Title
Analysis of Runoff Reduction Efficiency and Characteristic for Test-bed of Low Impact Development Techniques on Sidewalk : for Permeable Block, Vertical Infiltration Pipe, Storage Tank
이대희 Daehee Lee
Abstract
The purpose of this study is to analyze the characteristics of Low Impact Development(LID) techniques in LID test-bed and to analyze runoff reduction efficiency of that techniques. The K research institute with a test-bed for LID technique was selected as a study area and a stormwater management target was set to manage water quality and quantity of runoff. The Permeable Block, Vertical Infiltration Pipe(VIP) and Storage Tank were selected and their characteristics were analyzed. Eight scenarios were created from the selected LID facilities and SWMM-LID runoff simulation was carried out. The optimization method of the LID techniques is suggested by analyzing the stormwater runoff characteristics for each scenario. As a result of SWMM-LID runoff simulations, the peak flow was reduced by up to 64.4 % and the total runoff was reduced by up to 35.2 %. In addition, it is effective to apply the permeable block and VIP to the area where the ratio of sidewalk is large, and it is considered that the application of the storage tank is effective in reducing the runoff in the area where the ratio of sidewalk is small.
