1. A method of detecting and correcting for discrepancy events in a fluid pipeline, the method comprising:

  • obtaining a plurality of empirical temperature and pressure measurements at a plurality of locations within the pipeline;

    simulating, using a pipeline model, a plurality of simulated temperature and pressure measurements for the plurality of locations within the pipeline;

    detecting, by a discrepancy event detector, at least one discrepancy event representing a discrepancy between the empirical temperature and pressure measurements and the simulated temperature and pressure measurements;

    outputting to a user an indication that the at least one discrepancy event has been detected;

    accounting for the discrepancy;

    determining, after the accounting and using an estimator applied to the pipeline model, a corrected branch flow rate for the pipeline; and

    outputting the corrected branch flow rate for the pipeline to the user.
