[Coral-List] Water Quality Thresholds for Dredging

[Richard Unsworth]

Hi All,
       does anyone know of any mainstream or 'grey' literature that is available on the development and use of water quality thresholds for the modelling and monitoring of dredge impacts upon coral reefs or other benthic primary producer habitats? I have some studies (i.e. Mcarthur et al 2002, Turner et al. 2006, Koskela et al. 2002) and associated references but actual hard information on specific thresholds and how and why they were developed seems scant within the literature, so any studies would be extremely useful! There seems to be lots of information available on the impact of dredging, sedimentation and turbidity but not about the assessment of potential impacts and the thresholds required to prevent these. Also any useful contacts for such information would also be useful.
 
Any ideas would be hugely appreciated!
 
Kind regards
 
Richard
