Abstract

In the general field of flood risk management an important part is the hazard conditions related to vehicular and pedestrian circulation. Our cities are formed by several components which are exposed to floods of a magnitude according to the importance of the rainfall event and the design of the urban drainage system. The knowledge of the hazard level affecting on each component is crucial for an adequate flood risk management in urban areas. Vehicles are essential components of our cities, so it is clear the importance to analyse the vehicle stability during flooding episodes in urban areas. The vehicles instability in case of floods can generate tangible direct damages due to the physical contact of water with them, but also indirect tangible damages due to traffic disruption. Moreover, after stability losing, the vehicle becomes buoyant and it is washed away colliding with urban elements with potential situations of injuries and fatalities (intangible damage). In this way, vehicles might be considered as massive debris which are washed away by the flood and could represent significant economic damages and compromising pedestrian safety. Therefore, the analysis of the stability of vehicles exposed to flooding is crucial in order to make decisions to reduce the damages and hazards. After a comprehensive experimental campaign with scaled vehicles models, a new experiments-based methodology to obtain the stability threshold for any real vehicle exposed to flooding is proposed. This methodology enables to define a stable area in the domain flow depth-velocity with sufficient accuracy for any real vehicle. Moreover, three-dimensional simulations were conducted in order to understand more deeply the instability phenomena and validate the obtained experimental stability thresholds through non-tested hydraulic conditions (i.e. higher flow velocities). Furthermore, a review of the state-of-the-art regarding damage functions for vehicles was conducted. The level of completeness and accuracy of the approaches for the damage curves founded are quite different, being selected as the most accurate the USACE proposal. USACE’s development is the most current research and all the steps for the development of the damage curves are comprehensively described. These results have been implemented in Badalona case study, in the framework of the BINGO EU project, thereby assessing both hazards due to vehicles instabilities and direct damages due to physical contact of water with stable vehicles by employing existing damage curves for vehicles.

Bio

Dr Eduardo Martínez-Gomariz is a Spanish Civil Engineer who has developed his entire professional career in Spanish consultancy firms related to hydraulic and hydrologic projects since 2004. Eduardo complemented his background obtaining the degrees of MSc in Civil Engineering, Master in Creation and Management of innovative technology-based firms and a PhD in Civil Engineering.

From 2012 to 2016 Eduardo was a member of the Flumen Research Institute, within the Technical University of Catalonia, which is located in Barcelona (Spain), where he obtained the degree of PhD in 2016. His PhD research was focussed on urban flood risk management, namely experimental and numerical analysis of stability for pedestrians and vehicles when exposed to flooding. Currently he holds the position of R&D Project Manager at CETaqua (SUEZ group), involved in the management and development of some water-related EU funded projects, such as PEARL, BINGO and RESCCUE.
