Table 2 Assigned permeability values and ranges for the different permeability shoreline classes with an explanation.
Permeability Class | Permeability value (m²) | Permeability Range (m²) | Permeability source |
|---|---|---|---|
Sandy shore (B1 - Low Waves) | 10−11 | 10−11–3*10−11 | Value: Lowest value of beach the permeability range stated by61,62,63,64 Range: Whole range for all beach literature values stated |
Sandy shore (B2 - Mid waves) | 2*10−11 | 10−11–3*10−11 | Value: Middle value of beach permeability range stated by61,62,63,64 Range: Whole range for all beach literature values stated |
Sandy shore (B3 - High Waves) | 3*10−11 | 10−11–3*10−11 | Value: The highest value of beach permeability range stated by61,62,63,64 Range: Whole range for all beach literature values stated |
Concreted shore (P) | 10−20 | 10−20–10−20 | Considered as Impermeable |
Muddy shore (M1) | 5*10−13 | 10−13–10−12 | Value: Average of the range of literature values65,66,67,68,69 |
Mangrove shore (M2) | 5*10−12 | 10−12–10−11 | |
Rocky Shore (R) | Permeability taken from19 | The range was taken from19 | Rocky shorelines are assigned the permeability values stated by19 for that location. |
