The dangers of torrents and floods that taken place repeatedly in many countries of the world, Saudi Arabia is one of them, are impossible to be fully prevented or controlled. But it is possible to limit its effects and minimize its losses. That's by defining the endangered places and sitting suitable maps for them as well as conducting researches and studies that enhance the real-time flash fl...

BACKGROUND Stroke may lead to several health problems, but positive effects can be promoted by learning to perform physical therapy techniques correctly. OBJECTIVE To compare two different types of observational practice (video instructions and demonstration by a physical therapist) during the use of incentive spirometry (IS). METHOD A total of 20 patients with diagnosis of stroke and 20 he...

The hydrological modeling has become an intensively studied subject in recent years. One of the most significant problems concerning this issue is to provide the mathematical and statistical tools, which allow to forecast extreme hydrological events, such as severe sea or river floodings. The extreme events on water have huge social and economic impact on the affected areas. Due to these reason...

Flash floods are considered to be one the worst kind of hazard. They are characterized by their suddenness, rarity, small scale, heavy rain and peak discharge, unpredictable, fast and violent movement. It has severe effects on human society in the form life losses, damages to property, roads, communication and on natural settings. Advances in hydrology, meteorology, engineering, using of GIS an...

Understanding pathways of risk following a natural disaster may help create next-generation targeted interventions. The current study examined if a biomarker of cognitive-affective response (pupil dilation) could identify which individuals are at greatest risk for depression following disaster-related stress. Fifty-one women completed a computer-based task assessing pupillary response to facial...

In view of the abnormal phenomenon that a flood peak increased in August 2004 , July 2005 and August 2006 along the lower Yellow River, the experiments of this abnormal phenomenon is studied. It is found that the flood increase was due to the decrease the channel roughness in the propagation of high concentrated flood carrying the extra fine sediment which was discharged from xiaolangdi reservo...

introduction: the greatest part of constructed dams belongs to embankment dams and there are many examples of their failures throughout history. about one-third of the world’s dam failures have been caused by flood overtopping, which indicates that flood overtopping is an important factor affecting reservoir projects’ safety. moreover, because of a poor understanding of the randomness of floods...
