the main objective of this study was to arak city zoning geomorphological parameters of the model using fuzzy logic. in order to realize these objectives, 10 parameters including of height, distance from fault, distance from the main channel, distance from sub-channel, distance from road, slope percent, distance from settlements, terrain type, erosion potential and seismic vulnerability in the ...

The increasing frequency and/or severity of extreme climate events are becoming increasingly apparent over multidecadal timescales at the global scale, albeit with relatively low scientific confidence. At the regional scale, scientific confidence in the future trends of extreme event likelihood is stronger, although the trends are spatially variable. Confidence in these extreme climate risks is...

This work performs a geomorphological mapping procedure applied to the evolutionary analysis of the landscape, such that it groups different geomorphological units photointerpreted in large geomorphological domains. This allows greater utility and ease of identification and application in the different multidisciplinary studies of environmental geology and the evolution of the landscape. Geomor...

Liechtenstein has faced an increasing number of natural hazards over recent decades: debris flows, slides, snow avalanches and floods repeatedly endanger the local infrastructure. Geomorphological field mapping and geoelectrical profiling was used to assess hazards near Malbun, a village potentially endangered by landslides, and especially debris flows. The area is located on the tectonic conta...

The ARC/INFO 6.1 Grid system was applied in the 170 km large Henley Dam and the 19.4 km large Cedara basins, KwaZulu Natal, South Africa, to determine hydrological and geomorphological parameters required to simulate water quantity and water. A sensitivity analysis was carried out to evaluate the effects of the grid mesh size on basin slope by producing a number of grids with grid mesh sizes ra...

in recent years, the occurrence of water and wind erosion indifferent parts of country due to the changes of land use from the forest andpasture into the agricultural and also construction of communication lineshave increased. the study and research on this phenomenon, the effectivefactors in creating them and also identification of geomorphology faciestypes are necessary to prevent the waste o...
