Soil loss expectation and possible relationships among soil erosion, riparian vegetation and water quality were studied in the São José dos Dourados River basin, State of São Paulo, Brazil. Through Geographic Information System (GIS) resources and technology, Soil Loss Expectation (SLE) data obtained using the Universal Soil Loss Equation (USLE) model were analyzed. For the whole catchment area...

Tropical regions have been considered the world's primary agricultural frontier; however, some physico-chemical deficiencies, such as low soil organic matter content, poor soil structure, high erodibility, soil acidity, and aluminum toxicity, have affected their productive capacity. Lime and gypsum are commonly used to improve soil chemical fertility, but no information exists about the long-te...

Soil erosion is a major problem in arid regions, including the Abha-Khamis watershed Saudi Arabia. This research aimed to identify soil erosional probability using various erodibility indices, clay ratio (CR), modified (MCR), Critical Level of Organic Matter (CLOM), and principle component analysis based index (SEI). To achieve these objectives, study used t -tests an artificial neural network ...

Soil piping has been attributed as a potential mechanism of instability of embankments and streambanks. Limited field work has been conducted on quantifying and modeling pipeflow and internal erosion processes in the field with either natural or artificially created soil pipes. This research utilized an innovative constant-head trench system to conduct constant-head soil pipe experiments in two...

Post-wildfires geological hazards are an emerging problem in many places, including areas not typically associated with these events such as the Alpine Region. Hazards connected post-fire processes debris-flows and flood-type threatens people, infrastructures, services economical activities. Apart from a few examples, there is lack of models available to quantify increase susceptibility result ...

Highlights Very fine sand is the single most important variable for predicting rill and interrill erodibility values. Slope steepness property critical shear erosion. Erodibility prediction equations with best goodness-of-fits have both soil texture mineralogy terms. Equations to predict from texture, organic carbon, cation excha...
