Available in PDF, EPUB and Kindle. Book excerpt: The practice of linking Geographic Information Systems (GIS) software and natural resource models has greatly increased in the recent past. Cheaper and more powerful computing resources have allowed us to build systems that minimize the effort and labor involved in parameterizing simulation models. However, by using computerized means to minimize the effort needed to facilitate model parameterization we have increased the complexity in these links between the two components. We have also increased the amount of knowledge required to build the link and have increased the need to understand the consequences of building the links between two systems. The practice of linking these two components creates new issues that affect both the GIS analyst and the researcher. The goal of this research project has been to develop an application linking GIS-based geo-processing tools developed in the Automated Geospatial Watershed Assessment (AGWA) tool to an internet-based map interface. The application allows a user to develop a management scenario by delineating a watershed based on one or more outlet points. The application uses the delineation and other input data sets to develop input parameter files for a hydrologic model, which then runs and produces output for the user. The development of the application produced many interesting issues, but the one identified as most important in terms of this dissertation research was an issue related to using current software development tools such as the Universal Modeling Language (UML) and software design patterns as a way to communicate about system requirements and system functions between programmers and project stakeholders. This research will examine how these software development tools were used to develop DotAGWA, the consequences of using the tools and an analysis of why these tools may be an important component in developing natural resourceprojects that rely heavily on GIS tools.

This book was released on 1999-01-01 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prepared by the Task Committee on GIS Modules and Distributed Models of the Watershed of ASCE. This report guides professionals in selecting the most advantageous applications of geographic information system (GIS) modules and distributed models for watershed runoff. Recent advances in technology offer hydrologic engineers, watershed managers, and data collection agencies unprecedented capabilities for storing and manipulating data. With the advent of Digital Elevation Models (DEM), Triangulated Irregular Networks (TIN), Digital Line Graphs (DLG), and GIS software, the use of watershed modeling among industry professionals has increased at an incredible rate. With this growth, it is increasingly difficult for practitioners to choose the most effective use of the technology. This report identifies state-of-the-art GIS hydrology analysis software and techniques, as well as GIS types and map projections. It covers data commonly required for hydrologic analysis, limitations of available data, and the integration of watershed hydrological analysis software and GIS techniques. The appendix highlights nine examples of watershed modeling systems, including the Watershed Modeling System (WMS), the Soil and Water Assessment Tool (SWAT), and the Hydrologic Model CASC2D.

Download or read book Appropriate Technologies for Environmental Protection in the Developing World written by Ernest K. Yanful and published by Springer Science & Business Media. This book was released on 2009-02-19 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first edited compilation of selected, refereed papers submitted to ERTEP 2007. The selected papers either dealt with technologies or scientific work and policy findings that address specific environmental problems affecting humanity in general, but more specifically, people and ecosystems in developing countries. It was not necessary for the work to have been done in a developing country, but the findings and results must be appropriate or applicable to a developing country setting. It is acknowledged that environmental research, technology applications and policy implementation have been demonstrated to improve environmental sustainability and protection in several developed economies. The main argument of the book is that similar gains can be achieved in developing economies and economies in transition. The book is organized into six chapters along some of the key themes discussed at the conference: Environmental Health Management, Sustainable Energy and Fuel, Water Treatment, Purification and Protection, Mining and Environment, Soil Stabilization, and Environmental Monitoring. It is hoped that the contents of the book will provide an insight into some of the environmental and health mana- ment challenges confronting the developing world and the steps being taken to address them.

Book excerpt: Get the most up-to-date and comprehensive guide to watershed analysis and management. In Watersheds: Processes, Assessment, and Management, author Paul DeBarry covers aspects of watershed physical processes such as assessing, classifying, and evaluating a watershed; using GIS models for watershed assessment; and effectively planning for future use and demands. He covers precipitation, ecology, geology, soils, geomorphology, hydrogeology, hydrology, water quality, hydraulics, GIS, data collection, planning, and management. And he takes you beyond theory so you learn to apply planning, management, GIS, and hydrologic engineering principles in real-world watershed management. This concise reference manual is ideal whether you're a scientist, biologist, geologist, engineer, planner, administrator, part of a citizens group, or a practitioner seeking to identify what is important in the watershed being studied.
Download or read book Simulation Modeling for Watershed Management written by James Westervelt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: A discussion of the role of modeling in the management process, with an overview of state-of-the-art modeling applications. The first chapters provide a background on the benefits and costs of modeling and on the ecological basis of models, using historical applications as examples, while the second section describes the latest models from a wide selection of environmental disciplines. Since management frequently requires the integration of knowledge from many different areas, both single discipline and multidiscipline models are discussed in detail, and the author emphasizes the importance of understanding the issues and alternatives in choosing, applying, and evaluating models. Land and watershed managers as well as students of forestry, park management, regional planing and agriculture will find this a thorough and practical introduction to all aspects of modeling.

Download or read book Distributed Hydrologic Modeling Using GIS written by Baxter E. Vieux and published by Springer. This book was released on 2016-08-19 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a unified approach for modeling hydrologic processes distributed in space and time using geographic information systems (GIS). This Third Edition focuses on the principles of implementing a distributed model using geospatial data to simulate hydrologic processes in urban, rural and peri-urban watersheds. The author describes fully distributed representations of hydrologic processes, where physics is the basis for modeling, and geospatial data forms the cornerstone of parameter and process representation. A physics-based approach involves conservation laws that govern the movement of water, ranging from precipitation over a river basin to flow in a river. Global geospatial data have become readily available in GIS format, and a modeling approach that can utilize this data for hydrology offers numerous possibilities. GIS data formats, spatial interpolation and resolution have important effects on the hydrologic simulation of the major hydrologic components of a watershed, and the book provides examples illustrating how to represent a watershed with spatially distributed data along with the many pitfalls inherent in such an undertaking. Since the First and Second Editions, software development and applications have created a richer set of examples, and a deeper understanding of how to perform distributed hydrologic analysis and prediction. This Third Edition describes the development of geospatial data for use in Vflo® physics-based distributed modeling.
