Abstract

Water wave over a porous sea bottom drives a seepage flux into and out of the sediment. The exchanged flux per wave cycle may be tied to the mass transfer rate of contaminant in sediment. In this paper, an analytical solution of seepage flux is sought based on Biot theory of poroelasticity. Sensitivity analysis is conduction with respect to sediment parameters as well as the degree of saturation. 1 Introduction Sea bottom sediment in bays, estuaries, and in ocean near river outlet is often contaminated. Many inorganic contaminants, most notably heavy metals, do not decompose. These accumulated substances are released back into the receiving body of water through bottom
