Once segmentation of 3D surface data of a rock pile has been performed, the next task is to determine the visibility of the surface rocks. A region boundary-following algorithm that accommodates irregularly spaced 3D coordinate data is presented for determining this visibility. We examine 3D surface segmentations of laboratory rock piles and determine which regions in the segmentation correspon...

The risk of potential water erosion is computed on a raster cell basis using elevation and soil data which are expressed by two factors soil erodibility and slope steepness. The SIte COmparative Method (SICOM) is used to evaluate the heterogeneity of these factors inside the borders of field blocks. With the help of this approved method a set of indicators are provided to support the evaluation...

The erodibility and erosion resistance of Quaternary sediments play a pivotal role in both the hydrologic processes soil cut slopes. To investigate runoff sediment yield slopes along Pai-Mo road, we performed indoor simulated rainfall experiments under 50° steep slope high intensity (120 mm/h), based on area’s climatic characteristics properties. included various rock fragment contents (30%, 40...

investigation of desertification trend needs understanding of phenomena creating changes singly or action and reaction together in the manner that these changes were ended up in land degradation. in investigation of pedological criterion onland degradation in quaternary rock units, first, a part of the rude-shoor watershed area was selected. after distinguishing target area, maps of slope class...

generally, the evaluation and assessment critical condition of rill formation are useful for a better understanding of soil erosion processes. the inherence characteristics of soils, which have much dynamic variations on the hill-slopes and are affected by rill formation, are the soil critical shear stress and soil erodibility factors. this study aims to assess experimental rill incision thresh...
