Abstract: Kajiura's three-layer model (1968) of an oscillatory rough turbulent layer is simplified to a two-layer model. This model consists of an overlap layer in which the turbulent viscosity varies linearly with height, and an outer layer in which the viscosity is constant. The analytic expressions are compared with Jonsson's Test No. 1 (1963, 1976, 1980). Reasonable agreement between theory and experiment is found, thus supporting the usefulness of the two-layer model.
