Line 58: This does raise one issue indirectly of flood mapping in urban areas where the flood depths are very shallow, or if using direct rainfall modeling. In these instances, mapping of urban areas may specify that flooding must be of a minimum depth to be mapped. For example, where the flooding is less than say, 0.05m, it is not mapped. ==Manning's 'n' Values== The adopted Manning’s 'n' values were based on ~~the~~ aerial ~~photo~~photography and structure photos asand are tabulated below. A sensitivity simulation was carried out increasing the Manning’s 'n' value along the main channel from 0.03 to 0.04. The results for the sensitivity simulation are provided in the long-profile of maximum water surfaces along the channel (depth grids and other data can be provided upon request). The maximum increase in peak water level along the profile is 1.94 ft.<br> {\| align="center" class="wikitable" width="50%"
