Integrated sand control inclu
ding sediment discharge from hinterland rivers is necessary to maintain coastal sand resourcesover a long term. In this regard, the following subjects should be considered; efficient ways to transfer discharged sandfrom a river to the neighboring coast, measures to improve storage efficiency of the discharged sand at the river deltaand/or river terrace, measures to prevent the sand resources from being discharged into the deep sea during flooding. Fromthe 1997 to January 2004, the jetty of 156 m length was constructed the Heoya-river mouth to protect the blockade of rivermouth. Several tests were carried out to investigate the characteristics of sediment transport and morphological change dueto the construction of the jetty at the Heoya-river mouth. Firstly, The sand discharge from Heoya river is quantified byone-dimensional numerical analysis assuming the mixed sand of three different particle diameters. Also the numerical modesystem, which predicts the sea bed changes obtained from the Bailard's energy model(1981), was combined with the wave,wave-induced currents and sediment transport models. Then, to understand the changes to the blockade of the river mouth,several aerial photographs were compared, which showed that the changes were significant.   (ÀÌÇÏ »ý·«)
