1. A computer implemented method for correlating data predicted by a process-based model or physics-based model to describe a subsurface region with known data describing the subsurface region, the method comprising:

  • obtaining data describing the subsurface region;

    estimating model parameters of an initial state of the subsurface region;

    predicting data describing a subsequent state of the subsurface region with a computer, wherein the predicting data comprises using the model parameters to simulate with a model the evolution of a channel by modeling dynamics of interplay between channel migration and changing sedimentary environment;

    comparing the predicted data with the obtained data by computing an objective function taking into account whether the predicted data represent a discontinuous event, wherein the objective function is defined using the following formulation;
