Nghiên cứu ảnh hưởng của việc xây dựng kè chống sạt lở khu du lịch sinh thái Nam Ô theo phương án quy hoạch tới khả năng thoát lũ của sông Cu Đê, thành phố Đà Nẵng

Abstract

Cu De is the second largest river in the city of Da Nang flowing into Da Nang Bay. According to the planning, the Nam O eco-tourism area and Cu De river are adjacent on the right riverbank, which leads to necessary to build an embankment for bank protection. The planning stage, however, only has been determined the location of the route preliminarily so it requires studying, calculating, and verifying whether the planned embankment layout is suitable for reality to serve the adjustment process. The study has shown the planned embankment location has encroached on the Cu De river resulting in an effect on the flood drainage possibility. It will increase the water level from 0.43 to 0.59 meters with a 10% frequency flood, from 0.43 to 0.64 meters with a 5% frequency flood compared to the current situation
