29 Jan 1976TL;DR: In this article, the direction of net sand transport depends upon the form of the waves, and the measured sand transport is related to the measured wave form parameters, and it is shown that the transport has been measured by means of a special procedure which does not disturb the process.
Abstract: Sand transport parallel to the direction of wave propagation by waves of arbitrary form over a rippled bed has been investigated in a flume, at the Laboratory of Fluid Mechanics of the Dept. of Civ. Eng. of the Delft Univ. of Techn. The transport has been measured by means of a special procedure which does not disturb the process. The measured sand transport is related to the measured wave form parameters. The results indicate that the direction of net sand transport depends upon the form of the waves.

TL;DR: In this paper, a two-dimensional NumErical Water Flume (NewFLUME) is proposed to simulate a wider range of free surface flows (e.g., surface waves, jets and open channel flows) and their interaction with different types of bodies, impermeable or porous, stationary or in motion.
Abstract: A computer model has been developed to simulate general turbulent free surface flows. The model solves Reynolds equations for turbulent flows and employs the volume-of-fluid method to track free surfaces. Being the extension of the earlier works for simulating breaking waves [e.g., J. Fluid Mech. 359 (1998) 239; J. Waterway Port Coastal Ocean Engng. 125 (1999) 322], the current model has been generalized to simulate a wider range of free surface flows (e.g., surface waves, jets, and open channel flows) and their interaction with different types of bodies, impermeable or porous, stationary or in motion. The model essentially serves as a two-dimensional NumErical Water FLUME (NEWFLUME) for simulation of various flow phenomena. Compared with a physical wave flume, NEWFLUME is more efficient in problem setup and data acquisition. In this paper, the applications of NEWFLUME to different hydraulic problems are demonstrated with the use of a series of selected case studies. These case studies cover the fields of...

TL;DR: In this article, a series of experiments have been carried out in the large wave flume (LWF) at Oregon State University to quantify tsunami bore forces on structures and the resulting forces and pressures on the wall were measured.
Abstract: A series of experiments have been carried out in the large wave flume (LWF) at Oregon State University to quantify tsunami bore forces on structures. These tests included “offshore” solitary waves, with heights up to 1.3 m, that traveled over a flat bottom, up a sloping beach, and breaking onto a flat reef. Standing water depths on the reef varied from 0.05 m to 0.3 m. Resulting bores on the reef measured up to approximately 0.8 m. After propagating along the reef, the bores struck a vertical wall. The resulting forces and pressures on the wall were measured. The test setup in the LWF is described, and the experimental results are reported. The results include forces and pressure distributions. Results show that the bores propagated with a Froude number of approximately 2 and that the forces follow Froude scaling. Finally, a design formula for the maximum impact force is given. The formula is shown to be an improvement over existing formulas found in the literature.
