The high hillsides of the Tehran metropolis are prone to landslides due to the climatic conditions and the geological, geomorphologicalcharacteristics of the region. Therefore, it is vitally important that a landslide susceptibility map of the region be prepared. For thispurpose, thematic layers including landslide inventory, lithology, slope, aspect, curvature, distance to stream, distance to ...

Watersheds are changed positively or negatively as biotic and abiotic factors in natural circumstances impact them. Landslides, as a physical factor, one of the negative consequences on these catchments. Masoleh watershed, in North of Iran, is one of the susceptible areas to explode the natural landslides. In other to landslide hazard zonation, the Dempster-Shafer model is which is used has 14 ...

Since direct experimental evidence is not available, this must be verified through a modeling approach, providedadequate data be available. Many statistical methods are used to study the relation between independent anddependent variables.This research was carried out at the western part of Jazmurian basin tlocated in the southeast ofIran. In this paperused ten physical characteristics such as ...

[1] The Kyrgyz Range, located on the northern margin of the western Tian Shan, illustrates long-term (10–10 year) transient landscape evolution in response to an active basement-cored rock uplift. Eastward propagation of range uplift has progressively exposed resistant bedrock capped by a tilted, (formerly) planar, pre-Cenozoic unconformity. We develop an approximate, stream power–based analyti...

Abstract Flood causes great and uncompressible damage to people’s life and properties as well as environment each year in Iran. This research was carried out at the west section of Jazmurian basin that placed in the southeast of Iran. In this research physical characteristics such as area (A), perimeter (Pr), average elevation of basin (av.e), average slope (av.s), gravelious coefficient (G),...

This study investigated the effect of parasite infection with Posthodiplostomum cuticola on fish growth rate in Zaringol Stream in Golestan Province. A total number of 447 fish specimens (173 Capoeta capoeta gracilis, 111 Alburnoides eichwaldii, 131 Paracobitis malapterura, 32 Neogobius fluviatilis) were captured by electrofishing during December 2009 to September 2010. Total number of para...

We have studied the reorganisation of drainage patterns in response to the tectonically driven emergence of a small ridge (South Rough Ridge) along the flank of a larger ridge (Rough Ridge) as described by previous workers in the Central Otago region of New Zealand. We compare the results of a numerical model of landscape evolution (CASCADE) in which stream incision is linearly related to local...

Scaling is an integral component of ecology and earth science. To date, the ability to determine the importance of air – water gas exchange across large spatial scales is hampered partly by our ability to scale the gas transfer velocity and stream hydraulics. Here we report on a metadata analysis of 563 direct gas tracer release experiments that examines scaling laws for the gas transfer veloci...
