Development of Ecological Scour Protection Technique with Non-toxic Materials and Examination of Field Application
Hong-Kyu Ahn, Sang-Hoon Lee, and Min-Kyu Ji
Abstract—In the river-crossing structures such as weirs and drop structures, an apron is to be facilitated to prevent the scour of the structure from overflow. Also, to prevent the scour of the apron on the down-stream, riprap is laid to stop the scour and to protect the riverbed, but as time passes, there are problems of movement or loss due to the flood, therefore, it ultimately effects on the safety of the river-crossing structure.
In this study, non-toxic material was used to develop the eco-friendly, multi-layered porous bed protection technology on the weir down-stream, and the developed bed protection technology was reviewed with mathematical safety through the CFD 3D numerical analysis and indoor test. Also, the developed technology was demonstrated in partial down-stream sections of the Daecheongcheon Stream in Gimhae, and in each stages of before, middle and after the construction of the pilot project, the field applicability of the developed technology was verified through physical, chemical and biological monitoring.
Index Terms—River restoration, non-toxic material, bed protection technology, monitoring.
