Flood risk analysis is more complex in urban areas than that in rural areas because of their closely packed buildings, different kinds of land uses, and large number of flood control works and drainage systems. The purpose of this paper is to propose a practical framework for flood risk analysis and benefit assessment of flood control measures in urban areas. Based on the concept of disaster ri...
introduction extreme floods, hyperconcentrated and debris flows are common natural hazards in the basins which located in the northern slops of alborz mountain range (iranian north system). flood occurrence in golestan national park in 2001, 2002 and 2005( hosseinzadeh and jahadi toroghi 2012), yearly flash floods in masuleh catchment( rezaei, 2009), large flood in neka basin in 1999(poorahmad ...
There are many patients with inflammatory acne vulgaris who are not compliant or eligible to consume acne medications, such as oral antibiotics or isotretinoin. PubMed and Medline databases were searched for all related articles. All finding were summarized and chronologically presented in the tables. Nonmedical device-based therapies largely improve the treatment of active inflammatory acne vu...
The most important problem in estimating floods is the lack of sufficient statistics and consequently the lack of evaluation of the appropriate amount of flow. One of the flood estimation methods in these basins is the use of hydrological modeling. In this study, Shahbahram river flood modeling was performed with Nazmkan hydrometric station located in Kohkiluyeh Boyer-Ahmad province with HEC-HM...
the present study has tried to accomplish an analysis of margaret atwood’s novels oryx and crake, and the year of the flood in the light of posthuman and cyborg theories. considering posthumanism as a critical reading of some notions of humanism focus of which in this thesis has been identity, new definitions for humanity and human identity are formed. haraway’s cyborg, as one possible new figu...
Over the last decade, neural networks-based flood forecast systems have been increasingly used in hydrological studies. Usually, input data of the network are composed by past measurements of flows and rainfalls, without providing a description of the saturation state of the basin, which in contrast plays a key role in the rainfall-runoff process. Here, we adopt a fuzzy approach in order to pro...
Iran is located in dry zone of mid-latitude in which the mean rainfall is 250 mm and it has dramatic tempo-spatial changes. Rainfalls with short persistency are of characteristics of dry regions and it is also tangible in Iran. However, Iran’s rainfalls persistency ranges from 1 to 45 days and have dramatic tempo-spatial changes, but the maximum amount and days of rainfalls are supplied by rain...
South Asian countries are the lands of great topographic and climatic contrasts. Floods, cyclones, earthquakes, droughts and heavy rainfalls are some major natural threats that this region faces. The tsunami of December 26, 2004 that stuck the coasts of most landmasses bordering the Indian Ocean killed more than 225,000 and many more became homeless in eleven countries of Asia. This was followe...
Abstract Coupled 1D–2D hydrodynamic models are widely utilized in flood hazard mapping. Previous studies adopted conceptual hydrological or 1D to evaluate the impact of drainage density on river flow. However, affects not only flow, but also flooded area and location. Therefore, this work adopts model SOBEK investigate The uncertainty mapping is assessed by a designed case real case, Yanshuixi ...
