Abstract
From the past, earning living of the people in the lower of Mekong River has been acquainted with the ships and boats in the density river system. Gradually, waterway has become the key factor for area developing, intensity of commercial, and recreational navigation. Inland movement of the cargo ship brings a significant efficient on cargo shipping which impulses the regional economic development. However, impacts from inland movement should be considered seriously. The drawn followed by ship movement put a pressure on the riverbanks which causes turbulence and erosion potentially. This paper carried out several field measurements on bank structures and ship movements to assess the potential impacts of ship-induced wave on Hau River’s entrance navigation. As results, the riverbanks could resist the external shear stress by maximum wave height from 40 to 60 cm.
