IMPACT OF URBANIZATION ON FLOODING IN KHANH HOA PROVINCE

Tóm tắt

Currently, natural disasters such as floods and inundation are increasing both in the quantity and degree of impact. The areas most heavily affected by flooding are low-lying areas such as coastal cities and countries. The characteristics of natural disasters such as floods and inundation are not only affected by changes in climate factors but also by urbanization and human activities. This paper uses the MIKE FLOOD (DHI) model to analyze the impact of urbanization on flood and inundation characteristics in the downstream areas of Cai river in Khanh Hoa province. The results show that the change of urban topography during the urbanization period has significant effects on the floodplain areas in terms of location and intensity, thereby changing the characteristics of flood and inundation distribution spatially.
