Unformatted text preview: location (x,y), within the salt wedge or not. The freshwater transmissivity
T(x,y) is then inferred from freshwater thickness η(x,y) as follows :
T ( x, y ) = K ( x , y ) × η ( x, y ) (30) Note that T is spatially variable via K and ZINF , and also, nonlinear via the unknown variables H
and ZSALT on which it depends. Finally, we obtain the following system of vertically integrated flow
equations (steady state case):
1. Steady-state mass conservation (freshwater):
= −div (Q) where Θ is the water content
∂t 2. (31) Darcy’s law (vertically integrated):
Q = -T (H,Z SALT ,Z INF ,x,y ) grad(H ) (32) Modélisation stochastique de l'intrusion saline en 2D plan 3. Freshwater transmissivity:
T= 3 60 K(x, y) ×(H − ZINF(x, y)) if ZSALT < ZINF
K(x, y) ×(H − ZSALT(x, y)) if ZSALT ≥ ZINF (33) Unconditional Random Aquifers (Single Replicates) In this paper, we choose to study uncertainty without regard for specific data. That is, we choose to
simulate seawater intrusion in large unconditional single-replicates of the heterogeneous aquifer. We
use the XIMUL code to generate isotropic log-norma...
