Abstract
ABSTRACT Urban flooding caused by urbanization and climate change is a critical challenge for city infrastructures. Infiltration trenches are a green infrastructure system that collects and temporarily stores rainwater. In this study, the efficiency of 12 infiltration trenches in Kayseri province of Turkey was analyzed using InfoWorks ICM. These analyses are characterized by 5 different return periods and 4 different distributions of rainfall over time. The model was validated with a historical rainfall event and showed good results according to statistical validation methods. The study also provides alternative solutions by including the effect of different infiltration ratios and simulations of different infiltration trench designs. Infiltration trenches, which were appropriately located, reduced flood depth and initial flooding time even during high return periods. By analyzing multiple infiltration trenches together, testing different scenarios and combining field application and modeling, the study provides outputs that will help urban flood management applications.
