In Brazil, research related to the occurrence and prevention of debris flows is incipient when compared extent impacts caused by phenomena. There a need for further studies that consider susceptibility hazard, especially in areas are environmentally socioeconomically vulnerable. This study aimed at assessing debris-flow hazard Rio das Pedras watershed, Cubatão (State São Paulo, Brazil), based o...

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 ...

The Karnafully is one of the most important rivers due to its profound influence on water chemistry and sediment characteristics. The present study intended to assess the quality of water and sediment from intertidal zone of this river in respect to the pollution index. Seasonal water and sediment samples were collected during four seasons (Monsoon, post-monsoon, winter, and pre-monsoon) of 201...

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...

Title: Development and evaluation of a multi-dimensional spatially and temporally dynamic mesohabitat classification model for stream management and water flow allocation planning in southern New England streams Project Number: 2006CT123B Start Date: 5/1/2006 End Date: 5/1/2008 Funding Source: 104B Congressional District: 2 Research Category: Biological Sciences Focus Category: Ecology, Geomorp...

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...
