Integrating urban flood models can offer more comprehensive solutions for urban waterlogging problems. The tightly coupled approaches adopted in existing integrated models are self-enclosed. When modelers try to integrate models, considerable effort is required to rewrite codes and build the new coupled model. To help modelers reuse urban flood models and configure different coupled solutions, we propose a component-based method. The model components were built to achieve the reuse of models based on the Basic Model Interface (BMI). The bidirectional coupled approach was designed to support the interchange of water. Moreover, a model interaction hub was developed to configure different coupling work. An integrated modeling framework for urban flood simulation was thus constructed. The Storm Water Management Model (SWMM), ANUGA, and LISFLOOD-FP were employed to demonstrate the capabilities of this framework through experiments involving two integrated solutions. The results show that the proposed integrated modeling framework can provide a reusable solution for urban stormwater simulation. Ausführliche Beschreibung
