Landslide and evaluation of geology effective factors on its(Case study: watershed of Garmsar Rammeh)
|Location||21th symposium on geosciences|
|Holding Date||21 May 2008|
Watershed of Rammeh is located in North West Semnan (88 kilometers) and north east Garmsar (48 kilometers) between 52, 37_52, 48 longitude and 35, 21_35, 32 latitude.
Rammeh is contain north east south west trend and of lower to upper, lower chahar tagh, upper chahar tagh, lower Rammeh, upper Rammeh and cold climatic.
Geology (stratigraphy) of Rammeh is Karaj formation, Qom formation, evaporate units of Eocene-Oligocene on the Cenozoic age and there is gap on the Precambrian, Paleozoic, Mesozoic ages. This research is contain landslide study and effective factors based on geology in the watersheds of Rammeh geology factors is contain stratigraphy earthquake, seismotectonic, faults, folds, disconformities etc. Factors were been study by quality and quantity and results presented the crust earth in instability.
Keywords: Landslide, landslide evaluation, geology factors, Garmsar Rammeh.
