The effectiveness of groyne systems. Physical model study of groynes on a beach (EX 1351)

This report covers a programme of physical model tests carried out as part of Phase II of a research project investigating the effectiveness of groyne systems in modifying the beach environment.
The physical modelling was assisted by two field surveys undertaken in November 1983 and October 1984 at Sea Palling in Norfolk. The aim of the programme was to calibrate the physical model using the prototype field data and then study the effectiveness of the Sea Palling groyne system. Following this, various other groyne layouts would be tested and their effectiveness checked by varying groyne parameters and flow and wave conditions and identifying their effects.
