Book Synopsis Watershed Erosion Processes by : Tongxin Zhu
Download or read book Watershed Erosion Processes written by Tongxin Zhu and published by Springer Nature. This book was released on 2021-09-29 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is a fundamental study of watershed erosion and runoff processes. It utilizes decades of soil erosion data to take a comprehensive and balanced approach in covering various watershed erosion processes. While there are many works on soil erosion and conservation, this book fills the gaps in previously published research by focusing more on mass movement, gully erosion, soil piping/tunnel erosion, and the spatial interactions of different erosion processes. Additionally, the book examines erosion processes in extreme rainfall events, something typically absent in short-term studies but discussed in detail here as the book draws on 60 years of research and observations, including 30 years of the author's own investigations of erosion under a wide range of rainfall conditions. The book is divided into 3 parts, and is intended for soil erosion researchers and practitioners, and postgraduate students studying soil erosion and water conservation. Part 1 opens with a comprehensive and critical review of existing literature on soil erosion processes, discusses this book's place among existing literature, and examines the major erosion processes (rainwash, gully erosion, tunnel erosion, and mass movements) including their controlling factors and mechanisms. Part 2 explores the spatial interactions of these different erosion processes to provide a prerequisite for effective design of comprehensive soil erosion control measures in a watershed. Part 3 evaluates the relative significance of these erosion processes in sediment production, the effectiveness of comprehensive soil and water conservation programs, and the applications of watershed modelling in determining the impact of land-use changes on soil erosion and other ecological processes.

The meeting was also one of a series organised by the IGBP 1 GCTE Soil Erosion Network, which is a component of GCTE's Land Degradation Task (3.3.2) (Ingram et aI., 1996; Valentin, this volume). One aim of the GCTE Soil Erosion Network is to evaluate the suitability of existing soil erosion models for predicting the possible impacts of global change upon soil erosion. Due to the wide range of erosion models currently, in use or under development, it was decided to evaluate models in the following sequence Favis-Mortlock et al., 1996): • field-scale water erosion models • catchmenr-scale water erosion models • wind erosion models • models with a landscape-scale and larger focus. As part of this strategy, the first stage of the GCTE validation of field-scale erosion models was carried out at the Oxford NATO-ARW. I A list of Acronyms fonns Appendix A.

Book Synopsis Predicting Rainfall Erosion Losses by : Walter H. Wischmeier
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.
Book Synopsis Assessment of Sediment Yield Using USLE and GIS at Small Watersheds by : Mohsan Mehdi
Download or read book Assessment of Sediment Yield Using USLE and GIS at Small Watersheds written by Mohsan Mehdi and published by LAP Lambert Academic Publishing. This book was released on 2013-01 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil erosion is causing degradation and loss of the critical natural resources necessary for the sustenance of human life on the planet. It is a serious problem in arid and semi-arid zones like Pakistan due to sparse vegetation and high rain intensities mainly concentrated in monsoons seasons. Pakistan has many potential sites for hydropower projects, but sediment discharge data is not available at many locations for the estimation of reservoir life etc. Present study is designed to focuses on soil erosion and sediment yield estimation using USLE and GIS at small watershed scale. Results of the model can be used to predict the sediment inflow to the reservoirs. Model shows that USLE underestimated sediment yield by 40 to 60% as compared to the observed sediment yield. The obvious reason is that USLE is an empirical equation and does not consider the transfer of mass and energy within the watershed, however for watershed scale modelling this accuracy is enough to explain the soil erosion and sediment yield characteristic of the watershed.
Book Synopsis Spatial Techniques for Soil Erosion Estimation by : Rupesh Jayaram Patil
Download or read book Spatial Techniques for Soil Erosion Estimation written by Rupesh Jayaram Patil and published by Springer. This book was released on 2018-02-16 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a novel computation of the topographic LS factor of the USLE model to estimate spatial soil erosion. In developing countries, soil erosion is one of the main concerns as it adversely affects agriculture and reduces food production. Therefore, the author presents a particularly relevant approach, as he demonstrates how the C++ programming allows us to identify important erosion stages like detachment and deposition. He does this by assessing the annual rate of soil erosion from the Shakkar River watershed in India using distributed information and applying RS and GIS techniques. He also discusses different approaches that have been proposed to work out the influence of topography on erosion. Simulated and observed data of sediment loss are compared for the period 1992 to 2006.This book provides an easy-to-understand basic piece of soil erosion and hydrological research and reaches out to young researchers and students at the graduate and undergraduate level as well as applicants of soil erosion models.
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.

This book was released on 2016-10-31 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2015 in the subject Geography / Earth Science - Physical Geography, Geomorphology, Environmental Studies, grade: 1.0, Central Mindanao University (College of Forestry and Environmental Science), course: Bachelor of Science in Forestry, language: English, abstract: The Geospatial Water Erosion Prediction Project (GeoWEPP v10.2) was tested using data from field survey in three study site within Taganibong Watershed, Bukidnon. This field survey data such as waypoints and soil data was processed and edited through ArcGIS software to prepare for model simulation. Weather information were collected using Automatic Weather Station on an hourly basis at the study site. Climate data was created using Breakpoint Climate Data Generator (BPCDG) which allows direct use of observed storm and other daily standard climate datasets. Model simulation was applied in three land cover to evaluate their abilities in reducing runoff and their effects on other water balance parameters. For the study area, the bamboo area with undisturbed harvesting practices has more effective way in reducing surface runoff based on the results of model simulation. On the other hand, the cultivated area (corn) produce highest surface runoff due to the exposure of soil after harvesting period. Statistical analysis was applied to determine the effects of different land cover to the amount of water balance given the amount of rainfall in monthly basis. Magnitude of rainfall as the primary input to water balance has a huge effects in return to hydrologic processes (percolation, soil water, subsurface lateral flow, etc). This study provides a theoretical basis and technical support for land use zoning, policy implementation, soil and water conservation in upland watersheds.

This book was released on 2008 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil erosion is a problem that causes both the loss of valuable soil and water quality degradation by sediment and attached nutrients and pollutants. Soil loss and sediment discharge to waterbodies can be prevented and mitigated by best management practices (BMPs). The USDA-NRCS reported that BMPs such as filter strips and grassed waterways can reduce up to 50 to 70% of the runoff and sediment leaving agricultural land. This study includes measured data analyses and representation of BMPs such as row cropping, filter strips and grassed waterways in a small experimental watershed (2.09 ha) at Nelson Farm, MS. Row cropping was conducted throughout a study period from 1990 to 1995 (6 years). Filter strips and grassed waterways were implemented in October 1991 and August 1994, respectively. A total of three phases were established according to the BMP implementation schedule. Phase 1 started from December 1990 to October 1991 with row cropping only, phase 2 started from October 1991 to August 1994 with row cropping and filter strips, and phase 3 started from September 1994 to December 1995 with row cropping, filter strips, and grassed waterway. The WEPP (Water Erosion Prediction Project) model and its parameters including physically based parameters are used and adjusted for the representation of BMPs. Input data includes weather data measured by the National Sedimentation Laboratory researchers and staff in Oxford, Mississippi. Management, crop yield, and BMP information in previous studies by Dabney and Meyer were used. Watershed characteristics were derived from a 2 foot contour map using GIS. These watershed characteristics were also found in previous studies. The parameter setting for the vegetative practices were calibrated and validated to agree with observed data at the location of the practices in each phase. There are two WEPP projects depending on two different flow paths, one is based on flow along the cropping row and the other is based on flow over the crop rows when the rows are collapsed by large runoff events after tillage. The Soil and Water Assessment Tool (SWAT) was run with the same watershed properties and parameter settings although there were some parameters not available in SWAT. In general, SWAT estimated larger runoff and sediment yields although the difference was small. A possible explanation is that SWAT uses one representative slope, which is a linear slope, while WEPP uses dynamic slope steepness, which includes convex and concave slope shapes. Another reason is that there is no spatial location for filter strips and no representation for the multiple filter strips is possible in SWAT. The BMP impact analyses (using WEPP) estimate the reduction of runoff and sediment yield by each BMP in each phase. The results of these analyses show that row cropping reduced 11.1% of runoff and 15.8% of sediment yield in phase (1) Row cropping and filter strips reduced 14.6% of runoff and 41.9% of sediment yield in phase (2) Row cropping, filter strips, and grassed waterway reduced 20.5% of runoff and 65.7% of sediment yield in phase (3) Total reduction by all BMPs installed according to their schedule during the study period was 14.3% of runoff and 38.5% of sediment yield. Various scenario analyses have been conducted. These include the failure of BMPs, the effectiveness of a combination of BMPs, the long-term impacts of BMPs, and the spatially distributed estimation of the effectiveness of filter strips. BMP failure analysis was conducted for filter strips and grassed waterway in each phase based on the parameter value adjustment by 25%, 50%, 75%, and 100% from the range of possible parameter values. In phase 2, with filter strips, the results of filter strips failure analysis show the reduction of runoff ranges from -4.2% (best) to +0.6% (no function) and that of sediment yield ranges from -29.6% (best) to +14.0% (no function). There would be more runoff and sediment yield generated than observed when the filter strips are not maintained because there is no vegetation on filter strips. In phase 3, with filter strips and a grassed waterway, the results of failure analysis show the reduction of runoff ranges from -2.1% (best) to +12.1% (no function) and that of sediment yield ranges from -14.3% (best) to +138.1% (no function). For the same reason, the runoff and sediment yield were larger in the 'no function' scenario than observed. (Abstract shortened by UMI.).
