FloodRisk- QGIS plugin that provides the assessment of flood consequences,in terms of loss of life and direct economic damages.

The tool performs a simple risk assessment in which it consider fixed event scenarios where the probability of each scenario is estimated separately and it calculates the consequences deterministically.

• Direct economic damages estimation.

  The damage to residential, commercial and industrial property is assessed using depth–damage curves, which describe the relationship between levels of inundation and damage incurred

• Population at Risk and Loss of Life estimation

  In "FloodRisk" the first step for the loss of life estimation is to obtain the map of the population at risk by superimposing the inundation map and the population density map. Once calculated the map of the population at risk, the number of potential fatalities is obtained by multiplying population at risk time the fatality rate. The tool allows the user the choice of the fatality rate between two of the available scientific methods:

  • US Department of Homeland Security (DHS 2011)
  • SUFRI Methodology for pluvial and river flooding risk assessment (Escuder Bueno et al, 2011
