In the framework of the application of remote sensing to civil protection from floods, the problem of the detection of flooded areas and ground changes in high-resolution images is addressed in this paper. Specifically, the high-resolution multitemporal observation capability offered by the current COSMO-SkyMed synthetic aperture radar (SAR) constellation is exploited. This work is framed in th...

The theory for non-stationary flow in translatory waves is developed for an inclined plane in a prismatic channel and a funneling channel. The existence of translatory waves traveling over dry land or superimposed on constant flow is established, and the dependance on the initial flow value is discussed. Inherent instabilities of the wave tail are discussed. Data from a CFD simulation of a joku...

INTRODUCTION: In the first half of April 2019, heavy rains in central and western parts of Iran resulted in great floods. The rains affected 24 provinces and caused extensive damage to urban and rural infrastructure. Since Iran, especially the northern, western, and southern provinces of Iran are prone to floods, the floods are expected to occur every year in many provinces. Therefore, the pres...

Flash flooding often leads to extremely dangerous and sometimes catastrophic conditions 9 in rivers due to characteristics such as: short timescales, the limited opportunity for issuing 10 warnings, and the frequent high average mortality. Many past extreme flood events have been 11 accompanied by flash floods, and they have also been one of the main sources of serious loss of 12 human life amo...

Constructing of control structures, like dams, change temporal and spatial unequal distribution of water ,and also play an effective role in reduce or eliminate of damage that caused by floods. So reservoir dam’s effect on floods discharges reduction must be determined. In this study the rain Information and flood hydrographs were used to check the flood routing for previous period of Maroon da...

BACKGROUND Extreme precipitation events are increasing as a result of ongoing global warming, but controversy surrounds the relationship between flooding and mosquito-borne diseases. A common view among the scientific community and public health officers is that heavy rainfalls have a flushing effect on breeding sites, which negatively affects vector populations, thereby diminishing disease tra...
