We present a decision support system for flood early warning and disaster management. It includes the models for datadriven meteorological predictions, for simulation of atmospheric pressure, wind, long sea waves and seiches; a module for optimization of flood barrier gates operation; models for stability assessment of levees and embankments, for simulation of city inundation dynamics and citiz...

Between summer 1987 and winter 1988 coastal water levels and marsh inundat~on regimes in the Mississippi h v e r Deltaic Plaln of Louis~ana (USA) were anomalously low This penod of low water levels colresponded with the 1987-88 La Nina event, and we hypothesized that the low estuanne water levels were a local manifestation of large-scale cl~matological forcing related to thls unusual event We u...

The mangrove environment is not globally homogeneous, but involves many environmental gradients to which mangrove species must adapt and overcome to maintain the familiar structure and physiognomy associated with the mangrove ecosystem. The stature of mangroves, measured by tree height, decreases along the following environmental gradients from low to high salinity, low to high wind speed, high...

[1] The processes that determine which areas are strong sources of mineral aerosols are not well known. In this study we consider the role of ephemeral lakes in modulating emissions of atmospheric mineral aerosols. We focus on two ephemeral lake regions that have been identified as source regions: the zone of Chotts in Tunisia and Algeria, and Etosha Pan in Namibia. Comparisons of satellite ret...

An efficient flood alarm system may significantly improve public safety and mitigate damages caused by inundation. Flood forecasting is undoubtedly a challenging field of operational hydrology and a huge literature has been developed over the years. In this paper, we first define ordered ideal intuitionistic fuzzy sets and establish some results on them. Then, we define similarity measures betw...

New methods allow the direct computation of flood inundation maps from lidar data, independently discharge estimates, hydraulic analysis, or defined cross sections. One method projects interpolated profile measured levels onto surrounding topography, creating a smooth surface that is entirely based on data and geometrical relationships. A second computes for any simple function relates water to...
