Book Description
This is the first book to provide a truly global synthesis of knowledge on river conservation, and will be an invaluable reference for all those concerned with strategic river planning. Throughout the world, river ecosystems frequently reflect the worst excesses of human exploitation for instance when rivers are used as repositories for waste. Recognition is growing that river management needs to move from chemical clean-up to restoring the structural damage caused by decades of river engineering. There needs to be a catchment-wide perspective if the needs of human populations, river habitats and wildlife are to reach a sustainable balance. Against this backdrop, the development of river conservation strategies has become a global imperative. This book sets out a worldwide, region-by-region overview of the science, policy and practice of river conservation. It also provides a topical review of different river settings (such as tropical/temperate; temporary/perennial; large/small) and contemporary issues in river conservation (such as classification and evaluation; environmental legislation; the role of public participation). Clearly written by leading researchers in the field, this book will be welcomed by all those working on environmental management of inland waters as well as academics, researchers, postgraduates and final year undergraduates.

Book Description
The Author Has Further Enlighted How Under Stressed Condition Fish And Other Biological Organisms Are Surviving Which Results A Progressive Decline In Fish Population And Fish Food Organism. The Book Highlites Detailed Information On Various Aspects Of The Past And Present Status Of The Ganga River System Like: High Rate Of Deforestation, Recurring Annual Slit Precipitation Indicated By High Value Of Shape Factor, Reduced Water Holding Capacity Of The River, And Its Tributaries, Low Water Flow And Its Velocity, Shifting Of River Course And Its Tributaries Resulting Information Of Ox-Bow Lakes, Mendor Loops, Dead Arms, Chars, Tals And Ruins Of Settlements, Abstraction Of Water For Agriculture, Industrial And Urban Uses, Nature Of Waste Water Disposed, Pollution Load Their Ratio With Unpolluted Water In Different States, Changes In The Physico-Chemical And Biological Parameters, Metallic And Pesticide Pollution, Bio-Accumulation Of Metals In Aquatic Life Including Fish, Fishing In Shallow Inundated Areas, (Ox-Blow Lakes, Chars Mans Etc.), Status Of Juvenile Fishery In The Total Catch, Fish Seed Resources Its Future, Breeding Grounds, Impact Of Dams And Barrages On Fishery Potential Etc. And Over All Stressed Environment And The Aquatic Life And Finally Conservation And Management Of The River System Under Existing Economic Condition. The Author Has Taken Immense Pains To Provide An Up To Date Information Of The Ganga River System On The Above Aspects In This Book.

Book Description
The book Ganga: A Scientific Study is based on an Integrated Research Programme carried out by 14 Universities located in the Ganga Basin sponsored and funded by the Envioronment Research Committee and The Ganga Project Directorate, Ministry of Environment & Forests, Government of India, New Delhi. The Ganga, one of World's major rivers, has been venerated as the holiest and is bound with countless beliefs and faiths especially in India and adjacent countries. Its water has traditionally been regarded as an inexhaustible gift of nature. Recent experiences do not, however, warrant such a complacency. The water resources are strained to a non-sustainable level due to rapid population explosion, urbanisation, development of agriculture, industry, livestock and power production in the Ganga basin. The hydrobiological quality of water has deteriorated and yet no concise, valid supporting evidence was available in a comprehensive manner covering the entire river. This book is an attempt towards this direction. For the first time a picture of the Ganga is available with its physico-chemical and biological charateristics, the severe pollution stress and causes to which its water is subjected to, the contents and quality of water and possible remedial measures. An account of algae including pollution sensitive and tolerant species, besides bio-indicators is available. A possible modelling exercise has also been included. A microbiological assay and the bacteria present in the river water is also given. This book, in short, is a synthesis of what the Ganga is at present in respect of its hydrobiology, pollution load, and some aspects of hydrology.
