Early warning of impending flash flood based on AIoT

A Conceptual Flash Flood Early Warning System for Africa, Based on Terrestrial Microwave Links and Flash Flood Guidance

A conceptual flash flood early warning system for developing countries is described. The system uses rainfall intensity data from terrestrial microwave communication links and the geostationary Meteosat Second Generation satellite, i.e., two systems that are already in place and operational. Flash flood early warnings are based on a combination of the Flash Flood Guidance method and a hydrologi...

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 ...

An Integrated Simulation and Distribution System for Early Flood Warning

This research presents an integrated system of computer software, networking and web-based display developed and deployed to allow drainage management authorities immediate access to results from the Weather Research and Forecasting (WRF) Hydrological Extension model, WRF-Hydro. Output data from the model are analyzed by a chain of GIS, database and web publishing tools to forge updated and rea...

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...
