Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to document for the first time the dimensions and requirements of effective integrated groundwater management (IGM). Groundwater management is a formidable challenge, one that remains one of humanity’s foremost priorities. It has become a largely non-renewable resource that is overexploited in many parts of the world. In the 21st century, the issue moves from how to simply obtain the water we need to how we manage it sustainably for future generations, future economies, and future ecosystems. The focus then becomes one of understanding the drivers and current state of the groundwater resource, and restoring equilibrium to at-risk aquifers. Many interrelated dimensions, however, come to bear when trying to manage groundwater effectively. An integrated approach to groundwater necessarily involves many factors beyond the aquifer itself, such as surface water, water use, water quality, and ecohydrology. Moreover, the science by itself can only define the fundamental bounds of what is possible; effective IGM must also engage the wider community of stakeholders to develop and support policy and other socioeconomic tools needed to realize effective IGM. In order to demonstrate IGM, this book covers theory and principles, embracing: 1) an overview of the dimensions and requirements of groundwater management from an international perspective; 2) the scale of groundwater issues internationally and its links with other sectors, principally energy and climate change; 3) groundwater governance with regard to principles, instruments and institutions available for IGM; 4) biophysical constraints and the capacity and role of hydroecological and hydrogeological science including water quality concerns; and 5) necessary tools including models, data infrastructures, decision support systems and the management of uncertainty. Examples of effective, and failed, IGM are given. Throughout, the importance of the socioeconomic context that connects all effective IGM is emphasized. Taken as a whole, this work relates the many facets of effective IGM, from the catchment to global perspective.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is an analytical summary and a critical synthesis of research at the International Water Management Institute over the past decade under its evolving research paradigm known popularly as 'more crop per drop'. The research synthesized here covers the full range of issues falling in the larger canvas of water-food-health-environment interface. Besides its immediate role in sharing knowledge with the research, donor, and policy communities, this volume also has a larger purpose of promoting a new way of looking at the water issues within the broader development context of food, livelihood, health and environmental challenges. More crop per drop: Revisiting a research paradigm contrasts the acquired wisdom and fresh thinking on some of the most challenging water issues of our times. It describes new tools, approaches, and methodologies and also illustrates them with practical application both from a global perspective and within the local and regional contexts of Asia and Africa. Since this volume brings together all major research works of IWMI, including an almost exhaustive list of citations, in one single set of pages, it is very valuable not only as a reference material for researchers and students but also as a policy tool for decision-makers and development agencies.

Available in PDF, EPUB and Kindle. Book excerpt: Surface water and groundwater systems consist of interconnected reservoirs, rivers, and confined and unconfined aquifers. The integrated management of such resources faces several challenges: High dimensionality refers to the requirement of the large number of variables that need to be considered in the description of surface water and groundwater systems. As the number of these variables increases, the computational requirements quickly saturate the capabilities of the existing management methods. Uncertainty relates to the imprecise nature of many system inputs and parameters, including reservoir and tributary inflows, precipitation, evaporation, aquifer parameters (e.g., hydraulic conductivity and storage coefficient), and various boundary and initial conditions. Uncertainty complicates very significantly the development and application of efficient management models. Nonlinearity is intrinsic to some physical processes and also enters through various facility and operational constraints on reservoir storages, releases, and aquifer drawdown and pumping. Nonlinearities compound the previous difficulties. Multiple objectives pertain to the process of optimizing the use of the integrated surface and groundwater resources to meet various water demands, generate sufficient energy, maintain adequate instream flows, and protect the environment and the ecosystems. Multi-objective decision models and processes continue to challenge professional practice. This research draws on several disciplines including groundwater flow modeling, hydrology and water resources systems, uncertainty analysis, estimation theory, stochastic optimization of dynamical systems, and policy assessment. A summary of the research contributions made in this work follows: 1. High dimensionality issues related to groundwater aquifers system have been mitigated by the use of transfer functions and their representation by state space approximations. 2. Aquifer response under uncertainty of inputs and aquifer parameters is addressed by a new statistical procedure that is applicable to regions of relatively few measurements and incorporates management reliability considerations. 3. The conjunctive management problem is formulated in a generally applicable way, taking into consideration all relevant uncertainties and system objectives. This problem is solved via an efficient stochastic optimization method that overcomes dimensionality limitations. 4. The methods developed in this Thesis are applied to the Jordanian water resources system, demonstrating their value for operational planning and management.

Available in PDF, EPUB and Kindle. Book excerpt: Modern water management aims for sustainability of water use in evolving socioeconomic and environmental scenarios, nevertheless under great defies. In Mediterranean environments such as Chile and California, climate change, droughts, floods, and increasing water demand are challenging our sustainability on water use. As spring arrives early and highland precipitation is frequently rain-on-snow, the snowpack melts sooner, more water runoff in rivers, reservoirs quickly reach capacity, and water is released for flood control. This uncaptured water becomes available across lowland streams and floodplains, away from upgradient areas where recharge normally occurs, and is eventually lost downstream, unless we can store it underground. Moreover, groundwater is not managed very effectively, causing overdrafts and subsidence. If changes in groundwater storage, pumping, and recharge could be tracked in real time, feedback could be provided to water users to minimize undesirable effects. However, groundwater accounting is difficult, done by complex models, and costly in terms of data, money and time. Thus, this research aims to address (1) how the increased early streamflows can be managed in floodplains to maximize recharge in downgradient areas compensating for the loss of surface water storage? and (2) how can dynamics in groundwater be tracked in real time to improve management and transparency? To conduct this work, an existing IWFM (Integrated Water Flow Model) for Yolo County, California, was updated, calibrated, and used as study case. Results presented a promising conjunctive use framework in the Yolo Bypass, a lowland floodplain environment, by recharging Sacramento River excess water, along with a regional pumping scheme to facilitate recharge. Also, hydrologic proxy models are presented to estimate instantly change in storage, pumping, and recharge, with minimum calculations and data. For similar settings, these results can serve water users and managers to enhance water supply and accounting, in order to make well informed decisions for sustainable water use.

Download or read book Modeling Study of Groundwater and Surface Water Interaction Using High Resolution Integrated Model written by Yunjie Liu and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The groundwater and surface water comprise a single source of water resources. Efficient and sustainable water resource management requires using groundwater and surface water conjunctively. Worldwide, many water shortage problems come from the fact that neither the timing nor the location of precipitation coincide with water demands. Climate change makes this problem even worse. For California particularly, the warming trend is shifting more precipitation to fall as rain rather than snow during winter season, thereby reducing snow pack in Sierra Nevada Mountains. In addition, snowmelt is occurring earlier in spring due to warmer temperatures, therefore reducing the availability of snowmelt water that contributes to stream flow and surface reservoirs during dry summer season. Climate projections also suggest that winter floods will become more frequent, as will hotter and drier summers. The imbalance in time of water distribution within a year (wet, dry season), and between years (wet, dry year), as well as extreme climate events (for example, 1997 California flood, 2012-2014 California mega drought), create great challenges for water resource management. It is especially true when climate change effect is expected to continue. This study evaluates winter floodplain inundation as a strategy of capturing and storing excess winter flood water beneath Central Valley floor to restore groundwater for local subsurface reservoir development. The parallel, variably saturated flow modeling code, ParFlow, is chosen to model the spatial and temporal patterns of surface water and groundwater interaction in heterogeneous subsurface under floodplain inundation at lower Cosumnes River floodplain. Particularly, the mechanics of groundwater and surface interaction in heterogeneous subsurface is investigated. Capturing and storing excess winter flood water for the development of local subsurface groundwater reservoir and its impact on water resource management is discussed. Results of this study show that groundwater and surface water interaction under floodplain inundation is controlled by the heterogeneity of subsurface, primarily the connectivity of heterogeneity, as well as flood water inundating dynamics. A local subsurface reservoir can be augmented through floodplain inundation practice. However, its role of mitigating climate change impact on water resource management on a long time frame needs further investigation.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a hard copy of the editorial and all the papers in a Special Issue of the peer-reviewed open access journal ‘Water’ on the theme ‘Managed Aquifer Recharge for Water Resilience’. Managed aquifer recharge (MAR) is the purposeful recharge of water to aquifers for subsequent recovery or environmental benefit. MAR is increasingly used to make water supplies resilient to drought, climate change and deteriorating water quality, and to protect ecosystems from declining groundwater levels. Global MAR has grown exponentially to 10 cu.km/year and will increase ten-fold within a few decades. Well informed hydrogeologists, engineers and water quality scientists are needed to ensure that this investment is effective in meeting increasingly pressing needs. This compilation contains lessons from many examples of existing projects, including several national and continental summaries. It also addresses the elements essential for identifying and advancing projects such as mapping aquifer suitability and opportunities, policy matters, operational issues, and some innovations in MAR methods and monitoring. This collection exemplifies the state of progress in the science and practice of MAR and is intended to be useful, at least to water managers, water utilities, agricultural water users and urban planners, to facilitate water resilience through new MAR projects.
