Line 131: [[File:FMA3_7.jpg\|600px]] The 100ft and 200ft simulations were re-run with Green-Ampt infiltration switched on. The resulting peak flood depths map for the 100ft simulation is shown in the image below (right) whilst the 100ft without infiltration is provided on the right. As can be seen, the extent of inundation is significantly reduced with floodwaters infiltrating before reaching the model extents or returning to the main channel. The mass balance reporting from TUFLOW indicates over half (58%) of the water infiltrates into the ground during the 171 hour simulation. This reduction in volume can also be observed via the “100ft GA” flow hydrograph show above.
