abstract the purpose of this paper is to inform students and researchers of geomorphology from the situation of this science at present and in future, in iran, after the islamic revolution. to fulfill this purpose and to prouide full information about the situation of geomorphology in iran, various areas of this science are presented chronologically at the begining of the article. the findings ...

Studying the variations of energy balance and surface temperature, vegetation and spectral reflectance of geomorphological features during the catastrophic processes such as storms and environmental hazards on a large scale requires powerful tools such as thermal remote sensing. This research has considered the effective use of remote sensing methods by such practical approach. The study area i...

Theoretical assumptions, research methodologies and results applications of innovative geological and geomorphological mapping for landslide hazard evaluation in the alpine environment are presented in the paper. Case studies from the Italian NW-Alps highlight the role of Geomatics techniques in enhancing the accuracy of multitemporal reconstructions of geomorphic processes and landforms. Aeria...

Methods Maximum parsimony analysis was used to assess phylogenetic relationships among living large-bodied hominoids (= humans, chimpanzees, bonobos, gorillas, orangutans), and various related African, Asian and European ape fossils. Biogeographical characteristics were analysed for vicariant replacement, main massings and nodes. A geomorphological correlation was identified for a clade we refe...

This study is based on a data set of aftershocks (location, fault−plane solutions) following the M=5.1 Arudy earthquake (02/29/80, French Western Pyrenees), and complementary geomorphological data (virtual geology using DEM and aerial photography). Data processing using Geophysical Information System are combined with identification of multi−structures based on the anisotropic wavelet formalism...

An acceleration algorithm for spectral unmixing approach is proposed based on subset selection. The method classifies the pixels in a spectral image into accurate and approximated unmixing groups based on the similarity and dissimilarity of geomorphological features in neighboring areas. Real spectral images are used for unmixing benchmark tests for accuracy and performance verification. The re...

This paper follows a geostatistical approach for the evaluation, modelling and visualization of the possible local interactions between natural components and built-up elements in seismic risk analysis. This method, applied to old town centre of Potenza hilltop town, offers a new point of view for civil protection planning using kernel density and autocorrelation indexes maps to analyse macrose...

The “laguna de El Conde” wetland Ramsar reserve (Córdoba, Spain) depicts a geomorphological progression with different Pleistocene and Holocene stages and reaching a concluding situation by anthropic manipulation of the local network of tributaries. The nature of the sediments carried into the Triassic-gypsum depression where the reserve is situated. Further, dissolution processes and the forma...
