Unformatted text preview: first step towards uncertainty analysis (next section), let us develop further the statistical analysis of the simulated salt wedge, based on single replicate unconditional simulations obtained on the largest grid (1000 × 1000 cells). The salt wedge is characterized by the shape of the saltwater interface elevation ZSALT(x,y) and its horizontal extension inland. We consider ZSALT(x,y) as a random field and we analyze it statistically. We focus in particular on the first and second order moments of ZSALT(x,y), including its mean and its standard deviation. This analysis is applied to the 1000x1000 grid, with large variability (σlnK = ln10). Given the symmetries of the problem and the statistical stationarity of K(x,y), we expect the surface ZSALT(x,y) to be stationary (statistically homogenous) along the y direction parallel to the seashore. However, it will not be stationary along the x direction parallel to flow (transverse to seashore). Indeed, Fig. 5 shows 100 transects ZSALT(x,yn) along with the average profile, all plotted as functions of the x-coordinate (perpendicular to sea shore). The profiles ZSALT(x) are clearly nonstationary. 6 Stochastic an...
