WP7.5 Model Parametrization and Validation
Moving boundary scheme
Cell is dry or wet
Position of the shore line
If Hi > 0 :
If Hi+1 ≤ 0 and hi+1 + i ≤ 0  Shoreline remains between i and i+1 and
If Hi+1 ≤ 0 and hi+1 + i > 0  Shoreline moves between i+1 and The flooding depth is Hf = hi+1 + i
If Hi+1 > 0  Shoreline moves between i+1 and i+2, The flooding depth is Hf = max (hi+1 + i, hi+1 + i+1)
