Experimental Modeling of Wave Forces and Hydrodynamics on Elevated Coastal Structures Subject to Waves, Surge or Tsunamis: The Effect of Breaking, Shielding and Debris

Abstract

Coastal communities provide important economic, transport, and recreational services to large numbers of people worldwide. However, these coastal communities are vulnerable to damage by extreme events such as tropical cyclones or tsunamis. Waves and surge, as well as tsunami-wave events, may cause extensive damage to elevated structures through a combination of horizontal and vertical wave and surge-induced forces. Structural elevation has been shown to be a critical variable affecting damage and loss. Recent efforts have been made to retrofit structures or improve coastal protection and damage mitigation plans in coastal communities to increase community resilience. However, to effectively retrofit old structures or design new structures to resist damage due to hurricanes or tsunamis, engineers require an accurate estimation of both the wave hydrodynamics and the resulting loads.

Building Resilient Coastal Communities: The NHERI Experimental Facility for Surge, Wave, and Tsunami Hazards

“…Subsequent to the testing phase, the HWRL EF leadership organized a series of monthly teleconferences with the UW team to assist with the subsequent data analysis and publication phase. To date, the project has led to the publication of 3 peer-reviewed journal papers (all co-authored with UW and OSU teams) and 1 conference proceedings (Lomonaco et al, 2018;Alam et al, 2020;Shekhar et al, 2020;Winter et al, 2020). Significantly, the project led to the successful submission of the project, NSF-1933184 "Understanding and Quantifying Structural Loading from Tsunami-Induced Debris Fields" funded to the UW team.…”

Assessing flooding impact to riverine bridges: an integrated analysis

“…On the contrary, literature about modeling the hydrodynamic forces of the fluid on bridges due to riverine floods is limited, especially concerning fragility models or reliability analysis (Pregnolato, 2019;Gidaris et al, 2017). Existing research investigated tsunami impact to bridges (e.g., Motley et al, 2016;Lomonaco et al, 2018;Qin et al, 2018;Winter et al, 2017), where computational fluid dynamics (CFD) techniques are used to compute hydrodynamic forces on bridges and components. Li et al (2021) advanced a CFDbased numerical study on the tsunami-induced scour around bridge piers.…”

An integrated impact analysis for riverine bridges subjected to high river flows

“…There is some research dedicated to tsunami impact to bridges (Motley and al., 2015;Lomonaco et al 2018;Qin et al, 2016;Winter et al, 2017), where computational fluid dynamics (CFD) techniques are used to compute hydrodynamic forces on bridges and components. Also, Kerenyi et al (2009) applying CFD to compute hydrodynamic forces on inundated bridge decks, however the analysis is limited to the An integrated impact analysis for riverine bridges subjected to high river flows M. Pregnolato, P. Bates ABSTRACT: Flood events are the most frequent cause of damage to infrastructure compared to any other natural hazard, and global changes (climate, socio-economic, technological) are likely to increase this damage.…”
