한국어 초록
The levee and bridge pier in estuary of the Hangang River are exposed in a dangerous condition due to bank erosion andlocal scouring occurred since the summer season in 2011. At first, it is presumed that the high sandbar formed in riverchannel of the study area was an important element in the occurrence of bank erosion and local scouring. It can bepresumed that the record-breaking depth of freezing due to cold wave for the long term during the winter season between2010 and 2011 as well as the heavy intensive rainfall of 2011 had a decisive effect on the first damage of A section. Thesecond damage of B section mainly occurred around the bridge pier constructed on the high water channel before it waswashed away during the winter season between 2011 and 2012. It is considered that the second damage was caused by iceformation and ice floes.영어 초록
