Abstract

Two experiments were undertaken to study the effectiveness of a remediation system that utilizes prefabricated vertical drains. The measurement program, which included obtaining head and concentration measurements for these experiments, was designed using a Bayesian decision framework. The First-Order Second-Moment Bayesian method was employed to select the best location for the observation wells as well as when to take the measurements and how long the experiment should last. The selected measurementscheme balanced the reduction in uncertainty realized through taking the head and concentration measurements with the difficulty in obtaining those measurements.
