Particle size distribution (PSD) is a fundamental physical property of soils. Traditionally, the PSD curve was generated by hand from limited data of particle size analysis, which is subjective and may lead to significant uncertainty in the freehand PSD curve and graphically estimated cumulative particle percentages. To overcome these problems, a log-cubic method was proposed for the generation...

The aim of this research was to determine some erodibility factors, aggregate stability, structure stability and crust formation, in soils located at Ilgaz National Park generate their spatial distribution maps using fifteen different interpolation models GIS medium. For aim, total 151 soil samples were collected from surface (0-20 cm) depth. According analysis results, it determined that most ...

Reduction of species diversity which is a significant threat to the earth has been found more important and has attracted attention among ecologists over recent years. This research was carried out to determine the relationships between plant species diversity indices and soil properties by multivariate regression methods in Jamilabad region, Baft, Kerman province, Iran in 2016. Different sites...

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...

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...
