In this study, propeller current meter is used to measure the layering current velocity of an annular flume under different water depths and rotating speeds, by which we can obtain the characteristics of the flow field. There exists nonnegligible secondary flow in the annular flume, and its...

... are located at water depth 5 m, 7 m and 10 m (under the theory of datum) respectively during spring tide were calculated and analyzed. The results show that the sewage will soon be diluted after discharged into the sea. The envelope areas for both 500 and 200 dilutability contour isoline are small...

..., and then the validated method is used to simulate the cavitation flows around the same hydrofoil oriented with several attack angles (Ak = 2°, 5° and 8°) under various water depths (H=0.07m, 0.10m and 0.13m). The foil's drag coefficients, total vapor volumes and the cavity shapes of these free surface cases are compared...

... on a rubble mound foundation are investigated. The effects of several significant dimensionless parameters including the relative foundation height, the relative chamber width, the relative water depth, the wave steepness and the porosity of perforated wall are examined, using single-dimensional correlation...

... type equations which include also time dependence, weak nonlinearity and dispersion provide a means for studying wave propagation over a slowly varying bathymetry. The first such set of equations for variable water depth was derived by Peregrine(1967), which are referred to as the standard Boussinesq...
