DESCRIPTION
Matlab code to run the 2D sediment transport and accretion model. The model uses a pre-computed hydrodynamic simulation to calculate sediment transport and accretion. Modeled processes are advection, settling, entrainment, and evolution of the bed grain size distribution. Parameters such as the sediment settling velocities "w_s" can be modified directly in the main file "SSC_parallel_10fM_fixfriction_dx50.m", which by default uses a mud settling velocity of 0.1 mm/s. The code uses separately modeled hydrodynamics from ANUGA. The hydrodynamic input file is "velocity_50m_nocrop_newversion_fixfriction.mat" and is loaded automatically when running the main script. All other functions are automatically called from the main file. The simulation is run sequentially five times using the same hydrodynamic input file to allow the bed composition to come to an equilibrum.
