Download Estimating Runoff and Sediment Yield Using Kw-Giuh and Musle Models Book in PDF, Epub and Kindle
In the present study, efforts were made to develop one Kinematic Wave and Geomorphic Instantaneous Unit hydrograph theory based and MUSLE model based rainfall-runoff and sediment yield estimating model for un-gauged/in-adequately gauged micro watersheds. The developed model was tested for its application potential on 3-ecologically diverse micro watersheds in Almora district of Uttaranchal. Proposed model simulated total runoff volumes for three micro watersheds were found to be associated with mean relative errors ranging between 16% to 38%. The developed KW-GIUH-MUSLE model was also tested for its potential to give realistic sediment yield estimates for 11 storms/events in a test micro- watershed. It was observed that these sediment yield estimates were associated with about 6% mean relative error and 0.94 mean DV value. The above analysis could thus clearly show that the developed KW-GIUH-MUSLE model can indeed be utilized for obtaining reasonable surface runoff and sediment yield estimates.

Download Spatial Techniques for Soil Erosion Estimation Book in PDF, Epub and Kindle
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.

Download Modeling Runoff and Sediment Yield from a Terraced Watershed Using WEPP Book in PDF, Epub and Kindle
The watershed version of WEPP (Water Erosion Prediction Project) was used to estimate 50-year runoff and sediment yields for a 291 ha watershed in eastern Nebraska that is 90% terraced and which has no historical gage data. The watershed has a complex matrix of elements, including terraced and non-terraced subwatersheds, multiple combinations of soils and land management, a grassed-waterway network, and natural stream channels leading to the outlet. The objectives of this study were to model the study watershed using WEPP and to evaluate model results compared to literature values. WEPP estimated the sediment yield to be 1.9 T/ha/yr, the sediment delivery ratio to be 0.22 and the percent of sediment contribution from the main channel to be 31% of the total sediment yield. These results are consistent with values reported in the literature.

Download Assessment of Sediment Yield Using USLE and GIS at Small Watersheds Book in PDF, Epub and Kindle
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.

Download Development of a Procedure to Estimate Runoff and Sediment Transport in Ephemeral Streams Book in PDF, Epub and Kindle
A distributed hydrologic model for application on small, semiarid watersheds is developed. The distributed model incorporates simplified routing schemes to include the influence of transmission losses on runoff. A sediment transport model, by sediment size fractions, is developed to compute transport capacity and sediment yield in noncohesive, alluvial channels. Based on available information published in soils and topographic maps and on channel and bed sediment characteristics, the procedure is used to estimate runoff rates and amounts together with sediment yields from semiarid watersheds. Example applications include flood frequency analysis and sediment yield. The procedure requires a minimum of observed data for calibration and is designed for practical applications.
