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 agricultural landscapes, factors affecting V under steady-state conditions of infiltration are well docuVarious interactions, particularly those existing between the rainmented (Kinnell, 2000). The effect of slope angle on fall intensity, the slope gradient, the slope length, and the tillage runoff for interrill erosion has also been fully investisupposedly can affect the runoff features for...

Land application of organic wastes such as animal manure, municipal wastes, and sewage sludge could alter the soil physical properties. Repeated substantial applications of waste increase the soil organic matter percentage. The available data on effects of waste applications on soil physical properties such as bulk density, water holding capacity at both field capacity and wilting point, and sa...

introduction rainfall erosivity, the propulsion or power of causing erosion in separation and transport of soil particles, is in relation to water erosion. rainfall erosion is causing loss of soil, damage to agriculture and infrastructures which is followed by water pollution. changes in rainfall patterns exacerbate risk of erosion globally. rainfall erosivity plays an effective role in soil er...

The aim of this work was to test a modified version of the Universal Soil Loss Equation (USLE) for assessing the risks of erosion in N. Chalkidiki, Greece. USLE estimates the severity of erosion, thus assisting the decision process in selecting erosion control measures. Although USLE has several limitations, it was selected because it is the simplest approach while remaining robust, and it part...

Expert judgements are potentially a valuable source of information in land degradation assessment, especially in areas where data paucity impedes the use of quantitative models. However, expert opinions are also much disputed because they are not tested for consistency, abstain from formal documentation, while their quantitative interpretation is inherently unidentifiable. This paper evaluates ...
