Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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]

Book Description
The Special Issue on Advances in Water Distribution Networks (WDNs) explores four important topics of research in the framework of WDNs, namely simulation and optimization modelling, topology and partitioning, water quality, and service effectiveness. With regard to the first topic, the following aspects are addressed: pressure-driven formulations, algorithms for the optimal location of control valves to minimize leakage, the benefits of water discharge prediction for the remote real time control of valves, and transients generated by pumps operating as turbines. In the context of the second topic, a topological taxonomy of WDNs is presented, and partitioning methods for the creation of district metered areas are compared. In relation to the third topic, the vulnerability to trihalomethane is assessed, and a statistical optimization model to minimize heavy metal releases is presented. Finally, the fourth topic focusses on the estimation of non-revenue water, including leakage and unauthorized consumption, and on the assessment of service under intermittent supply conditions.
