The results of investigations on shaping the soil moisture ratio in mountain basin Mątny stream located Gorce region, Poland, are presented. A was defined as a given point to one base watershed. Investigations were carried out, using TDR device, for 379 measuring points an irregular network, 0–25 cm layer. Values fluctuated between 0.75 and 1.85. Based measurements, artificial neural network (A...

Shuangbai County, located in Yunnan Province, Southwest China, possesses a complex and diverse geological environment experiences frequent landslide disasters. As significant area for disaster prevention control, it is crucial to assess the susceptibility of landslides effective prevention, urban planning, development. This research focuses on eleven influencing factors, including elevation, sl...

In this paper, effects of the cross shore and groyne wall slopes on flow parameters around an impermeable groyne were considered using a three-dimensional numerical CFD model (i.e., FLUENT). The k-ε turbulence model was used to evaluate the Reynolds stresses. The model was first applied to a vertical groyne on a flat bed and the model results were compared with the relevant experimental data. T...

introduction: spatial variation of soil properties is significantly influenced by numerous environmental factors such as landscape features, including position, topography, slope gradient and aspect, parent material, climate and vegetation. soil properties vary spatially in south- and north-facing hill slopes. this factor (different slope aspects) can affect the distribution of soil organic mat...

A stereo vision based terrain traversability estimation method for offroad mobile robots is presented. The method models surrounding terrain using either sloped planes or a digital elevation model, based on the availability of suitable input data. This combination of two surface modeling techniques increases range and information content of the resulting terrain map.

Digital elevation models (DEMs) cover a wide range of scales, and allow statisticalanalysis of geomorphometric parameters. At global or continental scale, DEMs covering rectangular quadrangles can be considered random samples. Average quadrangle values can be compared at different DEM scales, and for different physiographic provinces. Three independent variables provide valuable descriptions of...

Hydrodynamic pressure is often a crucial factor in the evaluation of slope stability analysis, especially for many rainfall-triggered landslides. Nevertheless, hydrodynamic rarely considered traditional limit equilibrium slice method analysis since effective and reliable data are lacking practice. Moreover, efficient methods to involve these an urgent need. To overcome concerns, flow velocity d...
