To extend the level that the HQ relationship is calculated for an automatic HQ boundary there are two options:
* Extend the HQ line to higher grounds.

* The 2d_bc “d” attribute can be used to set the maximum depth of the automatically generated HQ curve (note d is a depth, not an elevation). This option assumes glass walls at the edges of the HQ line, e.g. there is no additional flow area to the sides, it does not take into account the increase in floodplain storage as the water surface level goes up. This might artificially inflate water surface levels immediately downstream and understate the flood extent.

For both suggestions, HQ curve would be automatically extended:
