Construction of man-made embayments in riparian areas to provide natural friendly environment have attached an increasing interest in Japan. In this study, experimental and numerical studies were carried out to clarify the momentum transfer process in embayments of various entrance shape under low water steady flow conditions. Velocity measurement showed that while the mixing layer along the embayment - main channel interface and the recirculation pattern in embayments change considerably depending on the hydraulic conditions, time averaged velocity shows little variation in magnitude and flow direction over the flow depth. Hence, a numerical model based on shallow water equations incorporated with the depth-averaged κ-ε model was developed for the analysis of depth-averaged velocity field. It was confirmed that the numerical model can yield the mean velocity distributions in good agreement with experimental data.
