The information of wave setup at the entrance is useful for river authority and river engineers to find out the best solution in controlling the river mouth morphology change and environment management as well as salinity intrusion into the river. In this study, an attempt is made to collect as many full data sets as possible. In total, field observation data from eight river mouths within Japan were compiled and analyzed. The results have been shown that the height of water level rise is not only depending on wave breaking at the entrance but also affected by river discharge and river mouth morphology. Wave setup height was attained to from 2 to 14 percent of offshore wave height for the cases of water depth at entrance from 1.1m to 6.5m. The final result is obtained as a technical diagram for predicting the wave setup height at the river entrance.
