Abstract
The time-dependent one-dimensional vertical (1DV) conservation equation of sediment has been solved analytically in a tidal sea region. The basic advection-diffusion equation assumes constant eddy diffusivity and settling velocity of sediment particles. No net flux condition is set at the sea surface, while one of two kinds of bottom boundary conditions can be prescribed according to the bed condition including the sediment type. Flux-type bottom boundary condition with erosion rate and depositional velocity has been applied to mud beds, while the condition of reference concentration to sand beds. The governing advection-diffusion equation has been first transformed to a simple diffusion equation and then solved using the Galerkin-eigenfunction method.
