Bedform data at 4 shallow zones in the Yellow Sea where waves as well as tidal range are high and bed material is relatively coarse were collected and analyzed here. Water depths in the study area where the bedform data were collected are 10 ~ 65 meters, and ripple lengths well developed are between 6 ~ 13 meters. Existing empirical formula for prediction of ripple length as for coexistence of waves and currents include Khelifa and Ouellet(2000) and Soulsby(2005), both of which have been based on laboratory measurements, or field measurements at different physical environment from the Yellow Sea with respect to tidal range, wave strength, and bed material. New scaling factors are proposed here for better prediction of the ripple length on coastal zone in the Yellow Sea.
