Abstract

The purpose of this study is to establish the management standards of water systems in Korea. The damage factors of the water systems were classified by accumulation, adsorption, and abrasion. According to the thickness of volcanic ash, the management stage of the water systems was derived in four steps; VAD (Volcanic Ash Degree) I (0~1 mm), II (1~3 mm), III (3~5 mm), IV (over 5 mm). Finally, the management standards for water systems which consist of alarm levels, impacts of volcanic ashes, procedures and action plan to deal with the damage, are presented.

백두산 분화시 북풍 또는 북동풍이 발달하게 되면 국내에 화산재가 확산될 가능성이 있으며, 화산재에 의해 민감한 영향을 받는 상수도 시설의 관리기준이 필요하다. 본 연구에서는 국내 상수도 시설의 관리 기준 수립을 위해 국외의 다양한 화산에 대해 분야별 피해사례를 조사하였으며, 이를 바탕으로 상수도 시설의 피해 요인을 퇴적, 흡착/침착, 마모로 나누어 예상되는 피해 정도를 유형화하였다. 또한 위험평가 결과를 바탕으로 화산재 퇴적 두께에 따라 상수도 시설의 관리 단계를 4단계로 도출하였으며, 0~1 mm은 VAD(Volcanic Ash Degree) I, 1~3 mm는 VAD II, 3~5 mm는 VAD III, 5 mm 이상은 VAD IV로 제시하였다. 최종적으로 도출된 관리 단계별 경보 기준, 화산재 영향, 피해 대응 절차 및 방안 등으로 구성된 상수도 시설 관리 기준(안)을 제시하였다.
