内容記述 |
In recent years, especially after typhoon Morakot, extreme torrential rain has resulted in large amounts of landslides. The debris that accumulated downslope blocks the drainage way and easily induces debris flow. The large amount of debris transported to wild creeks downstream may caused elevated riverbeds and channel siltation. All nearby villages and utilities are under this threat. The cleanout work of aggregated debris is of great priority after a disaster. The cleanout of the debris can help the natural drainage system to recover its capability, and the recovered material can be effectively reused. Low-lying lands that were eroded in the past can be filled and protection measures can be applied, so as to raise the level of safety. Feasible methods to improve the engineering properties of the material can be applied for the purpose of ground modification. A certain percentage of cement can be added to the debris in situ to form a new material, which can then be applied in many situations, such as improving the durability of road beds, protecting river banks from erosion, and promoting foundation properties, etc. Every wild creek cleanout plan should include the amount of material that needs to be removed, the area where it is to be applied, and the engineering procedures required to adjust its properties. The cleanout work for wild creeks can help prevent future flooding and debris flow problems. This important remedial work that should be performed whenever needed or every year before the rainy season, and it should also be arranged as a part of the routine maintenance work carried out by the watershed’s management. Instead of using sabo dams, cleanout work for blocked wild creeks is a new treatment of the debris problem. Standard procedures for cleanout plans, including the above-mentioned details, should be set as soon as possible. |
