Unformatted text preview: LT parallel to the seashore and plotting the resulting moment σZ as a function of
distance (x) from the sea. One result is shown in Fig. 7 for large heterogeneity (σ=ln10). The
standard deviation of ZSALT seems approximately stationary far enough from the seashore (x = 0) and
far enough from the salt wedge tip (x ≈ 700 m). In the stationary region of Fig. 7, we find
σZSALT ≈ 1.3 m. The 95% confidence band of the salt interface is several meters, which represents a
rather significant fraction of the total aquifer thickness of 30 m. Modélisation stochastique de l'intrusion saline en 2D plan 68 Fig. 6 One hundred transects of ΦSALT (transformed from ZSALT); “analytical mean” curve ΦSALT (homogeneous
aquifer); and "numerical mean" curve ΦSALT (mean of ΦSALT sampled shorewise along “y”). The sea shore is at left.
Grid: 1000x1000. Heterogeneity: σ = ln(10) The results appear different for lesser heterogeneity: see Fig. 8 for σ = 1.60, and note that similar
results were obtained for σ in the range 0 ≤ σ ≤ 2.0. In al...
