Version 0.5.0

Version following initial completion of methods section of paper and distribution to coauthors.

• Major Enhancements
  • Bed-load diffusion: Full overhaul. Stochastic lateral motion due to particle collisions
  • Noncohesive erosion: time of flight, and therefore, particle step length. This makes $k_E$ dimensionless.
  • Double Manning can now use hydraulic radius or depth; the latter uses the wide-channel assumption.
• Minor enhancements
  • Critical Shields stress (tau_star_c_sed) is now user-definable
  • Lump all shear-stress and shear-velocity variable computations into a single function in which they are updated; call this at an early point while updating width. See: Centralize update of stress, shear, and turbulence variables: Prior to widening, narrowing calculations.
  • Plot db_dt__day__narrowing_series as negative.
  • Add legend_loc option for plotting; legend fontsize=12
• Fixes
  • Plotting works with updated Pandas (indexing deprecation)
  • Fix function compute__u_star__tau_bed: Remove 1/2 power from self.tau_star_bed calculation in (self.rho_s - self.rho).
  • Let self.tau_star_bank not be defined if D is None.
