Book Description
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Book Description
Prepared by the Task Committee on Recommendations for Standards in Hydraulics of the Hydraulics Division of ASCE. This report investigates whether standards or guides are useful to hydraulic engineers and whether additional standards or guides should be prepared. The results of a questionnaire indicate that most hydraulic engineers are not familiar with the procedures used to develop standards or with existing national or international standards. However, responses to the questionnaire show that hydraulic engineers welcome guides or standards as long as some flexibility to use engineering judgment for site specific conditions is allowed. The report recommends that guidelines or consensus standards be developed in the following areas: application of one-dimensional surface water computer programs of the HEC-2 type; prediction of scour at bridge piers; design of pump intakes and sumps; and calculations of friction and form losses in closed conduits. Annotated lists of standards and guidelines produced in the United States and abroad are included.

Book Description
For more than 25 years, the multiple editions of Hydrology & Hydraulic Systems have set the standard for a comprehensive, authoritative treatment of the quantitative elements of water resources development. The latest edition extends this tradition of excellence in a thoroughly revised volume that reflects the current state of practice in the field of hydrology. Widely praised for its direct and concise presentation, practical orientation, and wealth of example problems, Hydrology & Hydraulic Systems presents fundamental theories and concepts balanced with excellent coverage of engineering applications and design. The Fourth Edition features a major revision of the chapter on distribution systems, as well as a new chapter on the application of remote sensing and computer modeling to hydrology. Outstanding features of the Fourth Edition include . . . • More than 350 illustrations and 200 tables • More than 225 fully solved examples, both in FPS and SI units • Fully worked-out examples of design projects with realistic data • More than 500 end-of-chapter problems for assignment • Discussion of statistical procedures for groundwater monitoring in accordance with the EPA’s Unified Guidance • Detailed treatment of hydrologic field investigations and analytical procedures for data assessment, including the USGS acoustic Doppler current profiler (ADCP) approach • Thorough coverage of theory and design of loose-boundary channels, including the latest concept of combining the regime theory and the power function laws

Book Description
This unique volume presents up-to-date information and the latest research findings on unconventional water resources in Egypt and their connections to agriculture. It investigates how to cope with the severe shortage of water and how to improve the irrigation system’s efficiency. The main aspects addressed include: · History of drainage and drainage projects in Egypt · Towards the integration of irrigation and drainage water · Assessment of drainage systems and environmental impact assessment of irrigation projects · Maximizing the reuse of agricultural drainage water and agricultural waste to improve irrigation efficiency · Developing alternative water resources, such as desalination, for greenhouses · Drainage water quality assessment, microbial hazards and improvement of green and cost-effective technologies for treatment of agricultural drainage water and wastewater for reuse in irrigation · Towards the sustainable reuse of water resources in Egypt · Options for securing water resources in Egypt, and challenges and opportunities for policy planners This book and the companion volume Conventional Water Resources and Agriculture in Egypt are vital resources for researchers, environmental managers and water policy planners – and for all those seeking information on wastewater reuse, green and cost-effective technologies for improving water quality.

Book Description
Irrigated agriculture and the use of water resources in agriculture face the challenges of sustainable development. Research has advanced our knowledge of water use by crops, soil-water-solutes interactions, and the engineering and managerial tools needed to mobilize, convey, distribute, control and apply water for agricultural production. However, the achievements booked in user practice have revealed the need for new developments in the areas of resource conservation, control of environmental and health impacts, modernisation of technologies and management, economic viability and the social acceptance of changes. The contributions to Sustainability of Irrigated Agriculture cover most of the relevant disciplines. Besides its multidisciplinarity, the different origins, experience, backgrounds and practices of the authors provide a wide, in-depth analysis of the various aspects of water resource utilization in agriculture. The papers review scientific, technical and managerial aspects, highlighting the main problems, issues and future developments. The book covers the different aspects of sustainability, including environmental, technical, economic, institutional and social ones. Advances in irrigation science and engineering are dealt with, both on- and off-farm. Special attention is paid to the different components of water quality management, to the transfer of technology, and to capacity building.
