This book was released on 2014 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater contributes an essential water supply to several communities and ecosystems in the Truckee River Basin. Water resource investigations were conducted through numerical modeling and comparisons to previous work to assess groundwater recharge in the Martis Valley watershed, which is an essential component to the Truckee River hydrographic region. A baseflow analysis was performed to relate annual baseflow to streamflow and precipitation. Results show that changes in groundwater fluctuations are driven by changes in precipitation, and baseflow response is affected by previous precipitation trends. It was estimated that baseflow is roughly one-sixth of mean annual precipitation. A novel method for constructing a hydrogeologic framework model was developed and applied to an integrated surface water-groundwater hydrologic model, GSFLOW, from which groundwater recharge locations and magnitudes were extracted. Model results supplemented previous work and provided enhanced conceptualizations of surface and groundwater interactions, as well as spatial and temporal recharge trends. Results show that the most significant recharge zones are low to mid-elevation stream channel and alluvial areas. During peak snowmelt periods, upper elevation alluvial areas also contribute significant recharge. The findings herein promote a more detailed understanding of groundwater recharge characteristics in high elevation, snow dependent, alpine catchments.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater and surface water resources are increasingly being stressed due to changes in population, land-use, management practices, and climate. Better understanding of system behavior and the complex feedbacks inherent between groundwater, the landscape, and surface water is necessary to predict and mitigate detrimental environmental impacts that may arise from these additional stresses. Integrated hydrologic models are capable of simulating these complex feedbacks, however their complexity and computational expense has resulted in little exploration of these models beyond a necessary calibration. This research presents the development, evaluation, calibration, and application of an integrated hydrologic model developed for the Scott Valley that simulates the connections between land use, groundwater, and surface water in an irrigated agricultural basin. The first chapter focuses on model development, sensitivity analysis and calibration. Results indicate that a weakly coupled, computationally efficient model can be successfully employed in lieu of an iteratively or fully coupled integrated model to simulate highly dynamic groundwater-surface-water interactions in an agricultural watershed, and. Furthermore, a calibration design with multiple sensitivity analyses and calibrations of integrated hydrologic models, each using one of several widely varying sets of initial values, provides a frugal approach to identify parameters across the global parameter space. The second chapter uses the model to explore three different methods of varying computational expense for evaluating prediction uncertainty of three conjunctive use management scenarios designed to increase late-summer streamflow. Uncertainty prediction ranges from the three methods shows that the high degree of nonlinearity in integrated hydrologic models makes them unsuited for computationally frugal linear uncertainty analysis methods. Spatial and temporal depletion/accretion effects from pumping/recharge in the valley are evaluated in the third chapter. Allowing stream sections to go dry during the simulation produces depletion/accretion rates once the stream reconnects that can temporarily exceed the pumping/recharge rate imposed. Modification of the current conceptual model of streamflow depletion is proposed based on these results.

Book Synopsis Climate Change and Groundwater by : Walter Dragoni
Download or read book Climate Change and Groundwater written by Walter Dragoni and published by Geological Society of London. This book was released on 2008 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a general consensus that for the next few decades at least, the Earth will continue its warming. This will inevitably bring about serious environmental problems. For human society, the most severe will be those related to alterations of the hydrological cycle, which is already heavily influenced by human activities. Climate change will directly affect groundwater recharge, groundwater quality and the freshwater-seawater interface. The variations of groundwater storage inevitably entail a variety of geomorphological and engineering effects. In the areas where water resources are likely to diminish, groundwater will be one of the main solutions to prevent drought. In spite of its paramount importance, the issue of 'Climate Change and Groundwater' has been neglected. This volume presents some of the current understanding of the topic.

This book was released on 2021-11-10 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book discusses one of the major challenges in agriculture which is delivery of cultivate produce to the end consumers with best possible price and quality. Currently all over the world, it is found that around 50% of the farm produce never reaches the end consumer due to wastage and suboptimal prices. The authors present solutions to reduce the transport cost, predictability of prices on the past data analytics and the current market conditions, and number of middle hops and agents between the farmer and the end consumer using IoT-based solutions. Again, the demand by consumption of agricultural products could be predicted quantitatively; however, the variation of harvest and production by the change of farm's cultivated area, weather change, disease and insect damage, etc., could be difficult to be predicted, so that the supply and demand of agricultural products has not been controlled properly. To overcome, this edited book designed the IoT-based monitoring system to analyze crop environment and the method to improve the efficiency of decision making by analyzing harvest statistics. The book is also useful for academicians working in the areas of climate changes.

This book was released on 2008 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Technical Paper addresses the issue of freshwater. Sealevel rise is dealt with only insofar as it can lead to impacts on freshwater in coastal areas and beyond. Climate, freshwater, biophysical and socio-economic systems are interconnected in complex ways. Hence, a change in any one of these can induce a change in any other. Freshwater-related issues are critical in determining key regional and sectoral vulnerabilities. Therefore, the relationship between climate change and freshwater resources is of primary concern to human society and also has implications for all living species. -- page vii.

Download or read book FEFLOW written by Hans-Jörg G. Diersch and published by Springer Science & Business Media. This book was released on 2013-11-22 with total page 1018 pages. Available in PDF, EPUB and Kindle. Book excerpt: FEFLOW is an acronym of Finite Element subsurface FLOW simulation system and solves the governing flow, mass and heat transport equations in porous and fractured media by a multidimensional finite element method for complex geometric and parametric situations including variable fluid density, variable saturation, free surface(s), multispecies reaction kinetics, non-isothermal flow and multidiffusive effects. FEFLOW comprises theoretical work, modeling experiences and simulation practice from a period of about 40 years. In this light, the main objective of the present book is to share this achieved level of modeling with all required details of the physical and numerical background with the reader. The book is intended to put advanced theoretical and numerical methods into the hands of modeling practitioners and scientists. It starts with a more general theory for all relevant flow and transport phenomena on the basis of the continuum approach, systematically develops the basic framework for important classes of problems (e.g., multiphase/multispecies non-isothermal flow and transport phenomena, discrete features, aquifer-averaged equations, geothermal processes), introduces finite-element techniques for solving the basic balance equations, in detail discusses advanced numerical algorithms for the resulting nonlinear and linear problems and completes with a number of benchmarks, applications and exercises to illustrate the different types of problems and ways to tackle them successfully (e.g., flow and seepage problems, unsaturated-saturated flow, advective-diffusion transport, saltwater intrusion, geothermal and thermohaline flow).

Download or read book Climate Change, Food Security and Natural Resource Management written by Mohamed Behnassi and published by Springer. This book was released on 2018-11-15 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contributes to the on-going debates on climate change by focusing on the SDGs and exploring linkages between environmental change and food security as well as the relevance and need to consider the management of natural resources, especially water, soil and forest. Compared to relevant existing publications, this book covers case studies that capture the everyday realities of the local people and how they react and adapt to similar situations in different geographical settings. Each case study presented in this book gives a particular message. The strength of this book lies in the fact that it covers the most neglected topics in climate negotiations in spite of the fact that these decide the fate of millions of people around the world, especially the developing countries. By presenting a collection of case studies from Africa, Asia and Europe, this book encourages cross-continental knowledge sharing. The scope of the book ranges from impacts to mitigation and from in-field experiments to policy implementation. It contributes to the existing knowledge on climate-food nexus and connects climate change to sectors it could impact directly. All chapters in this book emphasise local ownership of strategy processes, effective participation from all levels, and high-level commitment. Besides being relevant for the academicians and scholars working in the field of climate change, forest and agriculture, it aims to catch interest of the policy makers and practitioners to understand ground realities for appropriate action. It is also bound to make an impact on the Non-Governmental Organizations around the world and in the three different continents that this book covers, considering the indigenous and local issues highlighted in this book.
