"Due to budget and timeframe constraints,
and the technical challenges posed by the large spatial coverage and the
extended period for simulation, it was necessary to make a number of
simplifying assumptions. Some of the assumptions do not reflect real
conditions, leading to a lack of allignment with existing field
measurements!!
Consequently, the sediment plume and transport maps provided in this report do not represent actual sedimentation rates or the specific extent of dredge material dispersion and migration."
As quoted by the GBRMPA Interpretive Statement on page 6!
"This study investigated the migration of dredged sediments during placement operations (not dredging) and over 12 months when placed at existing and hypothetical alternative placement sites at six study locations. The sediment plume modelling was based on relevant hypothetical placement scenarios established in cooperation with port operators but do not represent specific past or proposed dredging campaigns.

As quoted by Dr Brett Kettle , who has over 30 years experience in the field of dredging - "The furthest ecological effects of dredging had ever been seen away from the dredge sites was 10km"
