In this research, due to the abundance of tectonic and karstic structures in the Prav Bisotun region, the relation between fault building and karstic springs was evaluated. To do this, we first prepare information layers including the location of the springs, the location of the closed holes, faults, the slope and the elevation floor layer, and then the graph of the grains of the faults is draw...

Given the ancient history of the Kurdish region in western Iran, its seemingly simple architecture has not been thoroughly investigated.  This research is an attempt to identify and characterize vernacular housing in western Kurdistan. The main aim of the research is to recognize the elements and concepts of these typologies, as well as the application of these concepts, and to inspire contempo...

EXTENDED ABSTRACT      The land use change of watersheds has entailed many impacts on the processes of erosion and sediment yield over the time, and has caused the loss of soil quality and fertility. On the other hand, an increase in the sediment generation and its accumulation would reduce the capacity of the reservoirs. In this respect, the purpose of this study was to evaluate the effects o...

  1-Introduction   The Zagros Mountains range with a northwest-southeast direction covers a large part of western Iran. This range acts as a barrier against mid-latitude westerly airflows and thereby generates significant orographic rainfalls, resulting in a hospitable environment which has been home to ancient civilizations. Major variations in the westerlies can lead to significant environ...
