Abstract

A micro shear gauge was used to measured the bottom shear stress under the shallow water wave on the smooth bed, the data show that bottom shear stress have a asymmertic form similar to the surface water elevation due to the non-linearity of wave. The bottom friction factor under wave creat and wave trough were very different with that defined by Jonsson's and the results were contrary when the bottom particle velocity were defined by linear and non-linear wave theory respectively. Empirical formula were obtained for practical use.
