Unformatted text preview: 4 depicts the effect of heterogeneity level on the mean penetration of the salt wedge, for a
300 × 300 grid. The mean ZSALT(x) profile is plotted versus distance from sea (x), after averaging
ZSALT(x,y) along the shorewise direction (y). The three profiles correspond to: σlnK = 0
(homogeneous), σlnK = 1 (moderate heterogeneity) and σlnK = ln10 (high heterogeneity). As the level
of variability σlnK increases, the mean elevation ZSALT(x) increases and the mean salt wedge
penetrates farther inland. The extra penetration of the mean wedge due to heterogeneity is about
200 m, for the most heterogeneous case.
A similar result (not shown here) was obtained for the larger 1000 × 1000 grid with heterogeneity
levels σlnK = 0, 1.0, √2, 1.6, and ln10. It confirms the monotonic increase of the mean penetration
length of the salt wedge as σlnK increases, compared to a homogeneous aquifer with geometric mean
