A Study on the Variation of Streambeds Surrounding the Piers according to the Established Patterns of Hydraulic Structures

수공구조물 설치 형태에 따른 교각주변의 하상변동에 관한 연구

As part of a new riverside development project, various types of bridges and covering bridges were constructed in natural river estuary; and these structures got in the way of the flow of the river, which has resulted in a topographical change in natural river estuary, decrease in the gross sectional area of flow, and rise of water level. As a result, surrounding areas are suffering from damages due to overflowing of river over the bank. This study was designed to provide basic data for efficient design of structures, by examining resistance and characteristics in the surrounding areas of bridges based on changes in the span length ratio.
