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...

A variety of predictive models is currently used to map the spatial distribution of earth surface processes and landforms. In this study, we tested statistical consensus methods in order to improve the predictive accuracy of geomorphological models. The distributions of 12 geomorphological formations were recorded at a resolution of 25ha in a sub-arctic landscape in northern Finland. Nine envir...

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...

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...

Identifying a good site for groundwater exploration in hard rock terrain is a challenging task. In hard rocks, groundwater occurs in secondary porosity developed due to weathering, fracturing, faulting, etc., which is highly variable and varies sharply within very short distances, contributing to near-surface inhomogeneity. In such situations topographic, hydrogeological and geomorphological fe...

the study area, paykola anticline, is located in the southwestern part of kermanshah province. the aim of this research is to evaluate the geomorphological indexes of active tectonics in paykola anticline as well as to study the effect of tectonic in the form and direction of geomorphological landforms. to achieve the aim of study, the lithological and tectonic characteristics of study area wer...

of geomorphological investigation. However, the process of this analysis itself is in fact still unclear, even though geomorphologists use it very often. Therefore, a firm concept of geomorphological analysis has been postulated according to a proposal published by Urbánek (2000a, b) and applied to geomorphological research of previously glaciated areas in the Šumava Mts. (the Czech Republic). ...

Definition Geomorphology is the science that studies the origin and development of landforms and how those landforms combine to form landscapes. Landforms are shaped by geomorphological processes, many of which involve the weathering, erosion, transportation, and deposition of surface materials (rock, sediment) by gravity, ice, wind, or water. Both erosional and depositional landforms can be id...

  The natural environment has performed as determinative factor for vitality of the human habitations since the dawn of era, like habitations’ places and other human foundations which have been absolutely influenced by natural factors particularly geomorphological and geological factors. Geomorphological studies will evaluate environmental conditions of the chronological settlement ...
