Although a number of river restoration techniques in consideration of flood control and ecology have been recently developed and applied to rivers, most of them do not properly reflect the domestic conditions. Besides, there is still insufficient technique available to control the adverse effects and cope with changes in river environment due to rapid climate change, such as increased rainfall and heavy rain while excessive use of concrete can cause extensive damage to the surrounding landscape and the river’s ecosystem. For those reasons, there is a high demand for ecologically sound river restoration techniques that can strengthen the hydraulic stability by effectively responding to climate change, achieved by utilizing non- or low-toxic materials that do not affect the river environment and the life cycle of living organisms, without releasing harmful substances into the river.

In this study, with non-toxic materials we developed a riverbank revetment technique enabling stable flood control and habitats of various organisms such as plants and fishes. The technique was tentatively applied to the upstream section of Gwangnyeocheon located in Masanhoewon-gu, Changwon after being tested for its hydraulic stability on actual sized waterways and then the field applicability of the technique was analyzed and verified through the physical, chemical and biological monitoring before, during, and after construction.
