| Abstract |
A method for estimation of the lateral dispersivity in a homogeneous isotropic coastal aquifer where salt-water intrusion takes place is discussed. A similarity approximation is used for both the tangential velocity along and the transverse salt-water concentration profile to the steady fresh-/salt-water interface obtained by immiscible assumption. In order to confirm the validity of the proposed procedures, a two-dimensional numerical simulation procedure is compared with experimental data. Calculated concentration profiles by the proposed method show compatibility with experimental data and numerical solutions. The present method will be useful for the estimation of lateral dispersivity in a practical case using borehole data. |
