Physical modelling optimization of a filter check dam in Switzerland
After a major flood with a peak discharge of 177 m3/s in the city of Martigny (Valais, Switzerland) by the alpine river Drance in October 2000, the local authorities are strengthening efforts for the protection of the urban area. The Drance has an annual average discharge of 10 m3/s and the most important floods occur in the late summer. Two lateral torrents potentially supply the Drance with d...
متن کاملInvestigating the vulnerability downstream area of Taleghan dam due to dam failure
Due to the immense damage caused by dam failure, especially dams constructed near large cities, it is necessary to consider the breaking phenomena as well as studying and designing different parts of the dam. For this purpose, the hydrograph of the outflow due to dam failure must be identified according to size of the fracture and then flood routing, and flood zone must be determined based on t...
متن کاملbore propagation due to sudden dam failure
the problem of creation and subsequent propagation of bore has been examined and studied by a number of investigators who they were interested in unsteady flow problems for which sudden changes in either flow or depth or both occur. in this paper, the shock conditions and the method of characteristics for predicting the downstream flooding produced by a dam failure. in the dam-break problem whe...
متن کاملHow to Check Urinary Incontinence
دیواره مثانه شامل شبکه انبوهی از فیبرهای عضلانی صاف می باشد که از افزایش ناگهانی فشار مثانه که منجر به انقباض و نشت ادرار از مثانه قبل از پرشدن کامل آن می شود جلوگیری می کند و حدود ۵۰۰ سی سی ادرار را در خود جای می دهد. مجرای پیشابراه که بعنوان محل خروجی برای مثانه محسوب می شود شامل دو لایه عضله صاف و یک ناحیه تنگ شده عضلانی است که تحت کنترل ارادی می باشد و بعنوان اسفنکتر خارجی عمل می کند. هنگام...
متن کاملPoroelastic loading of an aquifer due to upstream dam releases.
Short-term changes in the hydraulic head of surface water bodies are known to influence the shallow response of hydraulically connected groundwaters. Associated with these fluctuations is the physical increase in stream water creating a mechanical load on the ground surface. This load is supported by the geologic materials (sediment or rock) and the pore fluid contained within the pores. Change...
