Analysis on Appropriate Plants of Infiltration Swale for Road Runoff

Abstract

This study is to find appropriate plant for infiltration swale (which is natural LID infrastructure) and suggest basic research database for building infrastructure of LID facilities. Through the research inside, it first selects the plant strong to flooding and salt tolerance. Also, the research built infiltration swale along the road, planted those strong plants and monitored how well those plants adapted into the environment. Particularly, it showered 72mm/hr-speed artificial shower, also with natural shower, given that plants were vulnerable to flood because of influx of the rain. As a result of field applicability monitoring, Pennisetum alopecuroides and Equisetum hyemale (which degrade the pollutant well and adapt into rainy environment) are planting individually, or Juncus effusus var. decipiens, Liriope platyphylla, Miscanthus sinensis Andersson, Euonymus japonica (which are strong to rainy environment) and Pennisetum alopecuroides and Equisetum hyemale are mixed planting. The research should have monitored the plant for more than one year to study them, but the research only lasted five months. Therefore, it is hard to generalize. After all, through the long term research, it should pursue study more on appropriate plant materials and database that can be the reference for infrastructure establishment and maintenance.

Evaluation of Field Application of Soil Conditioner and Planting Chrysanthemum zawadskii on the Roadside Soils Damaged by Deicing Agents

“…There was also a study that selected plants suitable for LID infiltration trenchs including Juncus effusus var. decipiens, Phragmites communis, Equisetum hyemale, Iris sanguinea, Hemerocallis fulva, Iris pseudoacorus, Miscanthus sinensis, Pennisetum alopecuroides, and Liriope platyphylla (Lee et al, 2016).…”
