Runoff generation and soil erosion processes after clear cutting

Investigating the Effect of Surface Gravel Cover on Runoff and Soil Erosion with Simulating Runoff

Surface gravel cover is an important factor for contoroling of soil erosion in dry area specially in area that plant can not grow because of excessive dryness and salinity. The objective of this study was investigation effect of different surface gravel cover on runoff and sediment yeild. For this porpose, 36 field plots with 20 meter length and 0.5 meter width at 3 percent slope were construct...

Temporal Variation Pattern of Runoff Generation and Rill Erosion in Different Soils and Slope Gradients

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...

The influence of soil moisture on threshold runoff generation processes in an alpine headwater catchment

This study investigates the role of soil moisture on the threshold runoff response in a small headwater catchment in the Italian Alps that is characterised by steep hillslopes and a distinct riparian zone. This study focuses on: (i) the threshold soil moisture-runoff relationship and the influence of catchment topography on this relation; (ii) the temporal dynamics of soil moisture, streamflow ...

Modeling response of soil erosion and runoff to changes in precipitation and cover

Global climate has changed over the past century. Precipitation amounts and intensities are increasing. In this study we investigated the response of seven soil erosion models to a few basic precipitation and vegetation related parameters using common data from one humid and one semiarid watershed. Perturbations were made to inputs for rainfall intensities and amounts, and to ground surface cov...
