Abstract

This paper aims to introduce the application of GIS techniques integrating mathematical functions to estimate the loss of human life caused by floods in Tuy Phuoc district, Binh Dinh province. From there, it helps local authorities propose measures to prioritise rescue and relief for people when floods occur. The calculation results of this paper, according to the historical flood scenario in 2013 with flood frequency P = 2%, show that in the Tuy Phuoc district, the flood risk index is very high, concentrated in communes located in the South East of the district such as Phuoc Hoa, Phuoc Son, Phuoc Thuan communes where the terrain is low and borders the Thi Nai lagoon. On the contrary, the low-risk areas of Phuoc Thanh, Phuoc Hung and Phuoc Quang communes are located northwest of the district with relatively higher terrain. The accuracy of the calculation results estimates that human damage due to flooding is about 70%.
