Opis (eng)

This paper examines the impact of climate change on underground traffic tunnel infrastructure, specifically focusing on the increased pluvial flooding risk associated with changing precipitation patterns and extreme weather events. We are presenting a 2D hydrodynamic model designed to assess and enhance the flood resilience of these tunnels during torrential events. The case study conducted in Belgrade, Serbia, evaluates the effectiveness of proposed flood risk management techniques aimed at safeguarding the city’s underground transportation infrastructure from potential flooding. Using the Direct Rainfall Method (DRM), our model simulates rainfall events with various return periods (e.g., 10, 100, and 500 years) to provide a comprehensive assessment of flood impacts on tunnel infrastructure. Detailed topographical data is utilized to accurately capture the complex geometry of the tunnel system and its urban context, allowing for a thorough investigation of factors such as tunnel portal design, raising entrance to the tunnel, drainage system capacity, surface runoff management, and the implications for traffic flow and emergency response. The simulations reveal critical insights into water levels, discharge, and inundation zones under differing rainfall scenarios. The findings underscore the necessity for resilient design strategies, including road design adaptations (elevation adjustments), construction of flood barriers, implementation of effective water management systems, and sustainable drainage solutions. Furthermore, future considerations regarding these issues are focused on the integration of green construction practices and energy-efficient designs as strategies to enhance the resilience of tunnel infrastructure in response to climate-related challenges. By delineating flood-prone areas and proposing targeted drainage improvements, this research contributes to developing effective flood risk management plans. Ultimately, this study emphasizes the importance of integrated and systemic approach that merges planning strategies and structural improvements to bolster the safety and resilience of the Belgrade underground transportation system, solving similar issues on tunnelling projects worldwide.
