Book excerpt: Conjunctive water use plan was developed by adopting the optimization and simulation approaches. The study area was divided into fifteen different land units based upon their source of irrigation using the Geographic Information System (GIS). Linear Programming technique was used for maximization of the net profit under the constraints of land, water, food, oil seed, cash crop and fodder requirements. The spatial optimization plan was developed for the study area for the kharif and the rabi seasons separately. In the simulation approach, various alternatives of conjunctive water use scenarios were considered and their impact on groundwater behavior was analysed. Thereafter, a set of those conjunctive water use plans was identified, which could keep the water table within a pre-defined range. Pre-defined range of water table was selected in such a way that the problem of water table depletion or water logging do not occur. The groundwater model MODFLOW was used for analyzing the groundwater behavior. The GIS interface Con2grid was developed to prepare the input file for MODFLOW and display the results.

Available in PDF, EPUB and Kindle. Book excerpt: Groundwater is important and precious freshwater found under the earth's surface. Groundwater is used for human consumption: for drinking, farming and for maintaining surface water system (rivers) especially during low flow periods. For effective groundwater management, quantitative and qualitative status of groundwater is usually assessed using various groundwater models. These models (for example numerical models) are capable of modelling complex and heterogeneous groundwater conditions. However, due to the requirement of extensive and detailed ground water data, these models are not suitable to be applied in all groundwater systems (major and minor aquifers). Therefore, scientific studies in areas of insignificant groundwater resource (minor aquifers) have been underplayed. However, since all groundwater bodies are significantly important, a new groundwater model was developed in this study. GIS functionality was explored and a GIS-based groundwater model was developed using minimal and accessible input data. GIS was used to represent the subsurface geology particularly the aquifer system and to model groundwater flow. The first model, a GIS based geological model was tested by reconstructing the geology map for the Slea catchment, in the United Kingdom and thickness of the Lincolnshire Limestone aquifer was predicted. The advantage of this model is its capability in predicting an aquifer's thickness without referring to point data like those obtained from boreholes. Then, the second model that is based on topographical and groundwater resistance analysis was used to model natural ground water discharge. Although there is discrepancy between estimated and measured spring discharge, the model has confirmed the usefulness of using GIS tool in modelling groundwater exploring minimal input data and basic modelling procedures. The developed models were not a replacement for numerical groundwater models. However, they would be useful to screen ground water status especially in areas that lack ground water data.

Book excerpt: The population on planet Earth will increase from 6 billion to 8.1 billion people in 2030 and will overlap with an augment in water demands to convene human needs, according to FAO forecasts. Fresh water has come to an end to be an unlimited resource to become a relatively limited and scarce one. To meet future demands for food with an increasingly scarcity of water supply, it is a must to manage our water resources better. When water supplies are abundant & environmental pollution & degradation is no issue, water managers can afford to be lax in its management with population growth & the effects of cyclic droughts on irrigated agriculture have put pressure on the available water resources. In managing groundwater resources, Geographical Information System (GIS) are tools capable of storing and managing spatial hydrogeological data by spatial referencing in digital formats. The correlation of all data with location is the key feature of GIS, which provides the ability to analyze and model hydrologic processes and produce results in maps and in digital formats. Thus, GIS can be considered a support system in decision making and an ideal tool for monitoring certain hydrogeological processes with socio-economic impacts. GIS and Geocomputation for Water Resource Science and Engineering not only covers the fundamentals of geographic information systems but also exhibits how GIS and mathematical models can be included to develop spatial decision support systems to support water resources planning, management and engineering. Current GIS applications are presented including surface hydrologic and groundwater modeling, water supply and sewer system modeling, stormwater and nonpoint source pollution modeling for urban and agricultural areas, and other related applications. Future research and development needs in this field are presented. The application of GIS in water resources is constantly on the rise. In order to stress the importance of GIS in water resources management, applications related to this area are addressed and evaluated for efficient future research and development.

Book excerpt: The last few years have witnessed an enormous interest in application of GIS in hydrology and water resources. This is partly evidenced by organization of sev eral national and international symposia or conferences under the sponsorship of various professional organizations. This increased interest is, in a large measure, in response to growing public sensitivity to environmental quality and management. The GIS technology has the ability to capture, store, manipulate, analyze, and visualize the diverse sets of geo-referenced data. On the other hand, hydrology is inherently spatial and distributed hydrologic models have large data requirements. The integration of hydrology and GIS is therefore quite natural. The integration involves three major components: (1) spatial data construction, (2) integration of spatial model layers, and (3) GIS and model interface. GIS can assist in design, calibration, modification and comparison of models. This integration is spreading worldwide and is expected to accelerate in the foreseeable future. Substantial op portunities exist in integration of GIS and hydrology. We believe there are enough challenges in use of GIS for conceptualizing and modeling complex hydrologic processes and for globalization of hydrology. The motivation for this book grew out of the desire to provide under one cover a range of applications of GIS tech nology in hydrology. It is hoped that the book will stimulate others to write more comprehensive texts on this subject of growing importance.

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: This book offers essential information on geospatial technologies for water resource management and highlights the latest GIS and geostatistics techniques as they relate to groundwater. Groundwater is inarguably India's single most important natural resource. It is the foundation of millions of Indian farmers' livelihood security and the primary source of drinking water for a vast majority of Indians in rural and urban areas. The prospects of continued high rates of growth in the Indian economy will, to a great extent, depend on how judiciously we can manage groundwater in the years to come. Over the past three decades, India has emerged as by far the single largest consumer of groundwater in the world. Though groundwater has made the country self-sufficient in terms of food, we face a crisis of dwindling water tables and declining water quality. Deep drilling by tube wells, which was once part of the solution to water shortages, is now in danger of becoming part of the problem. Consequently, we urgently need to focus our efforts on the sustainable and equitable management of groundwater. Addressing that need, this book presents novel advances in and applications of RS–GIS and geostatistical techniques to the research community in a precise and straightforward manner.

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.
