GIS for Water Resources and Watershed Management
"GIS for Water Resources and Watershed Management" by John G. Lyon is a comprehensive book that explores the application of Geographic Information Systems (GIS) in managing water resources and watersheds. The book covers various topics and case studies that demonstrate the use of GIS in analyzing and understanding water-related issues.
The book begins with an introduction by John G. Lyon, providing an overview of the importance of GIS in water resources and watershed management. It sets the stage for the subsequent chapters that delve into specific techniques and applications.
Chapter 1, authored by Lawrence W. Martz and Jurgen Garbrecht, focuses on channel network delineation and watershed segmentation using the TOPAZ Digital Landscape Analysis System. It discusses the methodology and tools used to identify and analyze channel networks within a watershed.
Chapter 2, written by Jurgen Garbrecht and Lawrence W. Martz, explores the assessment of automated watershed segmentation from digital elevation models. The chapter examines the performance of automated techniques in accurately delineating watersheds using elevation data.
Chapter 3, authored by Yasuto Tachikawa, Michiharu Shiiba, and Takuma Takasao, presents the development of a Basin Geomorphic Information System using a TIN-DEM (Triangular Irregular Network-Digital Elevation Model) data structure. The chapter discusses the utilization of this system to analyze and understand basin geomorphology.
In Chapter 4, Craig A. Harvey and David A. Eash introduce Basinsoft, a computer program designed to quantify drainage basin characteristics. The authors demonstrate how Basinsoft can be utilized to assess various basin attributes and aid in watershed management.
Chapter 5, by Scott N. Miller, D. Phillip Guertin, and David C. Goodrich, focuses on deriving stream channel morphology through GIS-based watershed analysis. The chapter explores the integration of GIS and hydrological modeling techniques to understand stream channel characteristics.
The following chapters cover a range of topics, including GIS modeling and visualization of water balance, GIS coverages for research watersheds, regional characterization of agroecosystems using remotely sensed data, low flow prediction, and evaluation of estuarine study areas.
Other chapters discuss the application of GIS and remote sensing for watershed assessment, the development of databases for lake ecosystem studies, the use of historical aerial photographs and GIS for wetland analysis, and watershed-based evaluation of salmon habitat.
The book also covers topics such as hydrologic simulation, hydrologic modeling using remotely sensed databases, technological advances in land surface parameterization, aerial photointerpretation of hazardous waste sites, and remote sensing and GIS for site-specific farming.
Each chapter provides detailed insights into the methodologies, tools, and applications of GIS in water resources and watershed management. The case studies and examples presented throughout the book offer practical perspectives on how GIS can be used to address various challenges in this field.
"GIS for Water Resources and Watershed Management" is a valuable resource for researchers, professionals, and students interested in the application of GIS technology in understanding and managing water resources and watersheds.
