Book Synopsis Digital Terrain Modeling and Distributed Soil Erosion Simulation/measurement for Minimizing Environmental Impacts of Military Training by : Steven D. Warren
Download or read book Digital Terrain Modeling and Distributed Soil Erosion Simulation/measurement for Minimizing Environmental Impacts of Military Training written by Steven D. Warren and published by . This book was released on 1998 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because soil erosion and deposition have negative repercussions on military preparedness and the environment, the Strategic Environmental Research and Development Program (SERDP) has funded efforts to develop geographic information system (GIS) tools and methods to enhance the accuracy, spatial prediction, and visual representation of erosion and deposition on military lands. During Fiscal Year 1997, the CASC2D model was modified to include an upland erosion algorithm. The modified model produced accurate runoff hydrographs, but fell short in predicting sediment discharge. Part of the inaccuracy is attributable to channel erosion not taken into account by the current CASC2D model. The Unit Stream Power Erosion and Deposition (USPED) model was enhanced to include tangential curvature. The modification greatly improves the accuracy of erosion and deposition predictions in areas of convergent slopes. The process-based SIMulated Water Erosion (SIMWE) model was used to investigate the effects of rainfall excess, surface roughness, critical shear stress, detachment capacity, and transport capacity on erosion and deposition. Results of initial investigations conducted to determine if the SIMWE model could be used to predict the consequences of common erosion and sediment control practices were promising. Various GIS tools were developed to help in processing and visualization of distributed data.

This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recognition of the negative repercussions that soil erosion and sediment deposition can have on military preparedness and the environment, the Strategic Environmental Research and Development Program (SERDP) funded a research effort between Fiscal Years 1993 and 1998 to develop geographic information system (GIS) tools and methods to enhance the accuracy, spatial prediction and visual representation of erosion and deposition on military lands. Because of the variability in the quality and availability of data to support erosion/deposition modeling efforts, the project sought to enhance both relatively simple empirical models and more data-intensive process-based models. In addition, the project addressed the demands for long-term average annual estimates of erosion/deposition and single event-based predictions.
Book Synopsis Landscape Erosion and Evolution Modeling by : Russell S. Harmon
Download or read book Landscape Erosion and Evolution Modeling written by Russell S. Harmon and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landscapes are characterized by a wide variation, both spatially and temporally, of tolerance and response to natural processes and anthropogenic stress. These tolerances and responses can be analyzed through individual landscape parameters, such as soils, vegetation, water, etc., or holistically through ecosystem or watershed studies. However, such approaches are both time consuming and costly. Soil erosion and landscape evolution modeling provide a simulation environment in which both the short- and long-term consequences of land-use activities and alternative land use strategies can be compared and evaluated. Such models provide the foundation for the development of land management decision support systems. Landscape Erosion and Evolution Modeling is a state-of-the-art, interdisciplinary volume addressing the broad theme of soil erosion and landscape evolution modeling from different philosophical and technical approaches, ranging from those developed from considerations of first-principle soil/water physics and mechanics to those developed empirically according to sets of behavioral or empirical rules deriving from field observations and measurements. The validation and calibration of models through field studies is also included. This volume will be essential reading for researchers in earth, environmental and ecosystem sciences, hydrology, civil engineering, forestry, soil science, agriculture and climate change studies. In addition, it will have direct relevance to the public and private land management communities.

Book Synopsis Environmental Applications of Digital Terrain Modeling by : John P. Wilson
Download or read book Environmental Applications of Digital Terrain Modeling written by John P. Wilson and published by John Wiley & Sons. This book was released on 2018-02-15 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: A digital elevation model (DEM) is a digital representation of ground surface topography or terrain. It is also widely known as a digital terrain model (DTM). A DEM can be represented as a raster (a grid of squares) or as a vector based triangular irregular network (TIN). DEMs are commonly built using remote sensing techniques, but they may also be built from land surveying. DEMs are used often in geographic information systems, and are the most common basis for digitally-produced relief maps. The terrain surface can be described as compromising of two different elements; random and systematic. The random (stochastic) elements are the continuous surfaces with continuously varying relief. It would take an endless number of points to describe exactly the random terrain shapes, but these can be described in practice with a network of point. It is usual to use a network that creates sloping triangles or regular quadrants. This book examines how the methods and data sources used to generate DEMs and calculate land surface parameters have changed over the past 25 years. The primary goal is to describe the state-of-the-art for a typical digital terrain modeling workflow that starts with data capture, continues with data preprocessing and DEM generation, and concludes with the calculation of one or more primary and secondary land surface parameters. Taken as a whole, this book covers the basic theory behind the methods, the instrumentation, analysis and interpretation that are embedded in the modern digital terrain modeling workflow, the strengths and weaknesses of the various methods that the terrain analyst must choose among, typical applications of the results emanating from these terrain modeling workflows, and future directions. This book is intended for researchers and practitioners who wish to use DEMs, land surface parameters, land surface objects and landforms in environmental projects. The book will also be valuable as a reference text for environmental scientists who are specialists in related fields and wish to integrate these kinds of digital terrain workflows and outputs into their own specialized work environments.

Book Synopsis Modeling the Complex Dynamics of Landscape Development: Applications for Land Management by :
Download or read book Modeling the Complex Dynamics of Landscape Development: Applications for Land Management written by and published by . This book was released on 2004 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Erosion on military lands limits Army training activities, and may cause environmental problems both at training sites and downstream. Thus, remedial soil and land conservation plans are vitally important to stabilize erosion and use the land more safely for Army activities while complying with environmental regulations and standards. The channel-hillslope integrated landscape development (CHILD) model is a dynamic, physically based, spatially distributed numerical framework for modeling soil erosion and landscape evolution, originally developed at MIT. Potential uses of CHILD include understanding the sensitivity of earth surface to changes in climate, land cover conditions and anthropogenic disturbances. In this paper, we present recent advances in the CHILD model with example numerical simulations. These are the effects of vegetation-erosion coupling on the short and long-term response of erosion rates and landscape topography, and modeling gully development by plunge-pool erosion at the gully head and widening by bank failures. CHILD simulations using a dynamic plant growth component show vegetation loss as an important factor accelerating erosion rates in decadal time scales. Over the long term, vegetation may change the dominant erosion process on the landscape, create episodicity in the sediment yields, and alter the visual appearance of landforms. Landscapes modeled using the new gully erosion module in CHILD produce landforms that compare well with the observed gullies in the Army training areas in Fort Carson and Pinon Canyon Maneuver Sites in Colorado. These results show potential applicability of the model for short and long-term land management purposes in the army lands.
Book Synopsis Assessment of Cumulative Training Impacts for Sustainable Military Land Carrying Capacity and Environment by : Steven William Singer
Download or read book Assessment of Cumulative Training Impacts for Sustainable Military Land Carrying Capacity and Environment written by Steven William Singer and published by . This book was released on 2010 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States Army land managers are facing a difficult task of balancing environmental quality and military land carrying capacity when planning missions. The increase in soil erosion and landscape fragmentation caused by intensive military training degrades environmental quality and restricts military missions simultaneously. This study aims at overcoming the existing gaps in land management of the U.S. Army installations. The significant contributions made in this study include (i) exploring the relationships of landscape aesthetic evaluations with spatial metrics variables and further incorporating the spatial metrics as surrogates of the landscape aesthetic evaluations into derivation of comprehensive environmental quality indicator; and (ii) developing a practical method to integrate the individual factors into a comprehensive environmental quality indicator at both landscape and patch levels based on sustainable environmental health and military land carrying capacity.
Book Synopsis Evaluation of Technologies for Addressing Factors Related to Soil Erosion on DOD Lands by :
Download or read book Evaluation of Technologies for Addressing Factors Related to Soil Erosion on DOD Lands written by and published by DIANE Publishing. This book was released on 1997 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Defense (DOD) is currently moving towards the concept of "ecosystem management" to more effectively protect, sustain, and/or enhance natural and cultural resources critical to the training mission. Ecosystem management is an approach to natural resources management that recognizes the interrelationships of ecological processes that link soils, plants, animals, minerals, climate, water, and topography as a living system. This system is important to and is affected by human activity beyond traditional commodity and amenity uses and acknowledges the importance of ecosystem services such as water conservation, oxygen recharge, and nutrient recycling. Some of the factors that must be considered in ecosystem management include the effects of soil erosion on water and air quality, potential damage to wildlife habitat, and in the case of DOD, the effects on the ability to train efficiently and effectively.
