additions to an existing system, has to select the sizes of its components. Also he has to consider the way in which the operational components, pumps and valves, will be used to supply the required demands with adequate pressures. The network has to perform adequately under varying demand loads, hydraulic and operational conditions. Operational decisions for these loads are essentially part of the design process, since one cannot separate the so-called design decisions, i.e. the sizing of components, from the operational decisions; they are two inseparable parts of one problem. This work has therefore presented a method for optimizing the design of a water distribution network system using pipe diameter as decision variable under the required demand loading and hydraulic conditions. It has been established that increasing the minimum pressure will lead to the reduction in the required pipe diameter which will in turn reduce the cost of installation. The modelling approach developed can be used by engineers and planners to obtain economical pipe sizes for a network designed to serve newly planned layouts.

This book was released on 2000 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the strong competition that is arising for water resources the modernisation of irrigation systems is becoming a critical issue. One of the alternatives to modernisation is the use of pressurised systems to replace part of the existing networks. This publication analyses the performance of pressurised irrigation systems operating on demand, and provides revised criteria for the design of such irrigation networks. For this purpose, new approaches and a computer program have been developed. The program has been tested in several field situations in the Mediterranean Basin and has demonstrated its usefulness not only by quickly identifying weak points in irrigation networks but also by identifying the power requirements of pumping stations needed to satisfy varying demand situations.

This book was released on 2013 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The burdensome capital cost of urban water distribution systems demands the use of efficient optimization methods capable of finding a relatively inexpensive design that guarantees a minimum functionality under all conditions of operation. The combinatorial and nonlinear nature of the optimization problem involved accepts no definitive method of solution. Adaptive search methods are well fitted for this type of problem (to which more formal methods cannot be applied), but their computational requirements demand the development and implementation of additional heuristics to find a satisfactory solution. This work seeks to employ adaptive search methods to enhance the search process used to find the optimal design of any water distribution system. A first study presented here introduces post-optimization heuristics that analyze the best design obtained by a genetic algorithm--arguably the most popular adaptive search method--and perform an ordered local search to maximize further cost savings. When used to analyze the best design found by a genetic algorithm, the proposed post-optimization heuristics method successfully achieved additional cost savings that the genetic algorithm failed to detect after an exhaustive search. The second study herein explores various ways to improve artificial neural networks employed as fast estimators of computationally intensive constraints. The study presents a new methodology for generating any large set of water supply networks to be used for the training of artificial neural networks. This dataset incorporates several distribution networks in the vicinity of the search space in which the genetic algorithm is expected to focus its search. The incorporation of these networks improved the accuracy of artificial neural networks trained with such a dataset. These neural networks consistently showed a lower margin of error than their counterparts trained with conventional training datasets populated by randomly generated distribution networks.

This book was released on 2024-05-22 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: FAO's Irrigation and Drainage Paper No. [Author] 63 introduced the MASSCOTE methodology in 2007, tailored for modernizing large-scale canal irrigation systems. [Author] With global interest shifting towards pressurized pipe systems, particularly in water-scarce regions, the need for a similar methodology became apparent. [Author] Pressurized systems offer advantages like on-demand irrigation, reduced water wastage, and environmental impact. [Author] However, they require complex management due to changing water demands. [Author] To address this, FAO developed the MASSPRES approach, building on MASSCOTE's principles. [Author] MASSPRES aims to assess and enhance the performance of pressurized irrigation schemes, introducing steps like the Rapid Appraisal Procedure (RAP) for system mapping. [Author] It offers innovative methods for evaluating pressures and discharges at farm hydrants under various operating conditions, replacing earlier statistical analysis approaches. [Author] MASSPRES incorporates indicators for capacity, reliability, distribution equity, sensitivity to change, and perturbation risks into user-friendly software. [Author] Practical examples from Egypt, Italy, Spain, and Tunisia showcase its effectiveness. [Author] As governments seek to improve water and food production amidst increasing water scarcity, adopting technologies like pressurized irrigation becomes crucial. [Author] MASSPRES provides a systematic framework for both upgrading existing systems and designing future ones, addressing the complexities of managing pressurized irrigation efficiently. [Author]
