Available in PDF, EPUB and Kindle. Book excerpt: The Ganges Basin is a part of the Ganges-Brahmaputra-Meghna (GBM) River Basin and is one of the most populated (600 million) river basins in the world. This study focuses on the Eastern Ganges Basin (EGB) and covers India (Bihar, Jharkhand and West Bengal), Bangladesh and the Nepal Terai. Poverty is acute in the EGB, where household incomes are low, food security is not assured and devastating floods (and also water shortages) occur too often. The EGB is underlain by one of the most prolific aquifers in the world. Yet, farmers struggle to cope with dry spells and droughts because of their inability to access groundwater. Huge untapped groundwater, surplus surface water, and enormous plains and fertile lands highlight the requirement of proper planning for groundwater management and governance to reduce poverty and assure food security. The aim of this report is to assist planners/policymakers in the planning and management of groundwater resources in the EGB. This report mainly discusses about hydrogeology, groundwater potential and challenges, and groundwater quality issues in the EGB. Moreover, it is an attempt to form a base for future work related to groundwater development, management and modeling in this basin.

This book was released on 2021-01-04 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an overview of the hydrometeorological and hydrological studies and assists in tackling challenges posed by climate and land use land cover changes. The Ganga River is one of the major living streams on the planet earth and very important river system in India. This holy river is a lifeline for approximately five hundred million people. In the last few decades, River Ganges has been subjected to tremendous pressures with respect to both water quantity and water quality. This situation, already one of the alarming magnitudes, has been further provoked by hydrometeorological changes resulting in droughts, floods and reduced groundwater levels and river flows in addition to the poor river health. Thus, it is imperative to assess the various complexities and possible solutions for better management of River Ganges. This book is a valuable addition to the literature and contributes to research on River Ganges which will help better planning and management of Ganga river basin. The hydrological and hydrometeorological aspects covered in this book help practitioners, researchers, policymakers and other stakeholders.
Download or read book The Impacts of Water Infrastructure and Climate Change on the Hydrology of the Upper Ganges River Basin written by Luna Bharati and published by IWMI. This book was released on 2011 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study assessed the variability of flows under present and ‘naturalized’ basin conditions in the Upper Ganges Basin (UGB). Furthermore, the PRECIS regional climate model (RCM) was used to generate climate projections for the UGB, with subsequent simulations of future river flows. Results show that the annual average precipitation, actual evapotranspiration (ET) and net water yields of the whole basin were 1,192 mm, 416 mm and 615 mm, respectively. Precipitation, ET and water yields were found to be higher in the forested and mountainous upper areas of the UGB. On an annual average, present-day flows throughout UGB are about 2-8% lower than under naturalized conditions. Dry and wet season flows under climate change (CC) scenario A2 are lower than that under present climate conditions at upstream locations, but higher at downstream locations of UGB. Flows under CC scenario B2 are systematically higher and lower than that under CC scenario A2 during dry and wet seasons, respectively.
Download or read book Neo Thinking on Ganges Brahmaputra Basin Geomorphology written by Balai Chandra Das and published by Springer. This book was released on 2016-01-08 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the latest advances in our understanding of the evolution of the Ganga-Brahmaputra delta, examining the Damodar basin, Bhagirathi-Hooghly basin and Jalangi basin from historical, quantitative and applied geomorphology perspectives. The evolution of the Ganga-Brahmaputra delta is highly complex and remains poorly understood. To address that gap, this edited volume presents 11 research papers: the first seven chapters focus on the pure geomorphology and geohydrology of the delta, while the remaining four examine its applied geomorphological aspects. The book offers a valuable guide for geologists, geographers, hydrologists, landscape ecologists, environmentalists, engineers, planners and policy makers.
Download or read book Reviving the Ganges water machine potential and challenges to meet increasing water demand in the Ganges River Basin written by Amarasinghe, Upali A. and published by IWMI. This book was released on 2016-12-05 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the Ganges River Basin (GRB) has abundant water resources, the seasonal monsoon causes a mismatch in water supply and demand, which creates severe water-related challenges for the people living in the basin, the rapidly growing economy and the environment. Addressing these increasing challenges will depend on how people manage the basin’s groundwater resources, on which the reliance will increase further due to limited prospects for additional surface storage development. This report assesses the potential of the Ganges Water Machine (GWM), a concept proposed 40 years ago, to meet the increasing water demand through groundwater, and mitigate the impacts of floods and droughts. The GWM provides additional subsurface storage (SSS) through the accelerated use of groundwater prior to the onset of the monsoon season, and subsequent recharging of this SSS through monsoon surface runoff. It was identified that there is potential to enhance SSS through managed aquifer recharge during the monsoon season, and to use solar energy for groundwater pumping, which is financially more viable than using diesel as practiced in many areas at present. The report further explores the limitations associated with water quality issues for pumping and recharge in the GRB, and discusses other related challenges, including availability of land for recharge structures and people’s willingness to increase the cropping intensity beyond the present level.

Available in PDF, EPUB and Kindle. Book excerpt: From time immemorial the Bengal Delta had been an important maritime des- nation for traders from all parts of the world. The actual location of the port of call varied from time to time in line with the natural hydrographic changes. From the early decades of the second millennium AD, traders from the European con- nent also joined the traders from the Arab countries, who had been the Forerunners in maritime trading with India. Daring traders and fortune seekers from Denmark, Holland, Belgium and England arrived at different ports of call along the Hooghly river. The river had been, in the meantime, losing its pre-eminence as the main outlet channel of the sacred Ganga into the Bay of Bengal, owing to a shift of ?ow towards east near Rajmahal into the Padma, which had been so long, carried very small part of the large volume of ?ow. On a cloudy afternoon on August 24, 1690 the British seafarer Job Charnock rested his oars at Kolkata and started a new chapter in the life of a sleepy village, bordering the Sunderbans which was ‘a tangled region of estuaries, rivers and water courses, enclosing a vast number of islands of various shapes and sizes. ’ and infested with a large variety of wild animals. In the language of the British Nobel Laureate (1907) Rudyard Kipling (1865–1936). ???? ???? Thus the midday halt of Charnock grew a city.

Download or read book Extent of Arsenic Contamination and Its Impact on the Food Chain and Human Health in the Eastern Ganges Basin written by N. Rajmohan and published by IWMI. This book was released on 2014-01-01 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exposure to arsenic and the use of arsenic-contaminated groundwater in agriculture causes serious health issues. Complete or partial contamination of groundwater is reported worldwide, especially in the Eastern Gangetic Basin (EGB). This study aims to create an overall assessment of arsenic contamination in the EGB based on existing literature, demarcate the extent of the affected area, highlight the impacts on the food chain and human health, and hopes the research will help in the better planning and management of groundwater. Although several studies have evaluated arsenic contamination of groundwater in the EGB, (a) there is no proper long-term monitoring being done in affected areas; (b) there is a debate to identify the exact source and transport processes of arsenic occurrence in this region; (c) there is no comprehensive method to estimate the level of arsenic contamination in soil, water and the food chain; and (d) Arsenic contamination in Bihar and Nepal is not evaluated systematically, especially arsenic accumulation in the food chain and human health issues. Data scarcity and accessibility are the major challenges in this region. Thus, this review recommends systematic monitoring and analysis of arsenic contamination in groundwater, soils and food across the EGB.
