Quantitative flood hazard assessment methods: A review

Flood hazard assessment is a fundamental step in flood risk mapping. Quantitative requires hydrodynamic modelling of the flooding process order to calculate spatial distribution suitable indicators representative intensity and frequency, hence its potential result harm. are usually defined by combining relevant parameters, mainly depth flow velocity, but also arrival time, duration, sediment or contamination load, so forth. A classification commonly introduced assign level areas potentially subject flooding. This article presents systematic review quantitative methods proposed scientific literature prescribed government authorities assess associated with natural anthropic listed compared specifying their underlying approach (heuristic, conceptual, empirical), exposed element which they were designed for (people, buildings, vehicles, etc.), fields application (river overflow, dam-break, levee breach, debris flow).
