The RAP is a NP-hard problem and different methods, mostly heuristics, are available to solve it

In this study, the changes in the properties of four different pedons classified as Lithic Leptosol (Lithic Xerorthent, LPq), Dystric Cambisol (Typic Dystroxerept, CMd) and Haplic Cambisol (Typic Haploxerept, CMha) located on three adjacent land use types which are native forest, pasture and cultivated fields include some extracellular enzymes, organic matter, pH, EC, CaCO 3 , bulk density, total porosity, hydraulic conductivity and aggregate stability. The effects of agricultural practices on soil properties taken from each four adjacent land use types were most clearly detected in the past 50 years with the land use change. Land use change and subsequent tillage practices resulted in significant decreases in organic matter, total porosity, total nitrogen a...

The proposed algorithm enhances the precision of the GA solutions by introducing a Gaussian perturbation to the decoding function. This non-deterministic decoding enables individuals to represent any point in the continuum instead of finite discrete points. As the generations evolve, information gathered from the most fit members is continuously

The study area is located about 44 km north of Ankara and covers 17.5 km2. The selected theme layers of this model include topographic factor, soil factors (depth, texture, impermeable horizon) and land use. Slope layer and land use-land cover data were prepared by using DEM and Landsat-TM satellite image. According to land use classification, the most common land use type and land cover are rangeland (50.5%) then, rainfed (36.4%), week forest land (3.2%), irrigated land (0.7%) and other various lands (rock out crop and lake) (9.2%). Each land characteristic is also considered as a thematic layer in geographical information systems (GIS) process. After combination of the layers, soil erosion risk map was produced. The results showed that 44.4% of the study area is at high soil erosion risk, whereas 42% of the study area is insignificantly and slightly...
