Purpose: remove unlimited bankful depth so that water can go to flatter floodplain next to the channel.

Assumption: floodplain is the same for both sides. channel geometry is known shapes (rectangular, triangular, trapezoidal)

Main code changes:

  • Add a routine to compute channel hydraulic properties (top of channel width, flow area, wetting perimeter, uniform flow, normal flow depth, celerity, and diffusivity)
  • Add a bankful depth, channel side slope, and flood plain slope to channel geometry
