APPLICATION OF GEOTECHNICAL BAGS IN PROTECTING RIVERBANKS IN THE MEKONG RIVER DELTA

Abstract

Riverbank erosion in the Mekong Delta is occurring seriously, affecting people's lives and the socio-economic development of the region. This article describes the process of designing, piloting, and monitoring of displacement for a model of bank protection solution using D-Box geotextile bags on rivers and canals in the fields (level III, IV rivers). The pilot model was implemented on the Long Xuyen - Rach Gia River in Thoai Son district, An Giang province, showing that the solution effectively protects the banks, creates natural landscapes and is supported by local people. The monitoring results recorded consistent displacement along the length of the embankment, with the largest displacement being 10 cm and the smallest being 4 cm towards the river - well within the allowable range. The solution can be widely applied in areas with similar conditions. It is necessary to develop a technical process to guide construction so that people and authorities can easily implement construction.
