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...
Erosion processes and their impact are driven by a multitude of biophysical factors that are poorly understood in the Andean highlands. The first attempt to assess soil erosion rates in Peru was made by Felipe-Morales et al. (1977) using runoff plots. Since then, very few erosion investigations have followed and reference to Andean soil erosion is often criticized because of the lack of quantit...
Soil conservation and control of erosion is a basic problem in all countries. The goal of this research is to estimate erosion and sediment yield in Ekbatan Dam drainage basin by Erosion Potential Method (EPM), using Geographic Information System (GIS). The basin is located in Hamedan Province, west of Iran, in a cold and semi- arid region, with an average annual rainfall of 334mm. The study ar...
BACKGROUND AND STUDY AIMS The clinical utility of computed virtual chromoendoscopy with flexible spectral imaging color enhancement (FICE) in capsule endoscopy (CE) remains controversial. To clarify the clinical utility of FICE-enhanced CE in evaluating small bowel lesions, we quantitatively assessed white light (WL), FICE, and blue mode (BM) images and examined the sensitivity of these 3 imagi...
Erosion and sediment in a basin can be estimated by calculating forecasting using various methods. This study aims to assess erosion sedimentation the Krueng Jreu sub-basin province of Aceh, Indonesia, Gavrilović method. research was carried out analyzing secondary data for last ten years, from 2012 2021. Data include geology, slope, land use, river channel networks. The observed parameters coe...
Extended abstract 1- Introduction The degradation of natural resources in recent decades has led to increasing the erosion and an increase in the sediment production rates. Many activities are carried out at watershed level in order to control the destruction and decrease its effects. Assessment of watershed management projects is one of the most important issues performed today of implementa...
different types of soil erosion including gully erosion occur in many parts of iran. the west of iran is further threatened by gully erosion due to its specific physical and climatic conditions. however, few studies have been carried out to study the sediment production of gully erosion in iran. this research was therefore conducted to measure storm-wise sediment production of gully erosion in ...
1 Abstract We present results of self-consistent experiments of basin formation by extension and basin inversion through subsequent contraction. Our viscous-plastic finite element models include feedback interactions between crustal deformation, the development of local shear zones, and sedimentation and erosion. The extensional basins show a high degree of sensitivity to crustal strain softeni...
Splash erosion is recognized as the first stage in the process of erosion that results in bombardment of the soil's surface with rain drops. Two basic processes in soil erosion are the dispersion of soil particles by rain drops and the changes caused to the soil's structure, which are then moved by runoff. In this research, the effect of various rainfall intensity (60, 90 and 120 mm/hr) on the ...
