In recent years, many kilometres of the Cửa Đại Beach have suffered from severe erosion due to rising sea levels and a shortage of muddy sand flowing from the upstream Thu Bồn River, affecting the livelihood of local residents as well other socio-economic activities in the area.
Previous reports by Việt Nam News showed that the shortage of muddy sand was caused by construction of hydropower plants and sand over-exploitation on the Thu Bồn River.
The event focussed on solutions, ideas and experiences in applying science and technology in water works related to estuaries, coasts and rivers, especially as climate change is exerting serious impacts on many localities across Việt Nam.
In the short-term, the provincial People’s Committee agreed with the proposed scheme of artificial beach nourishment to save the beach from erosion provided that future projects ensure sustainability, and closely follow set planning.
Besides in-house discussions, participants carried out field trips to survey and record the situation at Cửa Đại Beach.
According to the Water Resources Directorate, erosion at estuaries and coasts in the central region is proceding at an alarming rate and is increasingly worrying.
In the last two years, 164 erosion spots measuring 170km were found along the 900km coastline from Quảng Trị to Phú Yên provinces, Vietnam Television (VTV) reported on Monday.
The Cửa Đại Beach area in Hội An City witnesses sea encroachment of 50-200m annually. Erosion is likely to occur at nearby beaches, such as Hà My Beach in Điện Bàn Town and Đà Nẵng City’s beaches.
The two-day workshop is jointly held by Quảng Nam Province’s People’s Committee, Central Region College of Technology–Economics and Water Resources, Water Resources University, and Hồ Chí Minh City University of Technology in conjunction with Japan’s Tohoku University.
Over the past 20 years, the international workshops on "estuaries, coasts and rivers” have been held in numerous countries including Japan, India, Indonesia, Thailand and Việt Nam. —VNS
