Century-long studies on the impacts of forest management in North America suggest sediment can cause major reduction on stream water quality. Soil erosion patterns in forest watersheds are patchy and heterogeneous. Therefore, patterns of soil erosion are difficult to model and predict. The objective of this study is to develop a user-friendly management tool for land managers to design forest m...

Fluvial processes and channel development on landscapes have recently received more attention as designers attempt to establish or replace natural streams on disturbed or degraded sites. Several approaches using similar parameters have been developed to evaluate stream development and erosion processes on natural soils and landscapes. Such approaches include the Manning’s and stream power equat...

A Geographical Information System (GIS) based method is proposed and demonstrated for the identification of sediment source areas and the prediction of storm sediment yield from catchments. Data from the Nagwa and Karso catchments in Bihar (India) have been used. The Integrated Land and Water Information System (ILWIS) GIS package has been used for carrying out geographic analyses. An Earth Res...

The Donghe basin is one of the typical regions with serious water and soil erosion in Kaixian county of China. In this study the spatial distribution variation of soil erosion in Donghe basin is analyzed based on a comprehensive method that integrates SWAT model with a Geographic Information System and remote sensing technologies and the effects of land use changes on soil erosion is also analy...

Penelitian ini dilakukan pada bulan Juli 2017 di sekitar Sub-DAS Batang Limun Kabupaten Sarolangun Provinsi Jambi. bertujuan untuk menghitung laju erosi dan menentukan tingkat bahaya yang terjadi disekitar Sub DAS Limun. Metode digunakan dalam penelitian adalah USLE (Universal Soil Loss Equation) dengan pendekatan Geographic Information System (GIS). Berdasarkan hasil menunjukkan bahwa dari sel...

The activity and kinetics of soil phosphatases are important indicators to evaluate soil quality in specific sites such as the Cerrado (Brazilian Savanna). This study aimed to determine the activity and kinetic parameters of soil phosphatase in Cerrado systems. Soil phosphatase activity was assessed in samples of native Cerrado (NC), no-tillage (NT), conventional tillage (CT) and pasture with B...

Accurate estimation of soil erosion due to water is very important in several environmental contexts, such as the assessment of potential soil loss from cultivated lands and the evaluation of the loss of water storage capacity in reservoirs due to sediment deposition. Several studies have been carried out to build models suitable to quantify the results of erosion processes. These models, calib...

A reliable prediction of event soil loss at the plot scale can be obtained by Universal Soil Loss Equation (USLE)-type models. For Sparacia site (South Italy), USLE-MB model was recently developed, in which effect erosive agent is modeled using rainfall erosivity index USLE a power b1 > 1 runoff coefficient QR. In this investigation, parameterized separately data collected for rill and inter...
