Indexing of Flash Flood Risks

  • DEM, ~100 m: Jordan
  • cutting out the region of interest: Petra
  • defining an (moving) analysis box: 20 x 20 = 400 Pixel
  • Parameter:
    • Hill (Zmax-Zx): 100 m
    • Valley: 50 m
    • Total Rainfall (TP): 300 mm = 0.3 m
  • scaling of the elevation data by the minimum within the box (i)
  • calculating the percentile of the valley (PV) within the box
  • INDEXi=TPi/PV
  • The sum of rainfall in the box is distributed over the number of in the valley
  • Processing and Mapping in the order of minutes (operationalizable)
