Abstract: Wind tides and wave conditions in shallow water were studied in a laboratory channel. The experiments were conducted with smooth and rough bottom conditions, and with strips of cheese cloth in the channel to simulate the roughness effects of vegetation in nature. The results indicate a rapidly increasing set-up when the still-water depth decreases below a certain limit. There were no indications that the bottom roughness affects the set-up for relatively deep water; in very shallow water, however, the rougher bottom conditions result in higher set-ups. The trend is especially pronounced for higher wind velocities. For the shallowest still-water depth (0.0, foot) used in the experiments, the set-up was approximately 10 percent higher for the rough bottom, and approximately 20 percent higher when strips of cheese cloth were used in the channel to simulate the roughness effect of vegetation, than the set-up observed with a smooth bottom.
