Book excerpt: Changes in Konya's Mediterranean climate and water demand are expected to alter water operations in Konya Closed Basin, and creating a substantial need for an integrated model to explore new scenarios for future adaptations. Located on a high altitude plain of central Turkey, Konya is an important agricultural region for entire country. Konya is a semi-arid region, with hot and dry summers. Precipitation occurs usually in the winter and spring. Limited water supply sources make water management a necessity in the region. This study introduces a new bottom-up modeling approach that takes into account groundwater, surface water, and climate. Surface water and groundwater are modeled with IWFM (Integrated Water Flow Model), a water resources management and planning model that simulates groundwater, surface water, stream-groundwater interaction, and other components of the hydrologic system. Agricultural operations and demand are represented using IDC (IWFM Demand Calculator), the stand-alone executable version of the root zone component of IWFM. This integrated model allows us to evaluate several operations under different climatic conditions and water demand scenarios, and can increase the reliability of management of scarce water supply resources at Konya Closed Basin. The goal of this study is to develop a groundwater/surface water budget which can be used for the future management actions on Konya Closed Basin water resources.

Book excerpt: River basins are complex areas, combining the natural processes of precipitation, evapotranspiration, surface water and groundwater runoff with man-made features such as dams and reservoirs, diversions and irrigation schemes, and industrial and urban water uses. Computer models may be constructed to represent these natural and man-made processes. Such models are used to help understand processes that are difficult to measure (such as evaporation) and to study the effects of changes in land cover, water management or climate on the natural and man-made processes.

Available in PDF, EPUB and Kindle. Book excerpt: The world is facing severe and growing challenges in maintainig water quality and meeting the rapidly growing demand for water resources. In addition, water used for irrigation, the largest use of water in most developing countries, will likely have to be diverted increasingly to meet the needs of urban areas and industry whilst remaining a prime engine of agricultural growth. Finally, environmental and other in-stream water demands become more important as economies develop. The river basin has been acknowledged to be the appropriate unit of analysis to address these chanllenges facing water resources management: and modeling at this scale can provide essential information for policy makers in their decisions on allication of resources. This paper reviews the state of the art of modeling approaches to integrated water resources management at the river basin scale, with particular focus on the potential of coupled economic hydrologic models, and concludes with directions for future modeling exercises.

Book excerpt: Integrated Flow Modeling presents the formulation, development and application of an integrated flow simulator (IFLO). Integrated flow models make it possible to work directly with seismically generated data at any time during the life of the reservoir. An integrated flow model combines a traditional flow model with a petrophysical model. The text discusses properties of porous media within the context of multidisciplinary reservoir modeling, and presents the technical details needed to understand and apply the simulator to realistic problems. Exercises throughout the text direct the reader to software applications using IFLO input data sets and an executable version of IFLO provided with the text. The text-software combination provides the resources needed to convey both theoretical concepts and practical skills to geoscientists and engineers.
Download or read book Hydrological Modeling written by Ramakar Jha and published by Springer Nature. This book was released on 2022-02-05 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book carefully considers hydrological models which are essential for predicting floods, droughts, soil moisture estimation, land use change detection, geomorphology and water structures. The book highlights recent advances in the area of hydrological modelling in the Ganga Basin and other internationally important river basins. The impact of climate change on water resources is a global concern. Water resources in many countries are already stressed, and climate change along with burgeoning population, rising standard of living and increasing demand are adding to the stress. Furthermore, river basins are becoming less resilient to climatic vagaries. Fundamental to addressing these issues is hydrological modelling which is covered in this book. Integrated water resources management is vital to ensure water and food security. Integral to the management is groundwater and solute transport, and this book encompasses tools that will be useful to mitigate the adverse consequences of natural disasters.

This book was released on 2006-01-01 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report develops an integrated economic-hydrologic river basin model and applies it to the Maipo River Basin in central Chile. Policy simulations based on the modeling framework can serve as a guide for water resource managers and policymakers in designing appropriate water policies and establishing reform priorities for water resource allocation. Alternative analyses undertaken for the Maipo basin-a mature water economy with limited resources and competition for water across all water-using sectors-offer new insights into the changing relationships between irrigation system and basin-level water use efficiencies. They also show how these changing relationships affect farm incomes and environmental impacts. Simulations also provide new results on the role that the trading of water use rights can play in maintaining farm production levels, enhancing farmer incomes, and increasing water use efficiencies.

This book was released on 2012-12-06 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in computer technology, in the technology of communication and in mathematical modelling of processes in the hydrological cycle have recently improved our potential to protect ourselves against damage through floods and droughts and to control quantities and qualities in our water systems. This development was demonstrated in a 1983 post-experience course at Wageningen University where an international group of experts reviewed successful modelling techniques and described the design and operation of a number of forecasting and control systems in drainage basins and river reaches of various sizes and under various geographical and climat ological conditions. A special effort was made to bridge the gap between theory and practice; case studies showed that each forecasting system was designed to meet a set of specific requirements and they illustrated that the forecasting system can only be expected to operate reliably if, on the one hand, it is based on sound theoretical concepts and methods and if, on the other hand, it is robust so that, also under adverse conditions, it will continue to collect and process the necessary input data and produce correct and timely signals. We were pleased to meet with encouragement for preserving the course material and making it available to a wider public. This was effected by the team of authorf who elaborated, updated and harmonized the materia in two stages; first into an issue of our university department and finally into the manuscript of this book.

Available in PDF, EPUB and Kindle. Book excerpt: Groundwater constitutes an important component of many water resource systems, supplying water for domestic use, for industry, and for agriculture. Management of a groundwater system, an aquifer, or a system of aquifers, means making such decisions as to the total quantity of water to be withdrawn annually, the location of wells for pumping and for artificial recharge and their rates, and control conditions at aquifer boundaries. Not less important are decisions related to groundwater qUality. In fact, the quantity and quality problems cannot be separated. In many parts of the world, with the increased withdrawal of ground water, often beyond permissible limits, the quality of groundwater has been continuously deteriorating, causing much concern to both suppliers and users. In recent years, in addition to general groundwater quality aspects, public attention has been focused on groundwater contamination by hazardous industrial wastes, by leachate from landfills, by oil spills, and by agricultural activities such as the use of fertilizers, pesticides, and herbicides, and by radioactive waste in repositories located in deep geological formations, to mention some of the most acute contamination sources. In all these cases, management means making decisions to achieve goals without violating specified constraints. In order to enable the planner, or the decision maker, to compare alternative modes of action and to ensure that the constraints are not violated, a tool is needed that will provide information about the response of the system (the aquifer) to various alternatives.

This book was released on 2016 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation consists of three self-contained, yet closely related, papers summarizing the results of a comprehensive study aimed at the development of a decision support system for sustainable water resources management for the Zhangye Basin in northwestern China. The first paper presents a 3D groundwater flow model to represent groundwater dynamics of the basin from 1999 through 2010 using MODFLOW-2005. The regional 3D groundwater model provides reliable information of the flow field and produces detailed water budgets for management purposes. It defines the intensive groundwater-surface water interaction zones, and reveals the increasing flux exchange due to both climate change and human activities. The second paper presents an integrated 3D groundwater-surface water flow model using GSFLOW. The model calibration was done by first running PRMS and MODFLOW-2005 models separately, and then followed by the calibration of the integrated GSFLOW model. The model shows a detailed trend of water storage changes and their relationship with each inflow and outflow item. More importantly, this study demonstrates the applicability of integrated basin-scale models in characterizing the groundwater-surface water(GWSW) interaction, reproducing the flow system, and supporting sustainable water resources management while accounting for the effects of climate change in arid inland river basins. The third paper presents an efficient decision support tool, taking into consideration the relevant complexities and interactions in different water resource components, to inform decision making for water resources management for the Zhangye basin. On the basis of data collection and data mining, incorporated with integrated hydrological conceptual models and numerical models, a Bayesian network (BN) has been developed and calibrated by K-fold cross validation. The trained BN model captures the important hydrological cycle characteristics and uncertainty of related factors to provide the optimal management solutions under consideration. While this study is based on the Zhangye basin, the concepts and approaches developed in this study are of general applicability. The integrated GWSW modeling, coupled with a BN construct, provides an innovative tool to inform decision making in water resources management.

Available in PDF, EPUB and Kindle. Book excerpt: This volume describes the nature, causes, and consequences of the diverse fluid movements that produce energy and mineral resources in sedimentary basins. The contained papers point to new capabilities in basin analysis methods and models. The processes that operate in the resource-producing thermo-chemical-structural reactors we call sedimentary basins are reviewed. Efficient ways to infer the tectonic history of basins are described. Impacts on hydrocarbon maturation and migration of glacial tilting, magmatic intrusion, salt migration, and fracturing are illustrated. The conditions under which subsurface flow will channel with distance traveled are identified. Seismic methods that can image and map subsurface permeability channels are described. The surface maturation, surface charge, and chemical reaction foundations of creep subsidence are set forth. Dynamic aspects of the hydrogen resource in basins are analyzed. There is much that is new that is presented in these papers with the intent of stimulating thinking and enthusiasm for the advances that will be made in future decades.

Download or read book A Decision Framework for Integrated Wetland River Basin Management in a Tropical and Data Scarce Environment written by Mijail Eduardo Arias Hidalgo and published by CRC Press. This book was released on 2013-01-15 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, wetlands were considered separately from river basin systems. However, nowadays it is becoming common practice to follow an integrated approach in wetland-riverine watershed analysis and management. Such approach requires not only adequate representations of all relevant bio-physical parameters, but also of socio-political and economic indicators. Data scarcity, an endemic problem in developing countries, hampers this global process. In this study, both conventional methods and state-of-the-art techniques and data sources are explored. A modelling framework is developed which includes rainfall-runoff processes, river hydrodynamics and water allocation models, seeking a balance between sophistication and simplicity, in view of data availability conditions. The framework was used to evaluate a number of scenarios, including potential effects of climatic variations and of the major hydraulic works that are planned by the national water authority. Several management options were assessed through this tool. In addition, special indicators were developed to remedy the lack of sufficient quantitative information by using a qualitative approach based on expert elicitation and stakeholder involvement. A decision support framework was applied to achieve a final ranking of the various management solutions that are in compliance with the national policies, facilitating the further development of management guidelines for wetlands across the Ecuadorian lowlands. The book will be of interest to water managers, hydro-informaticians/water modellers, people working at river basin authorities and Ministries of the environment.
