Stochastic parameterisation

SPRING allows the stochastic generation of spatially correlated or non-correlated input parameters like hydraulic conductivity.

1. Stochastic generation of (spatially uncorrelated) data

Stochastically generated parameter (following a defined function) are assigned to all or individual nodes respectively elements of a layer.

2. Stochastic generation of spatially correlated data

Spatially correlated data are generated using a “turningband” algorithm (exponential approach). The interpolation accounts for the similarity of data as a function of their proximity and spatial correlation lengths may vary in three dimensions.
