Abstract
The time-averaged and oscillatory solutions of the one-dimensional vertical (1DV) advection-diffusion equation for the suspended sediment have been derived analytically in a tidal sea region of finite water depth. The basic equation assumes constant eddy diffusivity and settling velocity. No net flux condition is applied at the sea surface, while a boundary condition with erosion rate and depositional velocity is prescribed at the sea bottom. The time-averaged solution have been derived in a closed form, while the advection diffusion equation governing the oscillatory concentration has been obtained in a series form using the Galerkin-eigenfunction method. A possible use of the solution to make an estimate of the erosion rate at the sea bottom based on the concentration information at the sea surface is discussed.
