The natural scarcity of water in arid and semiarid regions, aggravated by man-made factors, makes it difficult to achieve a reliable water resources supply. Communities in these areas pay the price for thousands of years of water manipulation.
Presenting important insight into the complexities of arid region hydrology, Engineering Hydrology of Arid and Semi-Arid Regions explores the key components for formulating and implementing integrated management approaches in catchment (wadi) systems.
The book introduces the engineering hydrology of arid and semi-arid regions, covering meteorological processes and hydrology. The author discusses precipitation and precipitation losses, catchment characteristics, and runoff estimation methods. He also examines streamflow measurements and hydrographs, flood routing, and groundwater hydrology, including the basic equations of groundwater flow and analytic solutions describing flow aquifers, pumping tests, and salt water intrusion. Building on this foundation, the book then delineates sediment yield in watersheds and streams and the design of hydraulic structures for protection and management of water resources systems. It includes case studies, conversion tables, and modeling software.
During the last two decades, research efforts and networking have enhanced the state of knowledge about arid and semi-arid areas, especially watershed and catchment systems. Pulling this information together into a comprehensive resource, this book provides a better understanding of wadi hydrology, capacity-building processes, water education and training, and institutional development. This understanding can then be used to select the appropriate tools to support water management and optimize the sustainable use of water resources.

As global society confronts the challenges of diminishing resources, ecological degradation, and climate change, engineers play a crucial role designing and building technologies and products that fulfil our needs for utility and sustainability.
The Handbook of Sustainable Engineering equips readers with the context and the best practices derived from both academic research and practical examples of successful implementations of sustainable technical solutions. The handbook’s content revolves around the two themes, new ways of thinking and new business models, including sustainable production, products, service systems and consumption while addressing key assets based on new materials, optimized resource management, and new energy sources. Contributions reflect a focus on state-of-the art insights into employing smart materials, recycling e-waste, water utilization, solar cells, product lifecycles, transportation and reverse manufacturing. Supportive of this, underlying issues such as engineering education, consumer behaviour and the regulatory climate complete the handbook’s comprehensive treatment of the problems and most promising solutions.
"The efficient utilization of energy, sustainable use of natural resources, and large-scale adoption of sustainable technologies is the key to a sustainable future. The Handbook of Sustainable Engineering provides tools that will help us achieve these goals".
Nobel Prize Winner Dr. R.K. Pauchauri, Chairman, UN Intergovernmental Panel on Climate Change

Author: Phillip L. Gould | Size: 13 MB | Format:PDF | Quality:Unspecified | Publisher: Springer | Year: reprint of the original 1st ed. 1988 edition (September 21, 2011) | pages: 501 | ISBN: 146128340X
The study ofthree-dimensional continua has been a traditional part of graduate education in solid mechanics for some time. With rational simplifications to the three-dimensional theory of elasticity, the engineering theories of medium-thin plates and of thin shells may be derived and applied to a large class of engi neering structures distinguished by a characteristically small dimension in one direction. Often, these theories are developed somewhat independently due to their distinctive geometrical and load-resistance characteristics. On the other hand, the two systems share a common basis and might be unified under the classification of Surface Structures after the German term Fliichentragwerke. This common basis is fully exploited in this book. A substantial portion of many traditional approaches to this subject has been devoted to constructing classical and approximate solutions to the governing equations of the system in order to proceed with applications. Within the context of analytical, as opposed to numerical, approaches, the limited general ity of many such solutions has been a formidable obstacle to applications involving complex geometry, material properties, and/or loading. It is now relatively routine to obtain computer-based solutions to quite complicated situations. However, the choice of the proper problem to solve through the selection of the mathematical model remains a human rather than a machine task and requires a basis in the theory of the subject.
