Instead of filling 1D profiles with only one set of phi parameters left and right bank, we need a 2D model. Rough idea is to make a bi-directional model that models the ordinal location of the deepest point as function of the longitudinal coordinate. Going from up to downstream, the conveyance should stay the same. Hence as the grid becomes more (less) wide, the deepest point should de(in)crease.
