the thickness of the boundary layer. Flux calculation results showed that salt fluxes released from
the sediment can be predicted with a power function, i.e., salt fluxes decreased rapidly initially
and then stabilized with time. Observed salinity change in sediment indicates that salt release
through molecular diffusion only in drainage ditches is a slow process, which may have only
limited impact on salt balance in drainage ditches when the flushing water moves slowly. And
hydrodynamic dispersion is required to speed up release of salt from the ditch sediment in order
to remove accumulated salts in the drainage ditches in saline environment.
