Written for hydrologists, GIS specialists, and scientists from many disciplines who create computer models of water resources, this book presents an improved standard for creating and using data in hydrologic projects. The ArcGIS hydro data model is the latest innovation in GIS modeling and increases the potential to integrate data from many sources to solve a wider range of water resource problems. This guide shows how hydrology projects work and how they can work better: by integrating local, regional, national, and international data to create a deeper understanding of the earth's water problems.

Arc Hydro Groundwater: GIS for Hydrogeologydescribes the groundwater data model, a new geodatabase design for representing groundwater systems using ArcGIS software. The groundwater data model shares a common framework with the surface water components of the Arc Hydro data model, offering a comprehensive overview of water resources.Arc Hydro Groundwateruses sample datasets from the Edwards Aquifer and other locations in Texas to address the data model framework, 3D subsurface representation, geological mapping, 3D hydrogeologic models, time series for hydrologic systems, and groundwater simulation models.

State-of-the-art GIS spatial data management and analysis tools are revolutionizing the field of water resource engineering. Familiarity with these technologies is now a prerequisite for success in engineers’ and planners’ efforts to create a reliable infrastructure. GIS in Water Resource Engineering presents a review of the concepts and applications of GIS in the various sub-fields of water resource engineering. After a summary review of analyses and database functions, the book addresses concepts and applications in the following areas: Surface Water Hydrology Groundwater Hydrology Water Supply and Irrigation systems Wastewater and Stormwater Systems Floodplain Management Water Quality Water Resource Monitoring and Forecasting River Basin Planning and Management The book develops a general understanding of the nature of GIS and how it is used to create and analyze geographic data. The author first introduces primary field data collection methods and describes procedures for interpretation and analysis. The second portion of the book focuses on the linkage of GIS data with water resource analysis and management models. Applications are presented with descriptions of GIS database development, analysis background theory, and model integration with GIS. The profound impact of GIS systems on water resources engineering continues to grow. GIS in Water Resource Engineering arms engineers and planners with an arsenal of tools to assist in the creation of a reliable, environmentally sensitive, infrastructure.

This guide to creating a dynamic GIS data model helps database managers design a schema that has comprehensive and descriptive query definitions, a user-friendly cartographic display, and increased performance standards. The five steps for taking a data model through its conceptual, logical, and physical phases, including modeling the user's view, defining objects and relationships, selecting geographic representations, matching geodatabase elements, and organizing the geodatabase structure are studied in detail. A look at nine decision points that deal with concerns common to all data modeling exercises, such as validating feature geometries, modeling linear networks, managing raster data, and labeling map features help database managers fine-tune their GIS data models. Several design models for a variety of applications are considered including addresses and locations, census units and boundaries, stream and river networks, and topography and the base map.

This unique book focuses on remote sensing (RS) and geographical information systems (GIS) in Iraq. The environmental applications include monitoring and mapping soil salinity and prediction of soil properties, monitoring and mapping of land threats, proximal sensing for soil monitoring and soil fertility, spatiotemporal land use/cover, agricultural drought monitoring, hydrological applications including spatial rainfall distribution, surface runoff and drought control, geo-morphometric analysis and flood simulation, hydrologic and hydraulic modelling and the effective management of water resources. Also, this book assesses the impacts of climate change on natural resources using both RS and GIS, as well as other applications, covering different parts of Iraq. The book chapters include tens of maps extracted from the remotely sensed datasets, in addition to tables and statistical relations obtained from the results of the studies of the chapters' authors. These studies have been conducted in different parts of Iraq; in the north (Kurdistan region) with its mountainous and undulating lands, in western parts which have desert soils, and in central and southern Iraq where there are salty soils, dunes, wetlands, and marshes. The book is written by distinguished scientists from Iraq, China, USA, Italy, Iran, Germany, and the Czech Republic who are interested in the Iraqi environment. The book is therefore a useful source of information and knowledge on Iraqi environment for graduate students, researchers, policy planners, and stakeholders in Iraq as well as similar regions.

The late Professor Reds Wolman in his Foreword to the award-winning second edition said, "This is not your ordinary textbook. Environmental Hydrology is indeed a textbook, but five elements often found separately combine here in one text to make it different. It is eclectic, practical, in places a handbook, a guide to fieldwork, engagingly personal and occasionally opinionated. ... and, perhaps most engaging to me, in places the authors offer personal views as well as more strongly worded opinions. The former often relate to evaluation of alternative approaches, or formulations, of specific solutions to specific hydrologic problems." The first and second editions were bestsellers and the third promises to educate people new to the field of hydrology and challenge professionals alike, with insightful solutions to classical problems as well as trendsetting approaches important to the evolving genre. The third edition enhances materials in the second edition and has expanded information on many topics, in particular, evapotranspiration, soil erosion, two-stage ditch design and applications, and stream processes. What’s New in the Third Edition: Presents new sections on rock structures in streams, hypoxia, harmful algal blooms, and agricultural practices to reduce nutrient discharges into water resources Enhances the format to aid the reader in finding tables, figures, and equations Contains more than 370 figures, 120 tables, 260 equations, 100 worked examples, 160 problems, and more than 1000 references Collectively, the authors have more than 130 years of international experience and the addition of John Lyon and Suzette Burckhard as co-authors expands the breadth of knowledge presented in this book. More than 60 scientists and engineers in Australia, Canada, Europe, and the United States provided assistance to round out the offerings and ensure applicability to hydrology worldwide.
