Using AHP-PROMOTHEE for Selection of Best Low-Impact Development Designs for Urban Flood Mitigation
نویسندگان
چکیده
This work first studies the effects of several Low Impact development methods on urban flood control. The Analytic Hierarchy Process-Preference Ranking Organization Method for Enrichment Evaluation (AHP-PROMETHEE) combination method is then used to select best design. A drainage system in Golestan town Semnan under a 5-year return period investigated as case study. LID are selected based region's conditions and facilities. Then Rain Barrel (RB), Permeable Pavement (PP), Infiltration Trench (IT) were considered methods. RB, PP, IT, IT-PP, IT-RB, PP-RB, IT-PP-RB usage scenarios. Four analytical ranking criteria, implementation cost, hydraulic performance, environmental impact during implementation, ease chosen procedure. Also, weight these criteria was obtained using Process (AHP). Finally, after determining designs ranked Preference (PROMETHEE) method. results demonstrate effectiveness PP-RB scenario with an average reduction 90% peak discharge 80% total volume. It also observed that weakest performance related IT scenario, decrease 60% flow 47% AHP-PROMETHEE analysis showed simultaneous use RB coverage percentage 5% cost $ 57,710 reduced volume by 51.54% 48.8% compared current system. According AHP-PROMETHEE, IT-RB-5 project proposed among 70 projects studied. study practical choosing from schemes
