✦ Synopsis
Water wave over a porous sea bottom drives a seepage #ux into and out of the sediment. The volume of #uid exchange per wave cycle and per wave length may be tied to the mass transfer rate of contaminant in sediment. In the "rst part of the paper, the analytical solution of seepage #ux is presented based on the Biot theory of poroelasticity. Parameter e!ect on the seepage #ux as well as on the pore pressure is examined. In the second part, empirical relationships are introduced to reduce the data requirement of the model to two parameters: the porosity and the degree of saturation. With the existence of a multi-sensor piezometer known as &MPAS', the pore pressure data in the sediment can be collected. Utilizing the empirical relations, parameter inversion can be achieved based on pore pressure data alone.
