Abstract
This study has analyzed the backwater effect by the bridge pier on the basis of the result on hydraulic characteristics with pier shapes in study(I), using a two-dimensional model(RMA-2) and an one-dimensional model(HEC-RAS). The pier shapes are classified into total six types such as square, rhombus, octagon, oval, round, and no-piers. The result of the backwater effect analysis showed that the backwater length is about 150 and 50m from HEC-RAS and RMA-2, respectively for all pier types. Although it is difficult to directly compare between results from the two models, the oval shape pier has shown similar results to the no-pier situation before the bridge construction in hydraulic characteristics. This analysis can help to select pier types in the new bridge construction for the future.
