Download or read book River Sand Mining Modelling and Sustainable Practice written by Raj Kumar Bhattacharya and published by Springer Nature. This book was released on 2021-07-31 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: Worldwide demand for sand and gravel is increasing daily, as the need for these materials continues to rise, for example in the construction sector, in land filling and for transportation sector based infrastructural projects. This results in over-extraction of sand from channel beds, and hampers the natural renewal of sediment, geological setup and morphological processes of the riverine system. In India, illegal sand mining (of alluvial channels) and gravel mining (of perennial channels) are two anthropogenic issues that negatively affect the sustainable drainage system. Along the Kangsabati River in India, the consequences of sand mining are very serious. The construction of Mukutmonipur Dam (1958) on the river causes huge sediment deposition along the middle and downstream areas, these same areas are also intensely mined for sand (instream and on the flood plain). Geospatial models are applied in order to better understand the state and the resilience of stream hydraulics, morphological and river ecosystem variables during pre-mining and post-mining stages, using micro-level datasets of the Kangsabati River. The book also includes practicable measures to minimize the environmental consequences of instream mining in respect to optimum sand mining. It discusses the threshold limits of each variable in stream hydraulics, morphological and river ecological regime, and also discusses the most affected variables. Consequently, all outputs will be very useful for students, researchers, academicians, decision makers and practitioners and will facilitate applying these techniques to create models for other river basins.
Download or read book Sand Mining written by D. Padmalal and published by Springer. This book was released on 2014-06-12 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses most of the environmental impacts of sand mining from small rivers The problems and solutions addressed in this book are applicable to all rivers that drain through densely populated tropical coasts undergoing rapid economic growth. Many rivers in the world are drastically being altered to levels often beyond their natural resilience capability. Among the different types of human interventions, mining of sand and gravel is the most disastrous one, as the activity threatens the very existence of river ecosystem. A better understanding of sand budget is necessary if the problems of river and coastal environments are to be solved.

Download or read book Coastal Ecosystems of the Tropics Adaptive Management written by Velmurugan Ayyam and published by Springer Nature. This book was released on 2019-10-11 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: The coastal areas of the tropics are rich in biodiversity, natural resources and place of intensive developmental activities as it provides livelihood to millions of people. At the same time evidences suggest that several unique coastal ecosystems viz., mangroves, wetlands, salt marshes, corals, estuaries, sand dunes and agro-ecosystem are vulnerable to natural disasters and events associated with global climate change. In recent times degradation of land, water and genetic erosion besides threat to native flora and fauna have been increasing due to unsustainable developmental activities. Therefore, a paradigm shift in deriving livelihood through conventional methods, developmental strategies, conservation practices are required for balanced and sustainable growth of the coastal areas. This publication strives to cover the status of different natural resources of the coastal region, various aspects of degradation process, production need and restorative methods besides new technological options and its socio-economic implications with case examples. Special focus is given to bring out the scope and potential of mangrove based farming, integrated and organic farming and its value addition besides the role of coastal vegetations as bioshield in protecting these regions from sea erosion, cyclones and tsunami. As the tropical coastal areas are vulnerable to climate change events, this book also covers the recent weather pattern, impacts of climate change and climate resilient technologies besides intuitional linkages and policy framework aimed at balancing development and environmental concerns.
Download or read book Vanishing Sands written by Orrin H. Pilkey and published by Duke University Press. This book was released on 2022-09-12 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a time of accelerating sea level rise and increasingly intensifying storms, the world’s sandy beaches and dunes have never been more crucial to protecting coastal environments. Yet, in order to meet the demands of large-scale construction projects, sand mining is stripping beaches and dunes, destroying environments, and exploiting labor in the process. The authors of Vanishing Sands track the devastating impact of legal and illegal sand mining over the past twenty years, ranging from Africa, Asia, and the Caribbean to South America and the eastern United States. They show how sand mining has reached crisis levels: beach, dune, and river ecosystems are in danger of being lost forever, while organized crime groups use deadly force to protect their illegal mining operations. Calling for immediate and widespread resistance to sand mining, the authors demonstrate that its cessation is paramount for saving not only beaches, dunes, and associated environments but also lives and tourism economies everywhere.

Available in PDF, EPUB and Kindle. Book excerpt: Sand and gravels are the unrecognised foundational material of our economies. They are mined the world over, with aggregates accounting for the largest volume of solid material extracted globally (Peduzzi, 2014; Beiser, 2018). At the same time, these materials cannot be produced from our terrestrial, riverine and marine environments in quantities needed to meet demand from a world of 10 billion people without effective policy, planning, regulation and management. Such actions remain largely unaddressed by decision makers in public or private sectors. It is time to challenge the paradigm of infinite sand resources through constructive dialogue and solution-finding. This report aims to be the starting point from which a productive global conversation on sand extraction can begin. This synthesis was produced following a United Nations Environment Programme expert roundtable event held on 11 October 2018 in Geneva, Switzerland. The discussions emphasised potential solutions for mitigating mineral sands and aggregates extraction impacts and generating adequate support for responsible consumption pathways. Expert views were collated and complemented with additional research and consultation to distil key messages on an agenda for tackling this issue in 2019 and beyond.

Book excerpt: A finalist for the PEN/E. O. Wilson Literary Science Writing Award The gripping story of the most important overlooked commodity in the world--sand--and the crucial role it plays in our lives. After water and air, sand is the natural resource that we consume more than any other--even more than oil. Every concrete building and paved road on Earth, every computer screen and silicon chip, is made from sand. From Egypt's pyramids to the Hubble telescope, from the world's tallest skyscraper to the sidewalk below it, from Chartres' stained-glass windows to your iPhone, sand shelters us, empowers us, engages us, and inspires us. It's the ingredient that makes possible our cities, our science, our lives--and our future. And, incredibly, we're running out of it. The World in a Grain is the compelling true story of the hugely important and diminishing natural resource that grows more essential every day, and of the people who mine it, sell it, build with it--and sometimes, even kill for it. It's also a provocative examination of the serious human and environmental costs incurred by our dependence on sand, which has received little public attention. Not all sand is created equal: Some of the easiest sand to get to is the least useful. Award-winning journalist Vince Beiser delves deep into this world, taking readers on a journey across the globe, from the United States to remote corners of India, China, and Dubai to explain why sand is so crucial to modern life. Along the way, readers encounter world-changing innovators, island-building entrepreneurs, desert fighters, and murderous sand pirates. The result is an entertaining and eye-opening work, one that is both unexpected and involving, rippling with fascinating detail and filled with surprising characters.

Download or read book Reservoir Sedimentation written by G.W. Annandale and published by Elsevier. This book was released on 1987-01-01 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Sand Control in Well Construction and Operation written by Davorin Matanovic and published by Springer Science & Business Media. This book was released on 2012-02-21 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Produced sand causes a lot of problems. From that reasons sand production must be monitored and kept within acceptable limits. Sand control problems in wells result from improper completion techniques or changes in reservoir properties. The idea is to provide support to the formation to prevent movement under stresses resulting from fluid flow from reservoir to well bore. That means that sand control often result with reduced well production. Control of sand production is achieved by: reducing drag forces (the cheapest and most effective method), mechanical sand bridging (screens, gravel packs) and increasing of formation strength (chemical consolidation). For open hole completions or with un-cemented slotted liners/screens sand failure will occur and must be predicted. Main problem is plugging. To combat well failures due to plugging and sand breakthrough Water-Packing or Shunt-Packing are used.
