This study contributes to the understanding of the mechanisms and processes of sand bypassing in artificial and non-artificial coastal environments through a numerical modelling study. Sand bypassing processes in general is a relevant but poorly understood topic. This study attempts to link the theory and physics of sand bypassing processes which is significantly important in definition of coastal sedimentary budget. The main question is how can we model sand bypassing processes and whether the modelled sand bypassing processes represent the actual sand bypassing processes. In this study, it is shown that a process-based model can be used to simulate the processes of sand bypassing around groyne and headland structures. Both hypothetical and real case studies were successfully developed. Results comparisons were made among analytical models, empirical models and field data measurements. In general, the process-based model can produce reasonable results. In summary, through numerical modelling this study reveals the importance of understanding coastal processes and the role of geological controls in governing headland sand bypassing processes and embayed beach morphodynamics. The morphological model developed in this study is useful to increase understanding of the natural sand distribution patterns due to combination of engineering efforts and natural coastal processes.

Revised and updated, this second edition of Design of Hydraulic Gates maintains the same goal as the original: to be used as a textbook and a manual of design of gates, presenting the main aspects of design, manufacture, installation and operation of hydraulic gates, while introducing new products, technologies and calculation procedures. This edition included new chapters on intake gates and trashrack design, highlighting the aspects of safety, operational and maintenance procedures. To improve the strength against structural failure of intake trashracks, the author proposes a series of rigid calculation assumptions, design parameters and manufacturing procedures, which will certainly result in safer trashracks. Some 340 drawings and photographs, 82 tables, 107 references and 23 worked examples help the reader to understand the basic concepts and calculation methods presented.

He was also directly involved in the licensing and regulating of small dams in Australia.
Water demand in southern Africa continues to rise, as urban areas expand and as agricultural water demand rises to meet the millennium development food security goals. Water resource availability in the northern Limpopo Basin has declined over the last 30 years, and will decline further under climate change. In this study, water resources modelling is used to quantify the effect of water resources strategies and climatic conditions on water resources availability. This is coupled with water balance modelling to evaluate the potential of alluvial aquifers, which form the beds of sand rivers. The greatest benefit for the least impact comes from strategies providing for better land and soil/water management, such as changing from maize to small grains, production of livestock fodder and conservation agriculture. Small dams are a key resource to rural communities, and change to Multiple Use Systems through abstraction of water for irrigation has clear benefits locally. There is also great potential for the exploitation of alluvial aquifers for water supply. Better management of existing large dams, together with conjunctive use of alluvial groundwater and several reservoirs could increase productive use of water and significantly improve livelihoods without the construction of new reservoirs.
This well-established text book fills the gap between the general
texts on fluid mechanics and the highly specialised volumes on

Read a free excerpt here! American engineers have done astounding things to bend the Mississippi River to their will: forcing one of its tributaries to flow uphill, transforming over a thousand miles of roiling currents into a placid staircase of water, and wresting the lower half of the river apart from its floodplain. American law has aided and abetted these feats. But despite our best efforts, so-called "natural disasters" continue to strike the Mississippi basin, as raging floodwaters decimate waterfront communities and abandoned towns literally crumble into the Gulf of Mexico. In some places, only the tombstones remain, leaning at odd angles as the underlying soil erodes away. Mississippi River Tragedies reveals that it is seductively deceptive-but horribly misleading-to call such catastrophes "natural." Authors Christine A. Klein and Sandra B. Zellmer present a sympathetic account of the human dreams, pride, and foibles that got us to this point, weaving together engaging historical narratives and accessible law stories drawn from actual courtroom dramas. The authors deftly uncover the larger story of how the law reflects and even amplifies our ambivalent attitude toward nature-simultaneously revering wild rivers and places for what they are, while working feverishly to change them into something else. Despite their sobering revelations, the authors' final message is one of hope. Although the acknowledgement of human responsibility for unnatural disasters can lead to blame, guilt, and liability, it can also prod us to confront the consequences of our actions, leading to a liberating sense of possibility and to the knowledge necessary to avoid future disasters.
Along with windstorms, floods are the most common and widespread of all natural disasters. Although they can often be predicted, they cause loss of life, damage and destruction, as many urban communities are located near coasts and rivers. In terms of victims, floods are responsible for more than half the deaths caused by natural catastrophes. As flood events appear to be rapidly increasing world-wide, an advanced and universal approach to urban flooding and how to manage will help reduce flood impact. This textbook integrates expertise from disciplines such as hydrology, sociology, architecture, urban design, construction and water resources engineering. The subject is approached from an international perspective and case studies, exercises, expert advice and literature recommendations are included to support the theory and illustrations. Developed by a team of specialists, this volume is intended for urban flood management education of hydrology, geography, civil and environmental engineering, and management students at university level. Moreover, professionals will find this book useful as a reference. More information on flood resilience and urban flood management can be found at www.floodresiliencegroup.org For a preview, please go to http: //issuu.com/crcpress/docs/urban_flood_management

The book supplies the knowledge tools necessary to analyze and design economical and properly performing conveyance systems. Thus not only is the book useful for graduate students, but it also provides professional engineers the expertise and knowledge to design well performing and economical channel systems.
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.
