Đánh giá ảnh hưởng của biến đổi khí hậu đến an toàn hồ chứa nước đá bàn tỉnh Bình Định

Abstract

Vietnam currently has a lot of reservoirs of all kinds, supplying water to agriculture, industry and other sectors. Most of the reservoirs were built during Vietnam wars with low standard, low fund and simple technology, therefore the safety of such reservoir dams was not that high. Under the strong impact of climate change, safety risks of dams are increasingly becoming a cause for public concern. In this study, the impact of climate change on the safety of the Da Ban reservoir in Binh Dinh province was analyzed and assessed in terms of flood criteria. The results show that under the climate change condition, the height of the dam should be increased by 7% to 10% compared with the originally designed dam height.
