This study was conducted to investigate the effect of slope gradient and soil physical properties (grain size distribution, bulk density, aggregate stability and permeability) on water erosion in the furrows of rainfed farms under fallow conditions. The furrows with 6 m length were installed in five rainfed farms with 6.1, 10.6, 14.8, 20.7 and 27.1% slope steepness at three replications. Resul...

The present study was conducted in Mollaahmad watershed of Ardabil city in 1390 to evaluate the canonical correlation between tillage erosion [slope gradient and position], and grain yield and barley yield components (Sahand cultivar) in order to determine the covariability between the two sets of variables to (1) detect simultaneously occurring patterns in the interdependencies sets of canonic...

Soil erosion by surface runoff introduced as surface erosion is one of the main mechanisms of land degradation in the hill slopes. Slope characteristics including aspect and gradient can control the differences of soil properties along the hillslope. This study was conducted to investigate the effect of slope aspect and gradient on variations of some soil properties in the short slopes. Five hi...

generally, the evaluation and assessment critical condition of rill formation are useful for a better understanding of soil erosion processes. the inherence characteristics of soils, which have much dynamic variations on the hill-slopes and are affected by rill formation, are the soil critical shear stress and soil erodibility factors. this study aims to assess experimental rill incision thresh...

This study was conducted to investigate the temporal variations of runoff and rill erosion in various soil textures under different slope gradients. So, a laboratory experiment was set up in three soil textures (loam, clay loam, and sandy clay loam) and four slope gradients (5, 10, 15, and 20%) using the completely randomized design with three replications. Runoff production and rill erosion we...

nt matter & 2007 IAgrE. emseng.2007.07.007 hor. : [email protected] (B. Li) A concrete slatted floor system that consists of a narrow-gap slatted floor and beneath it a slope bottom for separation of faeces and urine in pig houses was investigated. In the experiments, four concrete slatted floors with one of two slat profiles and one of two gap widths, and a steel wire slatted floor were studied ...
