Available in PDF, EPUB and Kindle. Book excerpt: Erosion following wildfire can be as much as 1000 times the erosion from an undisturbed forest. In August, 2005, the largest fire in the lower 48 states occurred in the Umatilla National Forest in Southeast Washington. Researchers from the Rocky Mountain Research Station assisted the forest in estimating soil erosion using three different applications of the WEPP model. GeoWEPP was used to determine the onsite distribution of soil erosion. WEPP Windows Watershed Version was used to estimate peak runoff rates of each of the ten small watersheds analyzed. The ERMiT interface to WEPP was used to estimate the probability of erosion amounts on selected hillslopes, and the benefits of mulching those slopes. Within the three days available for analysis, about 38 percent of the burned area was analyzed. This paper summarizes the analytical methods, and the findings of the prediction runs.

This book was released on 2018 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cascading consequences of fire-induced ecological changes have profound impacts on both natural and managed forest ecosystems. In many areas, natural and human-caused wildland fire are becoming more prevalent due to historical management practices exacerbated by climate change . The susceptibility of landscapes to post-fire soil erosion and runoff have been closely linked with the severity of the wildfire, and forest managers tasked with implementing mitigation strategies need robust tools to evaluate the effectiveness of their decisions, particularly those affecting hydrological recovery. Various hillslope-scale interfaces of the physically-based Water Erosion Prediction Project (WEPP) model have been successfully validated for this purpose using fire-effected plot experiments, however these interfaces are explicitly designed to simulate single hillslopes. Spatially-distributed, catchment-scale WEPP interfaces have been developed over the past decade, however none have been validated for post-fire conditions, posing a barrier to adoption for forest managers. The work proposed here will address concerns of model validity by developing new processing frameworks which enhance the ability of the spatial WEPP model to capture hillslope-scale patterns in burn severity. These methods will be applied to compare simulations results with five years of post-fire runoff and erosion observations for a 117 ha forested watershed after the 2011 Wallow Fire in Eastern Arizona. Further, visualization strategies will be developed and implemented into current online spatial WEPP interfaces which facilitate usability and adoption of such models .

Available in PDF, EPUB and Kindle. Book excerpt: The movement of sediment and associated pollutants over thelandscape and into water bodies is of increasing concern withrespect to pollution control, prevention of muddy floods andenvironmental protection. In addition, the loss of soil on site hasimplications for declining agricultural productivity, loss ofbiodiversity and decreased amenity and landscape value. The fate ofsediment and the conservation of soil are important issues for landmanagers and decision-makers. In developing appropriate policiesand solutions, managers and researchers are making greater use oferosion models to characterise the processes of erosion and theirinteraction with the landscape. A study of erosion requires one to think in terms ofmicroseconds to understand the mechanics of impact of a singleraindrop on a soil surface, while landscapes form over periods ofthousands of years. These processes operate on scales ofmillimetres for single raindrops to mega-metres for continents.Erosion modelling thus covers quite a lot of ground. This bookintroduces the conceptual and mathematical frameworks used toformulate models of soil erosion and uses case studies to show howmodels are applied to a variety of purposes at a range of spatialand temporal scales. The aim is to provide land managers and otherswith the tools required to select a model appropriate to the typeand scale of erosion problem, to show what users can expect interms of accuracy of model predictions and to provide anappreciation of both the advantages and limitations of models.Problems covered include those arising from agriculture, theconstruction industry, pollution and climatic change and range inscale from farms to small and large catchments. The book will alsobe useful to students and research scientists as an up-to-datereview of the state-of-art of erosion modelling and, through aknowledge of how models are used in practice, in highlighting thegaps in knowledge that need to be filled in order to develop evenbetter models.

Available in PDF, EPUB and Kindle. Book excerpt: There can be little doubt that issues relating to soils and sediments are moving up the political agenda, and a realization that we need to collectively manage and protect both soil and water resources. In order to manage this delicate interface, attention is being increasingly directed towards holistic land-river management, demanding a greater appreciation of the interaction between soils and sediments. This book reviews the major achievements recently made in soil erosion and sediment redistribution research and management, and identifies future requirements.

Download or read book Predicting Rainfall Erosion Losses written by Walter H. Wischmeier and published by . This book was released on 1978 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Universal Soil Loss Equation (USLE) enables planners to predict the average rate of soil erosion for each feasible alternative combination of crop system and management practices in association with a specified soil type, rainfall pattern, and topography. When these predicted losses are compared with given soil loss tolerances, they provide specific guidelines for effecting erosion control within specified limits. The equation groups the numerous interrelated physical and management parameters that influence erosion rate under six major factors whose site-specific values can be expressed numerically. A half century of erosion research in many States has supplied information from which at least approximate values of the USLE factors can be obtained for specified farm fields or other small erosion prone areas throughout the United States. Tables and charts presented in this handbook make this information readily available for field use. Significant limitations in the available data are identified.

Available in PDF, EPUB and Kindle. Book excerpt: The decision of where, when, and how to apply the most effective post-fire erosion mitigation treatments requires land managers to assess the risk of damaging runoff and erosion events occurring after a fire. To aid in this assessment, the Erosion Risk Management Tool (ERMiT) was developed. This user manual describes the input parameters, input interface, model processing, and output files for version 2006.01.18. ERMiT is a web-based application that uses Water Erosion Prediction Project (WEPP) technology to estimate erosion, in probabilistic terms, on burned and recovering forest, range, and chaparral lands with and without the application of erosion mitigation treatments. User inputs are processed by ERMiT to combine rain event variability with spatial and temporal variabilities of soil burn severity and soil properties, which are then used as WEPP input parameters. Based on 20 to 40 individual WEPP runs, ERMiT produces a distribution of rain event sediment delivery rates with a probability of occurrence for each of five post-fire years. In addition, event sediment delivery rate distributions are generated for post-fire hillslopes that have been treated with seeding, straw mulch, and erosion barriers such as contour-felled logs or straw wattles.
