Maps shading terrain as if illuminated by a point light source (i.e. hill-shading) are commonly used in cartographic displays. These hill-shaded maps are especially important for representing mountainous areas, due to the rapid variations in the orientation of terrain elements. Although these hill-shaded maps reveal the coarser landforms and the finer texture of the terrain, they can be enhance...

The most crucial but difficult task in the analysis of the risk due to landslide hazard is the estimation of the conditional probability of the occurrence of future landslides in a study area within a specific time period given the presence of spatial and geomorphologic features. This contribution explores a modeling procedure for estimating that conditional probability. The procedure proposed ...

condition of contour lines in topographic maps, explains more geomorphologic issues such as effective processes in the land forms found in nature. change in the curvature of the transverse profile of a valley in mountainous areas, the peak of the mountain range, also reflect the geomorphologic features and expresses the tectonic events and climate changes occurring in the region. these changes ...

Altogether 327 valleys and their 314 cross-sectional profiles were analyzed on Mars, including width, depth, length, eroded volume, drainage and spatial density, as well as the network structure. According to this systematic analysis, five possible drainage network types were identified such as (a) small valleys, (b) integrated small valleys, (c) individual, medium-sized valleys, (d) unconfined...

this study aims to investigate the semantic and syntactic features of verbs used in the introduction section of applied linguistics research articles published in iranian and international journals. a corpus of 20 research article introductions (10 from each journal) was used. the corpus was analysed for the syntactic features (tense, aspect and voice) and semantic meaning of verbs. the finding...
