Book Description
Research on reservoir sedimentation in recent years has been aimed mainly at water resources projects in developing countries. These countries, especially in Africa, often have to cope with long droughts, flash floods and severe erosion problems. Large reservoir capacities are required to capture water provided by flash floods so as to ensure the supply of water in periods of drought. The problem arising however is that these floods, due to their tremendous stream power, carry enormous volumes of sediment which, due to the size of reservoirs, are virtually deposited in toto in the reservoir basin, leading to fast deterioration of a costly investment. Accurate forecasting of reservoir behaviour is therefore of the utmost importance.This book fills a gap in current literature by providing in one volume comprehensive coverage of techniques required to practically investigate the effects sediment deposition in reservoirs has on the viability of water resources projects. Current techniques for practically estimating sediment yield from catchments, estimating the volume of sediment expected to deposit in reservoirs, predicting sediment distribution and calculating scour downstream of reservoirs are evaluated and presented. The liberal use of diagrams and graphs to explain the various techniques enhances understanding and makes practical application simple. A major feature of the book is the application of stream power theory to explain the process of reservoir sedimentation and to develop four new methods for predicting sediment distribution in reservoirs.The book is primarily directed at practising engineers involved in the planning and design of water resources projects and at post-graduate students interested in this field of study.

Book Description
This book provides a comprehensive overview of the Yangtze River system and its water resources development and management. From the perspectives of geology, hydrology, zoology, ecology, it discusses the Yangtze River’s geological history and aquatic environments, analyses the endangered species along the river basin, and reviews the effects of human hydrolytic activities on its ecosystem. By studying the history of Yangtze River system and its water resources development, it provides insights into the effects of evolution and human activities on the ecosystem of its basin, and offers strategic thoughts on conservation and sustainable development of the Yangtze River. Written by an author with extensive experience in the field, this book is an invaluable reference resource for researchers interested in the Yangtze River.

Book Description
The Yangtze River estuary is a system where geological, biological, and socioeconomic processes actively interplay. The Yangtze River carries about 5 billion tons of sediment to the estuary from upstream each year, providing rich substrates for biological activities and alluvial processes. An exotic plant species, Spartina alterniflora was intentionally introduced to the region in 1979, and has aggressively invaded the Yangtze River estuary and coastal China. The biological invasion alters plant and animal biodiversity and ecosystem processes. In addition, the Yangtze River estuary is close to Shanghai, one of the most economically active cities in China and the world. Fast economic development and social transformation exert great pressure to exploit resources in the estuary. In the last few decades, scientists from several leading universities in China have conducted research on many of geological, biological, and socioeconomic processes. An increasing number of papers have been published in international journals. This volume comprehensively synthesizes the lessons learned from various groups. This text not only provides a new example of ecosystem studies on estuary systems, but will also serve as a milestone to promote the management of this important region that will produce global impacts. Moreover, the book can be used as a reference book for ecological research in estuarine ecosystems of major rivers, such as the Mississippi and Amazon Rivers.

Book Description
This book is highly informative and carefully presented, providing scientific insights into the flood resources utilization in the Yangtze River Basin both for scholars and decision-makers. The book is for the purpose of analyzing the potential utilization of flood resources in the Yangtze River Basin and exploring effective ways to put forward the countermeasures against the risks. Major objectives of this book include: (1) revealing the characteristics of the inflow and the sediment variation in the upper reaches of the Yangtze River, quantitatively evaluating the potential utilization of the flood resources in the Yangtze River and demonstrating the feasibility of its utilization in the Basin; (2) proposing the necessity and feasibility of utilizing the flood resources by the Three Gorges Project; (3) shedding new light on the characteristics of the flood resources, presenting different methods of flood resources utilization in different regions over the Basin and raising the overall risk-optimized strategies of the flood resources utilization in the Yangtze River; (4) analyzing the risk of flood resources utilization for the Three Gorges Project regarding flood control, sediment, ecology, etc., and putting forward the risk-optimized countermeasures of flood resources utilization for the Three Gorges Project.

Book Description
The evolution of land space demonstrates the shift of land use types from natural and semi-natural land (e.g., forest land and cropland) to built-up land, altering ecosystem cycling patterns and leading to degradation of ecosystem services in terms of regulation, provisioning and support. At the same time, production and living space crowding out ecological space brings high potential threats, such as soil erosion, forest productivity decline and habitat fragmentation. Accordingly, in response to the problems of imbalanced territorial space development, inefficient resource utilization and ecological environment degradation, how to improve the diversity, stability and sustainability of ecosystems is an urgent issue to promote modernization and green development in the new era of territorial space evolution.
