BACKGROUND In the past 10 years, 13 fatal earthquakes have occurred in Iran and led to death of 30,000 people whom most of them were killed in the earlier hours of the disaster. Disaster Medical Assistance Teams are groups of trained medical and non-medical personnel with various combinations that on the optimal conditions are deployed just within 8 hours of notification and are able to work se...
The occurrence trend of floods in recent years shows that the most of Iran regions located in attacks of destructive floods and loss of life and property of flood damages is increasing. Watershed management practices (WMPs) are one of the superior and appropriate solutions for flood hazards mitigation. The impact of WMPs can be investigated using different approaches. In this study, the direct ...
Flood spreading is among preventing method from damage of deluge, especially perishing of water and soil in latrine basins of arid and semiarid regions. Accumulation of sediments on the flood spreads regions lead to changes in soil fertility, revival and support of plant covering and controlling of desertification and change in physicochemical properties of soil in these regions. In order to me...
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...
هدف از اجرای این طرح بررسی محیط زمین شناسی شهر زاهدان و تعین زمین شناسی زیست محیطی شهر جهت رفع مشکلات مربوط به بلایای طبیعی و الودگی ها می باشد.
In the present study, the impact of watershed management practices on flood hydrograph characteristics was investigated using HEC-HMS model. In order to design, calibrate, and validate the model, data from a representative paired watershed (Kakhk Watershed, Khorasan Razavi Province, Iran) was collected and field surveys were performed to have the dataset further completed. Results of paired sam...
flood routing has many applications in engineering projects and helps designers in understanding the flood flow characteristics in river flows. floods are taken unsteady flows that vary by time and location. equations governing unsteady flows in waterways are continuity and momentum equations which in case of one-dimensional flow the saint-venant hypothesis is considered. dynamic wave model as ...
Overtopping is one of the main factors responsible for dam failure. To avoid overtopping, dam is equipped with one or some spillways to release the water impounded in the reservoir. The number and size of these spillways are determined on the basis of design flood. Determination of design flood of dam spillway can be formulated as a multiobjective risk problem. This problem can be solved by Qua...
