Adding parameterized floodplain

nmizukami commented 6 months ago

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

This PR does not affect any current model simulations and performance since the new module is not hooked up with any others).
