Zusammenfassung |
This work presents a two-dimensional horizontal plane
model of seawater intrusion into a heterogeneous coastal unconfined aquifer
under the spatially random recharge condition from a stochastic point of
view. The stochastic response of the coastal unconfined aquifer is
attributed to uncertainties related to the heterogeneity of aquifer
properties and spatial variability of the recharge. Based on the
sharp-interface assumption, analytical expressions for the variances of the
seawater-freshwater interface elevation and specific discharge in the
longitudinal and transverse directions are developed using the perturbation
approximation and spectral Fourier-Stieltjes nonstationary representations.
We focus on the study of the impact of the heterogeneity of aquifer
properties and recharge on these results. |
