Download or read book Evaluating the Impact of Groundwater Pumping on Meadow Hydrology and Streamflow in the Yosemite Valley written by Nicholas Jordan Newcomb and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater pumping in Yosemite Valley provides up to 200 million gallons of water annually to serve the operational needs of the Park. Until recently, no substantial effort had been made to characterize the groundwater basin in Yosemite or quantify the effects of groundwater abstraction on the valley hydrology near the pumping wells. Field monitoring and a numerical model of groundwater and surface water interaction were used to evaluate the impact of groundwater withdrawals on streamflow in the Merced River and Yosemite Creek and the water table levels in meadows located near the supply wells. The model was constructed using MODFLOW-USG and utilizes the Streamflow Routing Package to represent interaction between the water table and flow in major creeks and rivers. Model calibration, sensitivity analysis, and uncertainty analysis was conducted using UCODE based on shallow groundwater levels measured in 12 piezometers from spring 2012 until fall 2013. Though field and monitoring and model results show that short-term pumping effects are likely dampened by a confining layer separating the pumped aquifer from the water table, modeled pumping impacts compounded throughout the summer and fall results in simulated stream depletion of 6.67% in the Merced River and over 90% in Yosemite Creek. Simulated water table differences in meadows exceed 10 cm over the majority of mapped meadows and reach a maximum of over 50 cm in isolated areas.

Download or read book Riverine Ecosystem Management written by Stefan Schmutz and published by Springer. This book was released on 2018-05-08 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.
Download or read book Climate Change Effects on Groundwater Resources written by Holger Treidel and published by CRC Press. This book was released on 2011-12-02 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is expected to modify the hydrological cycle and affect freshwater resources. Groundwater is a critical source of fresh drinking water for almost half of the world’s population and it also supplies irrigated agriculture. Groundwater is also important in sustaining streams, lakes, wetlands, and associated ecosystems. But despite this, knowledge about the impact of climate change on groundwater quantity and quality is limited. Direct impacts of climate change on natural processes (groundwater recharge, discharge, storage, saltwater intrusion, biogeochemical reactions, chemical fate and transport) may be exacerbated by human activities (indirect impacts). Increased groundwater abstraction, for example, may be needed in areas with unsustainable or contaminated surface water resources caused by droughts and floods. Climate change effects on groundwater resources are, therefore, closely linked to other global change drivers, including population growth, urbanization and land-use change, coupled with other socio-economic and political trends. Groundwater response to global changes is a complex function that depends on climate change and variability, topography, aquifer characteristics, vegetation dynamics, and human activities. This volume contains case studies from diverse aquifer systems, scientific methods, and climatic settings that have been conducted globally under the framework of the UNESCO-IHP project Groundwater Resources Assessment under the Pressures of Humanity and Climate Change (GRAPHIC). This book presents a current and global synthesis of scientific findings and policy recommendations for scientists, water managers and policy makers towards adaptive management of groundwater sustainability under future climate change and variability.

Download or read book Quantitative Assessment of Groundwater and Surface Water Interactions in the Hailiutu River Basin Erdos Plateau China written by Zhi Yang and published by CRC Press. This book was released on 2018-04-17 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study presents a multi-disciplinary approach for investigating the interactions between groundwater and surface water in the semi-arid Hailiutu catchment in the Erdos Plateau, Northwest China. The study consists of statistical detection of river flow regime shifts at the basin level; multiple in-situ measurements for quantifying groundwater discharges using hydraulic, hydrochemical and temperature methods at a local scale; analysis and simulation of impacts of different land use scenarios on groundwater and surface water interactions at the sub-catchment scale; and the quantification of temporal and spatial groundwater and surface water interactions with hydrochemical tracers and modelling methods at the basin scale. The study found that the river flow consists of mainly groundwater discharges at all scales. The river flow regime has been intensively altered by human activities, such as the construction of reservoirs, water diversion, groundwater exploitation, and reforestation. Water use by plants and crops consumes majority of the precipitation. Groundwater sustains vegetation growth and feeds river discharges. The water resources and ecosystem management priority should reduce evaporative water uses by promoting dry resistant plant species for vegetating sand dunes and lower irrigation demand crops for socio-economic development. Furthermore, the Hailiutu River catchment must manage the groundwater recharge for water resource conservation and the maintenance of healthy ecosystems.

Available in PDF, EPUB and Kindle. Book excerpt: The Cretaceous Chalk aquifers of Northern Europe underlie and support many sensitive ecosystems whilst at the same time being an important source of drinking water. Understanding, managing and protecting this valuable asset has always been a challenge and this volume brings together 25 papers representing current knowledge of the Chalk across a variety of thematic sections. The contributions look at aquifer properties, geology and karst; groundwater monitoring in the Chalk; groundwater management; groundwater-fed wetlands; engineering in the Chalk; heat and solute transport; diffuse pollution; and point source pollution. Geographically, the book includes studies undertaken in England, France, Belgium and Denmark. As well as academic papers, many of the chapters are practitioner focused and the editors hope that anyone working in Chalk groundwaters in Northern Europe, whether in academic, consultancy, water company or regulatory roles, will find this book an invaluable resource.
Download or read book Groundwater Resources Modelling written by M. G. Shepley and published by Geological Society of London. This book was released on 2012 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: The UK is a country with over 150 years of widespread exploitation of its principal aquifers for public water supply. Increasing demands, greater awareness of environmental pressures and more exacting legislation has heightened the need for quantitative models to predict the impacts of groundwater use. In the UK this has culminated in a unique national, regulator-led programme for England and Wales to develop conceptual and numerical models of the principal bedrock aquifers. The outcomes of this programme will be of interest to the international hydrogeological community, particularly as international legislation such as the European Water Framework Directive requires management of water issues across administrative boundaries with a varied cast of stakeholders. The collection of papers provides a contrast between practitioner- and research-based approaches to assess and predict the anthropogenic impacts and environmental pressures.
