Water Management Analysis Module 모형을 이용한 투수성포장시설의 설계 및 계획 매개변수 도출

This study presents a systematic framework to derive the best values of design and planning parameters for low impact development (LID) practices. LID was developed to rehabilitate the distorted hydrological cycle due to the rapid urbanization. This study uses Water Management Analysis Module (WMAM) to perform sensitivity analysis and multiple scenario analysis for LID design and planning parameters of Storm Water Management Model (SWMM). This procedure was applied to an urban watershed which have experienced rapid urbanization in recent years. As a result, the design and planning scenario derived by WMAM shows lower total flows and peak flow, and larger infiltration than arbitrary scenarios for LID design and planning parameters. In the future, economic analysis can be added for this application in the field.
