Book Groundwater Surface Water Interactions

Download or read book Groundwater Surface Water Interactions written by Habil. Jörg Lewandowski and published by MDPI. This book was released on 2020-12-10 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen a paradigm shift in our understanding of groundwater–surface water interactions: surface water and aquifers were long considered discrete, separate entities; they are now understood as integral components of a surface–subsurface continuum. This book provides an overview of current research advances and innovative approaches in groundwater–surface water interactions. The 20 research articles and 1 communication cover a wide range of thematic scopes, scales, and experimental and modelling methods across different disciplines (hydrology, aquatic ecology, biogeochemistry, and environmental pollution). The book identifies current knowledge gaps and reveals the challenges in establishing standardized measurement, observation, and assessment approaches. It includes current hot topcis with environmental and societal relevance such as eutrophication, retention of legacy, and emerging pollutants (e.g., pharmaceuticals and microplastics), urban water interfaces, and climate change impacts. The book demonstrates the relevance of processes at groundwater–surface water interfaces for (1) regional water balances and (2) quality and quantity of drinking water resources. As such, this book represents the long-awaited transfer of the above-mentioned paradigm shift in understanding of groundwater–surface water interactions from science to practice.

Book Modeling Surface Water and Groundwater Interactions in Agricultural Areas

Download or read book Modeling Surface Water and Groundwater Interactions in Agricultural Areas written by Gengxin Ou and published by . This book was released on 2015 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation research, three modeling tools have been developed to help quantify the complex processes of integrated surface- and ground-water systems in an area under significant agricultural development of Nebraska. To evaluate irrigation effect on stream depletion for the Lower Platte River (LPR) basin, a regional three-dimensional, transient groundwater-flow model is established with MODFLOW. A simplified and more efficient solution has been developed to estimate the stream depletion rate by re-using the flow coefficients of the baseline run. The flow equation is linearized because the head coefficients become constant between solver iterations. The tool has been successfully applied to the LPR model. The results show that the stream depletion analysis tool can reduce the numerical errors produced in the conventional method and improve the computational efficiency. The second modeling tool is a cross-section based streamflow routing (CSR) package for MODFLOW to simulate the streamflow and the interaction between streams and aquifers for the stream with a width larger than the MODFLOW grid size. In the CSR package, streams are divided into stream segments which are formed by two consecutive cross-sections. A rapid algorithm is used to compute the submerged area of the MODFLOW grid. Stream-aquifer seepage is treated as lateral flow in the streamflow routing computation with the Muskingum-Cunge method or mass conservation method. A hypothetical problem was established to test the capabilities of the CSR package with steady- and transient-state models. The third part of this dissertation aims to quantify the impacts of natural processes and human activities on ground-water dynamics in highly agricultural areas by developing an integrated surface-ground water model (ISGWM). In ISGWM, SWAT and MODFLOW are linked by a soil water module (SWM), which is developed based on a non-iterative solution of the 1D Richards equation. SWM explicitly represents infiltration, soil evaporation, unsaturated water flow, root water update, and lateral drainage. Taking advantage of the simulation capacities of these SWAT, MODFLOW and SWM, ISGWM can simulate the physical hydrologic processes in three domains and their interactions. The model has been successfully applied to the Johnson Creek watershed, which is located within the Lower Platte Basin.

Book Investigation of Groundwater Surface Water Interactions Application to Leech Lake Aquifer

Download or read book Investigation of Groundwater Surface Water Interactions Application to Leech Lake Aquifer written by Arefin Haque and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Looking into the resources essential for socio-economic development, water resources are inevitable. Food, feed, and shelter requirements are growing rapidly with the increase in the population of our world and on the other hand water resources are becoming scarcer to fulfill these demands. Therefore, it is highly required to manage these resources in the best possible way and to contribute towards their sustainability.Water can play a key facilitating role to ensure sustainable development if both groundwater and surface water can be managed efficiently and equitably through the application of fully integrated systems. This study represents an integrated methodology by using the physically-based surface- subsurface flow model (HydroGeoSphere) for the estimation of the effects of climate change and groundwater withdrawal on the corresponding groundwater aquifer systems. This study is conducted for one of the aquifers (Leech lake aquifer) of the City of Yorkton which is recognized as one of the largest urban centers in Saskatchewan depending entirely on groundwater. Finite element based fully coupled model, HydroGeoSphere (HGS) has been selected because it acts as a comprehensive and integrated framework accounting for both surface and subsurface flows, solute and energy transport. In addition, simpler either loosely or externally coupled models do not seem to offer the same level of flexibility in assigning properties and boundary conditions. Digital Elevation Model (DEM) for the subsurface layers has been constructed in Surfer 16 by means of the cross-sectional log data obtained from the City of Yorkton whereas the DEM for the surface layer has been extracted from the Geospatial Canada website. This defines the bottom and the top layers, respectively, and in between lies the computational domain. Validation and calibration exercises were conducted to build confidence in the modeling approach and to estimate some parameters. The validation exercises were conducted against groundwater head observations of four monitoring wells in the period from 2002 to 2015. Simulation results were showing reasonably accurate matches with the observations and this accuracy has been certified by some of the frequently used statistical error analysis tools. From both observations and simulations, it has been found that the drawdowns in the existing observation wells generally lie within the range of 1 to 3 m whereas it could go a maximum of 5 m in the location of production wells. Different recharge and withdrawal scenarios have been evaluated for providing a sustainable management plan, starting from 1 year (short-term) to 100 years (long-term). In addition, an evacuation scenario has been taken into consideration under adverse climate change conditions (assuming neither any rainfall nor snowmelt). This specific case is being simulated to know the withdrawal rate of pumping wells which could evacuate the whole reservoir. Determination and interpretation of exchange flow rates at the interface between surface water bodies and its associated subsurface aquifer layers is another significant outcome of this research. That is to say, this fully coupled model advances the illustration of mutually dependent processes like recharge, which is vital in the context of climate change. This modeling case study has been executed to support the viability of this integrated approach in replicating the existing condition which could be further used as a prediction model in the light of quick and unpredictable changes.

Book Unsaturated Flow in Hydrologic Modeling

Download or read book Unsaturated Flow in Hydrologic Modeling written by H.J. Morel-Seytoux and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume certainly is a Conference Proceedings, the Proceedings of the NATO Advanced Research Workshop (ARW) on "Unsaturated Flow in Hydrologic Modeling" held at "Les Villages du Soleil" near ArIes, France from June 13 to 17, 1988. Let me therefore acknowledge properly, at the very beginning, the gratitude of all the participants to the NATO Science Committee for its generous support and worthwhile goal of bringing together scientists of many countries to communicate and share their experiences. Particular thanks are extended to the director of the program, Dr. Luis Vega da Cunha for his interest and understanding. On the other hand this volume is also, and probably more so, a Textbook that fills a gap in the field of unsaturated flow. Many treatises on the subject present the theory in its different aspects. Hardly any explain in details how the different pieces can be put together to address realistic problems at the basin scale. The various invited contributions to the ARW were structured in a subject progression much as chapters are organized in a book. The intent of the ARW was to assess the current state of knowledge in "Unsaturated Flow" and its use in "Hydrologic Modeling Practice". In a sense the interest in fundamentals of unsaturated flow in this ARW was not just for the sake of knowledge but also and primarily for the sake of action. Can such fundamental knowledge be utilized for better management of the water resource? was the basic question.
