The frequency of summer flood events has strongly increased in Eastern Europe during the last decades. The creation of water storage areas to avoid flooding is often combined with the recreation of more natural and biodiverse riverine systems. This urges the need to understand the consequences of summer inundation, when microbial activity is significantly higher than during winter inundation, f...
The new mathematical model for tsunami evolution by Tobias & Stiassnie (Tobias & Stiassnie 2011 J. Geophys. Res. Oceans 116, C06026) is used to derive a synthetic tsunami database for the southern part of the Eastern Mediterranean coast. Information about coastal tsunami amplitudes, half-periods, currents and inundation levels is presented.
Floodplain forests, namely the Várzea and Igapó, cover an area of more than 97 000 km2. A key factor for their function and diversity is annual flooding. Increasing air temperature and higher precipitation variability caused by climate change are expected to shift the flooding regime during this century, and thereby impact floodplain ecosystems, their biodiversity and riverine ecosystem service...
Environment determines the distribution of mosquito-borne diseases in that it influences the vector-host-pathogen transmission cycle, including vector distribution, abundance and diversity. In this study, we analyse the relationship between environmental variables estimated by remote sensing and the spatial distribution (presence, abundance and diversity) of seven mosquito species vectors of We...
The U.S. Geological Survey is developing new Landsat science products. One, named Dynamic Surface Water Extent (DSWE), is focused on the representation of ground surface inundation as detected in cloud-/shadow-/snow-free pixels for scenes collected over the U.S. and its territories. Characterization of DSWE uncertainty to facilitate its appropriate use in science and resource management is a pr...
(2015) An urgent case for higher resolution digital elevation models in the world's poorest and most vulnerable countries. Front. Earth Sci. 3:50. Natural disasters disproportionately impact the poorest countries; low-income developing countries accounted for 95% of all disaster fatalities between 1970 and 2008 (Handmer et al., 2012). These impacts are generally expected to worsen as the climat...
Because of urban rapid growth of Iran, some problems such as propagation of environmental pollutions, urban inundation and flood hazards due to lack of appropriate drainage systems and irregularity of conduits & streams are the major difficulties in urban watersheds. Because of hydrological & hydraulic processes complexities in urban area, using of computer models would be effective. In this st...
