This book was released on 2002 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fisheries in inland waters have long provided an important source of food for mankind. One way to make the use of these resources sustainable and to improve food security and livelihoods is through the development of sustainable fisheries management practices. This book is a compilation of modern knowledge on all aspects concerning the planning and construction of fishpasses as well as their monitoring for effectiveness. Emphasizing the need to take into consideration biological and behavioral characteristics of the species, it describes in detail the engineering options that are available today to make obstacles passable.--Publisher's description.

Download or read book Urban Rivers written by G. Petts and published by IWA Publishing. This book was released on 2002-03-31 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of urban development is associated with the degradation of rivers - the deterioration of water quality, increased flooding, and the loss of ecological resources. The story of urban streams and rivers is as much a social history as it is a technological one. The control of nature and exploitation of natural resources was at the heart of the industrialisation process and of advances in the co-ordination and effective administration of water-and land-management schemes. Today, new approaches to the management of urban water are a response to advances in scientific knowledge and technology, and of a new concern for quality of life. Environmental improvement and ecological restoration demonstrate confidence in an area, which can enhance economic competitiveness. Along with improvements in air quality, building stock and transport networks, the restoration of stream and river corridors can make a major contribution to the success of urban regeneration schemes. Urban Rivers provides an illustrated overview of the effects of urbanisation on the aquatic environment, potential solutions to the resulting problems, and new opportunities for the regeneration of urban streams and rivers, and of land along their corridors and of adjacent urban areas. The book is written to be accessible to a broad audience and should provide a stimulating and informative introduction to the subject for all those concerned with the urban river environment.
Download or read book River Health and Ecology in South Asia written by Bidhan Chandra Patra and published by Springer Nature. This book was released on 2021-12-01 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews recent hydrological and environmental issues resulting from human-induced water pollution practices while providing case studies on the physical, chemical, and eco-biological techniques used to mitigate the impacts of river ecosystem pollution in South Asian countries. The book demonstrates the key methods of measurement, monitoring, mapping, and modeling of river water quality and how it is impacted by pollution and incorporates contemporary geospatial technological applications for the management and sustainability of future water resources. The major topics that the book addresses are the fundamental concepts of river ecosystem health, riverine ecology and habitats, risk assessment of riverine pollution, and technology-based river pollution control strategies. The book will serve as an interdisciplinary guide for researchers, students, and GIS specialists working in various disciplines, including pollution hazards, river ecosystem restoration, water quality, remote sensing, zoology, natural resources management, and environmental geography.

Download or read book Rehabilitation of Rivers for Fish written by Ian G. Cowx and published by Food & Agriculture Org.. This book was released on 1998 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Value can be added to projects for restoring the aesthetic appeal of modified waterways at very little extra cost if the needs of the living components of the system are taken into account. This manual was prepared by the European Inland Fisheries Advisory Commission (EIFAC) to provide guidelines and techniques for the rehabilitation of rivers for fish. It is intended for the use of fisheries managers, fisheries and wildlife biologists, land and water use planners, and civil engineers working on projects involving the protection and rehabilitation of inland running waters. While the primary orientation of the manual is towards rivers of the temperate zone, the techniques described can be applied to the restoration of rivers of similar dimensions in other climatic areas.
