Abstract

An evaluation of design factors and performance of groynes P. Dong Division of Civil Engineering, Faculty of Science and Engineering, University of Dundee. Abstract Gropes are among the oldest structures in wide use today for controlling coastal erosion. Due to the complexities of the physical processes involved, predictions of grope performance are not always reliable despite the prolific use of sophisticated numerical models. Site specific knowledge obtained from postconstruction monitoring remains an indispensable source of knowledge for engineers in designing groynes. This paper reports the analysis of a recently conducted questionnaire survey on the most important factors which influence the design of groynes and perception of the performance of existing groynes. It was found that the greatest importance was placed on the effectiveness of groynes in holding sediment locally while the least importance was placed on the negative effects that building groynes can have on both the natural an
