Quantitative Study on Beach-Face Slope Based on Field and Laboratory Experiments

摘要

State-of-the-art beach profile data sets including field measurements and laboratory experiments are applied to investigate the predictions of beach-face slope. Field measurements of beach profile and sediment characters yield a logarithmic-type of model to link beach-face slope and sediment grain size, while a series of laboratory experiments data sets which contains hydrodynamic forcing are compared with formula suggested by Sunamura (1984), and certain discussions and improvements are proposed regarding to the quantitative predictions of beach-face slope.
