This paper proposed an improved prediction method of inland waterway vessel noise considering the effects of water surface adsorption and embankment shielding. The method was established on the basis of the UK Calculation of Road Traffic Noise (CoRTN) method, and the effects of water surface adsorption and embankment shielding were integrated into the governing equations. The developed method was validated using the data measured at the 40 monitoring points along Da Yunhe Channel in China. The results showed that the improved method had a higher accuracy and precision than that of the unmodified CoRTN method. The predicted noise exposure level by the unmodified CoRTN method correlated with the measured values with an R2 of 0.74569, which was enhanced to 0.86457 by the improved method. The current research is the prime to forecast river vessel noise level on the basis of the CoRTN method considering water surface adsorption and embankment shielding influences in China. It is expected that the modified method could be a new tool for estimating vessel noise effect on the inhabitant around the urban inland waterways.
