Conditioning stochastic groundwater flow models on head data

  title={Conditioning stochastic groundwater flow models on head data},
  author={K. Andrew Cliffe},
The authors present a new method for conditioning realizations of the logarithm Y of transmissivity on head data. Each realization is conditioned by subtracting a linear combination of certain basis functions, each corresponding to a measurement, obtained by a process based on co-kriging. The required cross covariance between head and Y can be numerically computed very efficiently using the adjoint method. The coefficients in the linear combination are chosen to try to minimize the differences… CONTINUE READING
