Permeable paving needs to have a option for a different gradient at the surface to the gradient at the base.

This would allow a better representation of steep sites where we would otherwise lose a lot of storage, instead we can make the base flat to allow for more storage volume.

    This feature would also be enhanced with an option to specify the exceedance and base level of the paving, at both the upstream and downstream end, thus allowing for a trapezoidal shape to the sub-base. This would allow a more realistic model of pavements that use check dams/baffles in the sub-base.
