Infiltration trenches for highway drainage

Flood control facilities such as permeable pavements and infiltration trenches must be installed in Japan as stipulated by law when a new road over 1000 square metres is developed in designated urban river basins. To find out the basic flood control performance of infiltration trenches, and to investigate the influence area of seepage water, infiltration tests for a real-size trench, and runoff calculations under normal trench condition were carried out. From the experimental results, it was confirmed that the capacity of infiltration trenches were evaluated accurately by the formula developed by the Association of Rainwater Storage and Infiltration Technology in 1995, and that the saturation region from the trench was almost the same regardless of the soil type. From the runoff calculation results, the relationship between soil permeability and runoff control performance was confirmed.
