Geospatial Tools for Urban Water Resources

 


Preface of the Book

Advances in the field of geospatial technologies have resulted in the growth in the application of such methods and techniques to a wider range of challenges and issues associated with urban water resources. The use of remote sensing, geographic information science (GIS), spatial analysis, global positioning systems (GPS),


digital mapping, online electronic data resources, and processing techniques are now common tools in addressing urban water quality, storm water, flooding, water supply issues, and overall management of water resources and watersheds in urban communities and urbanizing landscapes. In this volume, the authors address many of the complex concerns and impacts associated with human and natural changes


facing urban water resources through their use of a variety of geospatial techniques and tools. The aim of the volume is to present the reader a mix of examples of the evolving use of geospatial methods and applications now utilized in many urban areas to assist decision-makers, planners, and communities in making sound judgments as to how best manage their water resources for both human use and to minimize impacts to the natural environment.

ArcGIS for Environmental and Water Issues



ArcGIS for Environmental and Water Issues


Introduction


GIS (Geographic Information System) has great value in our time as it is a comprehensive information system evolved and still developing parallel with the advancing technology. This era of the human kind is characterized as an information age,where the whole world is experiencing and interacting with a new revolution that change our traditional way to look at the things and do a business in completely different approach.

Geographic Information Systems in Water Resources Engineering





Preface 


Geographic information systems (GIS) are strongly impacting the fields of water resources engineering, environmental science, and related disciplines. GIS tools for spatial data management and analysis are now considered state of the art, and application of these tools can lead to improved analyses and designs. Familiarity with this burgeoning technology may be a prerequisite for success in our efforts to create reliable infrastructure and sustain our environment. 








GIS is rapidly changing the ways that engineering planning, design, and management of water resources are conducted. Advances in data-collection technologies—using microprocessor-based data-collection platforms and remote sensing—provide new ways of characterizing the water environment and our built facilities. Spatial databases containing attribute data and imagery over time provide reliable and standardized archival and retrieval functions, and they allow sharing of data across the Internet. GIS analysis functions and linked mathematical models provide extensive capabilities to examine alternative plans and designs. 


Map-oriented visualizations in color, three-dimensional, and animation formats help communicate complex information to a wide range of participants and interest groups. Moreover, interactive GIS database and modeling capabilities permit stakeholders to participate in modeling activities to support decision making. GIS is an all encompassing set of concepts and tools that provides a medium for integrating all phases of water resources engineering planning and design




This book provides relevant background on GIS that is useful in understanding its advanced applications in water resources engineering. The book has been developed with two primary sections. For the first part of the book (Chapters 1–4), the emphasis is on developing an understanding of the nature of GIS, recognizing how a GIS is used to develop and analyze geographic data, differentiating between the various types of geographic data and GISs, and summarizing data development and database concepts. Primary field-data collection and methods of interpretation and analysis are also introduced. 


The second part of the book (Chapters 5–12) focuses on the various subdomains of water resources engineering, the data involved, linkage of GIS data with water resource analysis models, and management applications. Applications include watershed hydrologic and groundwater modeling, water and wastewater demand forecasting, pipe network modeling, nonpoint sources of water pollution, floodplain delineation, facilities management, water resources monitoring and forecasting, and river-basin management decision-support systems. The applications include descriptions of GIS database development, analysis background theory, and model integration with the GIS



The chapter titles in the book are as follows: 


1. Introduction 

2. Introduction to Geographic Information Systems 

3. GIS Data and Databases 4. GIS Analysis Functions and Operations 

5. GIS for Surface-Water Hydrology 

6. GIS for Groundwater Hydrology 

7. GIS for Water-Supply and Irrigation Systems 


8. GIS for Wastewater and Stormwater Systems 

9. GIS for Floodplain Management 

10. GIS for Water Quality 


11. GIS for Water Resources Monitoring and Forecasting 

12. GIS for River Basin Planning and Management



At the end of each chapter there is a list of references related to the specific topic covered in that chapter. The GIS literature is large and growing rapidly, and relevant works are found in a diversity of sources. Some are found in refereed journals of civil engineering, water resources, and planning. Other works are found in government agency publications, academic programs, and on Web sites for both. Although the collected references and Web links are considered a valuable resource, I make no claim that it is comprehensive. For many readers, the references listed will be sufficient; for others wishing to go farther, they will serve only as a beginning.

Groundwater Resource Evaluation

Resource Evaluation, Augmentation, Contamination, Restoration, Modeling and Management

Ground Water

Preface of the Book
Groundwater plays a major role in the livelihood of mankind by providing water for drinking, irrigation and industrial purposes. The rapid population growth in the last three decades all over the globe resulted in exploiting more groundwater. The distribution of groundwater—both in space and time— is more erratic as it depends on the subsurface geological and climatic conditions. In many countries, the decline of water level indicates that the resources are depleted very fast. 

It is, therefore, necessary to assess the available subsurface resource in a more judicious scientific manner and then apply it for evolving optimal utilization purposes. There is an urgent need to have a comprehensive book, which contains the entire spectrum of groundwater assessment and management aspects. I had seen many books, which cover only the specific aspects on groundwater exploration, exploitation, augmentation, pollution and remediation and mathematical modeling but not many books on the integrated aspects of all. It was, therefore, planned to bring a book, which covers the above said aspects by inviting specific topics from various experts of the globe.

Hydrology in Practice

Hydrology in Practice

Third edition , Elizabeth M.Shaw Formerly of the Department of Civil Engineering Imperial College of Science, Technology and Medicine  




Preface to the Third Edition 
In the current critical concern for the well-being of the environment, hydrologists in practice are finding the need for information on many more related topics.
The course contents in universities and other training establishments are developing a wider appreciation of the scope of hydrology and requests for the inclusion of such allied subjects as climatic change, sediment transport and catchment morphometry have been indicated. Without changing the structure of the text, brief introductions to these subjects with accompanying references have been inserted where practicable.
The major revisions have resulted from the technological advances in instrumentation and the philosophical changes in data processing. The original aims in handling hydrological measurements were to automate quality control and analysis with complex statistical programs on large-capacity mainframe computers. With desktop personal microcomputers, linked to field instruments and mainframe, the skilled meteorologist or hydrologist can make experienced subjective judgement on the data from elaborate displays of back-up related information.
