Coastal Processes and Management in Different Environments
Lakeshores
The coastal group has a long association with lakeshore management being involved since the early 1970s at Lakes Manapouri and Te Anau. Management of issues on the shorelines of lakes used in hydro-electric power schemes is a speciality, including investigations of hazards and their mitigation, prediction of shoreline development on new and changing lakes such as Lake Dunstan, studies on longshore transport at Lake Colleridge, and information on lakeshore processes and morphologies for resource consents at Lakes Mahinerangi, Manapouri, Monowai, Pukaki, Te Anau and Waikaremoana.
Shore Platforms
The coastal group also has a 30+ year record of erosion of shore platforms at Kaikoura. The network of erosion bolt sites was installed in 1973 by Bob Kirk and updated in 1993 by Wayne Stephenson (now at University of Melbourne). This work has been extended by Anna Taylor for her Ph.D. thesis (2003), which included studies of shore platform development at Akaroa and Lake Waikaremoana, comparing limestone, 'hard' mudstone, greywacke, basalt and 'soft' mudstone lithologies in a variety of wave environments. The Lake Waikaremoana work is part of an ongoing monitoring program to examine shore change to assess the effects of lake level management.
Fast Ferry Wakes
Martin Single is involved with ongoing studies as to the effects of wake waves from fast ferries travelling through Tory Channel and Queen Charlotte Sound. This is a very public issue as these vessels form part of the transport link between the North and South Islands and have been considered an essential service. However the effects of the wakes have been perceived by some as damaging to the environment and as a danger to users of the area. Of particular interest are the actual effects to the physical coastal environment, the sustainability of the activity, and the possible consequences of slowing these ferries. Martin is a member of the PIANC technical working group (WG41) which has recently completed a publication on guidelines for management of high speed craft.
