The Yesa reservoir, the largest Pyrenean reservoir, was constructed in 1959 to supply water to new irrigated areas in the Ebro Depression, NE Spain. It is filled from October to May-June and then releases large quantities of water in the summer via the Bardenas Canal. The results confirm that the frequency of floods downstream of the dam decreased. The reduction mainly depends on two factors: i...

Like many organisms, individuals of the freshwater ostracod species Eucypris virens exhibit either obligate sexual or asexual reproductive modes. Both types of individual routinely co-occur, including in the same temporary freshwater pond (their natural habitat in which they undergo seasonal diapause). Given the well-known two-fold cost of sex, this begs the question of how sexually reproducing...

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 ...

Both human activities and climate change have changed landscapes significantly, especially in coastal areas. Sea level rise land subsidence foster tidal floods permanent inundations, thus changing limiting use. Though many countries, including Indonesia, are aware of these phenomena, the legal status this permanently inundated remains unclear. Indonesia refers to legally as obliterated land. Th...

The historical floods that have occurred since the seventeenth century were collected for a study area in southern Italy. Damages caused by floods, rainfall and the main anthropogenic modifications are discussed all together. The aim was to assess whether the frequency of floods is changing and, if so, whether these changes can be attributed to either rainfall and/or anthropogenic modifications...

In 1990-1996, we evaluated the relative importance of the Amazonian fly (Metagonystilum minense) and the wasp (Cotesiaflavipes), in sugarcane crops, in Central Venezuela. We observed a significant decrease in relative abundance of Diatraea spp. when the Amazon fly abundance increased but not with the wasp abundance. Diatraea spp. abundance in presence of both parasitoids was similar to its abun...

Surveys of the physical aspects of landfalling tropical cyclones are important for at least three reasons: (a) to test the veracity of numerical surge models by comparison with topographically surveyed debris lines that mark the level of marine inundation, along with records from tide gauges; (b)to determine the relative contributions of surge, tide, wave action and wave run-up to the total mar...

Determining the role of different precipitation periods for peak discharge generation is crucial for both projecting future changes in flood probability and for shortand medium-range flood forecasting. In this study, catchmentaveraged daily precipitation time series are analyzed prior to annual peak discharge events (floods) in Switzerland. The high number of floods considered – more than 4000 ...

The objective of this research is to explore the temporal importance community-scale human activity features for rapid assessment flood impacts. Ultimate impact data, such as inundation maps and insurance claims, becomes available only weeks months after floods have receded. Crisis response managers, however, need near-real-time data prioritize emergency response. This time lag creates a assess...
