Tectonic processes are major factors controlling landform development in tectonically active areas. In order to evaluate quantitative measurement of tectonic activities in the Alamarvdasht basin in the south of Iran, six different morphological indices including stream-gradient index (SL), drainage basin asymmetry (Af), hypsometric integral (Hi), valley floor width-valley height ratio (Vf), dra...

the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...

Aims and Backgrounds: Almost no area in the world can be found that has not been affected by tectonic processes. The morpho-tectonic indices of the basin are used to investigate the active tectonics. Morphometry can be defined as the quantitative measurement of the shape of the Earth's landscape that using these quantitative measurements can identify areas with active tectonics. The purpose o...

the present study carried out to identify neo tectonic activity of the gorgan river basin in golestan province, in north of eastern alborz range is investigated by four geomorphic indices including the stream– gradient index (sl), drainage basin asymmetry (af), reveres symmetry of topography (t) and mountain front sinuosity (smf). result from the analysis is accumulated and expressed as an in...

study of tectonic affects in many fluvial systems shows that, rivers are valuable tools to active tectonics surveying. study of stream channels and their associated deposits offset by faulting may reveal the amount displacement at particular site and give information that is critical for future earthquake hazards evaluation. study area which is a subbasin of atrak river is located at the ne ira...

introduction  Active tectonic studies are one of the most important topics in earth science and their results are widely used for assessing natural hazards and land use development and management plans in populated areas (Pedra et al., 2009, 220).Among these, geomorphic indices have been effective in assessing active teconic in large areas due to their high speed and accuracy (Clare & Pinter, ...

current research in order to identify neo tectonic activity of the ziyarat basin has been made on the northern slopes of the eastern alborz in south-gorgan and using the index of morpho tectonic and tectonic evidence in the area. in this regard, the 6 morphological parameters were calculated and the results are analyzed. the overall results of these features, as indicators of the relative activ...

this thesis aims at putting together two of the vestest areas of study there is in humanities: bioethics and literature. the two novels in question, oryx and crake and the year of the flood, are considered as some of the most succssful examples of spculative fiction. in these novels the biological and environmental issues raised as looked at from a bioethics point of view.

Iran is well known for having countless historical and instrumental records of tectonic events. Shahriary catchment, as a study area, is part of the Zagros collision seismic province. This research aimed to introduce a new method which is useful in identifying the relative active tectonic events of an area. The research method was designed in order to calculate the relative active tectonic inde...
