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...
Watershed algorithm as was introduced by Vincent and Soille is a segmentation algorithm based on the inundation process of the image gradient which is observed as a relief. It aims at finding the peaks in the image gradient called watersheds and identifying them as the image contours. Due to its flexibility and rapidity, this algorithm is used in several applications. However, its main drawback...
We describe the background, architecture and implementation of a user portal for the SCOOP coastal ocean observing and modeling community. SCOOP is engaged in real time prediction of severe weather events, including tropical storms and hurricanes, and provides operational information including wind, storm surge and resulting inundation, which are important for emergency management. The SCOOP po...
• wavelets are analysis tools for time series and images • as a subject, wavelets are − relatively new (1983 to present) − a synthesis of old/new ideas − keyword in 29, 826+ articles and books since 1989 (4032 more since 2005: an inundation of material!!!) • broadly speaking, there have been two waves of wavelets − continuous wavelet transform (1983 and on) − discrete wavelet transform (1988 an...
For each earthquake, a set of source parameters must be chosen that determines the initial condition for propagation modeling. Earthquakemagnitude is the primary parameter that links other source parameters such as rupture area and average amount of slip. Unlike deterministic modeling in which recurrence rates are not considered, probabilistic modeling requires the determination of recurrence r...
Disas ter p reparedness o f a megacity is enhanced by disaster preparedness of its communities. This case study shows how flood preparedness in the high-risk communities of Jakarta can be achieved through a combination of understanding their risks, preparing for disasters, and by improving the early warning of incoming inundation. What’s inside 1 Hazard and socio-economic profile of Jakarta 1 H...
The high productivity stems from the annual inundation by the Mekong River of the large floodplains found in central Cambodia around the Great Lake, Tonle Sap, and the Mekong floodplains northeast and south of Phnom Penh, where important fish habitats such as flood forests are found (Figures 1.1 and 1.2 page 16). Huge seasonal migrations take place between these floodplains and spawning grounds...
