| In this study, area variation, index and degree of alteration, temporal variation of the sandbar and vegetation were analyzed using aerial photographs during the pre and post dam construction at the downstream of dam. Analysis result of the sandbar area was decreased 17 %. Sandbar area was 38 % of the channel areas at the pre dam, but 21 % at the post dam. Alteration indies of the sandbar were $-0.9921{sim}2.9528$. Analysis result of the vegetation area was increased 13 %. Vegetation area was 11 % of the channel areas at the pre dam, but 24 % at the post dam. Alteration indies of the vegetation were $-0.8908{sim}12.0736$. Temporal variation of the sandbar and vegetation were analyized at the An Dong dam, Im Ha dam, Hap Chun dam. Analysis result of the sandbar was decreased $42,600m^2$ per year, but vegetation was increased $51,700m^2$ per year. Sandbar area was decreasing more fast than vegetation area increasing. |
