Soil erosion is a serious worldwide environmental problem that stems from a combination of several factors such as agricultural intensification, deforestation, increasing population, and rainstorms. This phenomenon produces a soil fertility decline, removes soil rich in nutrients and increases natural level of sedimentation in the rivers and reservoirs reducing their storage capacity as well as...

Erosion potential was estimated for road approaches during 4 phases of a timber harvesting scheduled for 23 stream crossings in the Virginia Piedmont. The objectives of this study were to: (1) examine four different types of stream crossing structures (steel bridges, pole bridges, standard culverts, and reenforced fords) in order to determine if the type of stream crossing affects erosion poten...

One of the most common approaches to modelling soil erosion worldwide has been implementation original Universal Soil Loss Equation (USLE) and its revised version, RUSLE. However, despite widespread use, often there are discrepancies in methods used compute it values elicited for five individual factors that comprise this function. Such pitfalls subsequently skew final results obtained many stu...

This work describes a genetic programming (GP) approach that creates vegetation indices (VI’s) to automatically detect the sum of healthy, dry, and dead vegetation. Nowadays, it is acknowledged that VI’s are the most popular method for extracting vegetation information from satellite imagery. In particular, erosion models like the “Revised Universal Soil Loss Equation” (RUSLE) can use VI’s as i...

In many watersheds, water quality is degraded by nutrients and sediment from row crop agriculture. The continued development of watershed process models on one hand and optimization tools on the other hand places today's decision-makers in a position where the problems of cost-effective assignment of conservation activities can be solved for a variety of landscapes and environmental objectives....

Fluvial processes and channel development on landscapes have recently received more attention as designers attempt to establish or replace natural streams on disturbed or degraded sites. Several approaches using similar parameters have been developed to evaluate stream development and erosion processes on natural soils and landscapes. Such approaches include the Manning’s and stream power equat...

Soil erosion is a most severe environmental problem in hilly area. The study carried out on Upper Bagmati River basin, North of Kathmandu valley having an area 61 Sq.km. (approx). Universal Loss Equation (USLE) model, with Geographic Information System (GIS) has been used to quantify the soil loss. Erosion modelling requires huge amount information and data, usually coming from different source...

Water erosion is a natural fact in the cycle of shaping earth’s landforms and most evident form of land degradation on a planetary scale (Roose & De Noni, 2004; Dautrebande Sohier, 2006; Toumi et al., 2013; Azaiez, 2020a). Its effects have largely affected rural landscape. Although it result of an ancient primeval climatic tectonic forcing, man’s footprint its intensification remains reali...
