Evaluation of Coastal Process Impacts Arising from Nearshore Aggregate Dredging for Beach Recharge – Shingles Banks, Christchurch Bay

This paper describes how aggregate dredging within coastal zones may create a range of conflicts, uncertainties and opportunities. The demand for high quality aggregates from offshore sources is high, especially for beach recharge. However, there is considerable concern, particularly from Local Authorities, that the dredging will have adverse impacts on coastal zones. The paper examines the results of a monitoring program that was conducted in compliance with license conditions for the Shingles Banks dredging area. The results are examined in context with predictions that were derived from pre-dredging coastal process impact studies. Trends are examined by reference to control data sets that were derived in conjunction with Local Authorities’ best practice coastal zone management programs. The significance of high quality baseline data, validity of modeling methods and the appropriateness of measurement techniques are also examined.
