heal.abstract	One of the most favorable and cost-saving methods to counteract water quality deterioration in a harbor basin is the use of flushing culverts, which reduce flushing times and avoid areas of low flow and eddies formation. In the present paper, results of experiments carried out in a 2-D facility in order to investigate wave and dissolved oxygen transmission in harbor basins through flushing culverts are presented and analyzed. Incident wave and transmitted wave heights were determined using wave gauges for various combinations of wave characteristics and geometric characteristics of the flushing culverts. An empirical equation using regression analysis was derived, which correlates the wave transmission coefficient with the characteristics of the waves and the geometrical characteristics of the flushing culvert. Further the oxygen transmission coefficientthrough flushing culverts, was expressed as a function of the characteristics of waves and the dimensions of the flushing culvert. The comparison of calculated and experimental data is very encouraging. Though, the verification of the proposed equation with even more extended experimental data and real scale measurements is needed in order to be used in the design process. © Copyright 2010 Global NEST Printed in Greece.
