This report determines: a) the flooding thresholds at which various types of floodplain forest may become destressed and b) the maximum extent of potential dieback for various scenarios.  It is not linked to the sediment transport model and consequently can not predict the areas of dieback, only its maximum possible extent based on topography and vegetation type.

This report details the results of a study into future vegetation dieback extent in the Ok Tedi and Fly River floodplains.  Initial estimates of future extent were reported as part of the 1999 HERA studies, and this report aims to update those estimates with respect to pessimistic, likely (dredging to mine closure) and likely (no dredging) scenarios.
