GIS Based Hybrid Computational Approaches for Flash Flood Susceptibility Assessment

GIS-Based Spatial Mapping of Flash Flood Hazard in Makkah City, Saudi Arabia

Flash floods occur periodically in Makkah city, Saudi Arabia, due to several factors including its rugged topography and geological structures. Hence, precise assessment of floods becomes a more vital demand in development planning. A GIS-based methodology has been developed for quantifying and spatially mapping the flood characteristics. The core of this new approach is integrating several top...

A GIS-based Flood Risk Assessment Tool: Supporting Flood Incident Management at the local scale

Flash Flood Forecasting: An Ingredients-Based Methodology

An approach to forecasting the potential for flash flood–producing storms is developed, using the notion of basic ingredients. Heavy precipitation is the result of sustained high rainfall rates. In turn, high rainfall rates involve the rapid ascent of air containing substantial water vapor and also depend on the precipitation efficiency. The duration of an event is associated with its speed of ...

The Securitization Flash Flood

What caused the flood of securitized products in the years immediately preceding the crisis? This paper presents evidence that demand for safe collateral in repo markets made it attractive for financial institutions to issue securitized products. Using the 2005 Bankruptcy Abuse Prevention and Consumer Protection Act (BAPCPA) as a natural experiment that shocked the demand for collateral, this p...

GIS and Flood Inundation Model-Based

Abstract: This paper presents the methodology and procedure for flood risk assessment using GIS and flood inundation model (FIM) based on the “micro-zonation concept” in which an entire floodplain considered is divided into numerous unit areas (meshes or grids). In this study, Shinkawa-river floodplain around Nagoya City of Aichi Prefecture in Japan an urbanized lowland area, which was greatly ...
