The run-up, under wind action, of wind-generated waves on levees with slopes of 1:3 and 1:6 was studied in a laboratory wind tunnel. For the lower wind velocities the results indicate the same relative run-up values as found at the Waterways Ex¬periment Station, Corps of Engineers, Vicksburg, Mississippi, where the tests were completed with mechanically generated uniform waves which were not affected by wind. For higher wind velocities, however, the run-up increases with increasing wind velocity and may reach double the value (above mean water level) of run-up where no wind is involved. Run-up on the 1:3 slope was found to be considerably higher than that on the 1:6 slope (by a factor of approximately 2.5), which confirms the trend as found at the Waterways Experiment Station using uniform waves
