One-line model description Wave-phase resolving numerical model for fluid mud transport
Extended model description This is a 1DV wave-phase resolving numerical model for fluid mud transport based on mixture theory with boundary layer approximation. The model incorporates turbulence-sediment interaction, gravity-driven flow, mud rheology, bed erodibility and the dynamics of floc break-up and aggregation.

Process description model
Describe processes represented by the model wave-current boundary layer and fluid mud transport. dilute suspension. wave-supported gravity-driven mudflow. turbulence modulation due to sediment. tidal-driven fluid mud transport. Floc dynamics. Rheology.
Describe key physical parameters and equations mixture equations (derived from two-phase theory with fine sediment assumption). k-epsilon closure derived from two-phase theory. Bingham rheology. Floc property is based on fractal structure. Bottom boundary condition for mud is based on type I erosion.
