Development of a Probabilistic Framework for Debris Transport and Hazard Assessment in Tsunami-Like Flow Conditions
Publisher: ASCE
Abstract: In the past, hydraulic and structural design has predominantly relied on deterministic methods, often neglecting the stochastic nature that underlies transient loading processes. Nowadays, probabilistic design methods have ...
Nonhydrostatic Numerical Modeling of Fixed and Mobile Barred Beaches: Limitations of Depth-Averaged Wave Resolving Models around Sandbars
Publisher: ASCE
Abstract: Along sandy coastlines, submerged, shore-parallel sandbars play an essential role in shoreline morphology by dissipating wave energy through depth-induced wave breaking. While wave breaking and sediment transport around ...
Ecohydraulics of Surrogate Salt Marshes for Coastal Protection: Wave–Vegetation Interaction and Related Hydrodynamics on Vegetated Foreshores at Sea Dikes
Publisher: ASCE
Abstract: Vegetation on foreshores in close vicinity to sea dikes may prove beneficial as regulating ecosystem service in the context of coastal defense, dike safety, and flood protection by reducing loads on these defense structures. ...
Probabilistic Investigation and Risk Assessment of Debris Transport in Extreme Hydrodynamic Conditions
Publisher: American Society of Civil Engineers
Abstract: Recent extreme hydrodynamic events, such as the 2004 Indian Ocean Tsunami, 2005 Hurricane Katrina, and 2013 Typhoon Haiyan, have indicated the vulnerability of coastal communities. As a result, emphasis has been placed on ...
Multiple Debris Impact Loads in Extreme Hydrodynamic Conditions
Publisher: ASCE
Abstract: Video footage from the 2004 Indian Ocean and 2011 Tohoku tsunamis showed large quantities of debris entrained within the inundating flows. Such extreme debris conditions can lead to a high probability for multiple impacts ...
Experimental Investigation of Loading due to Debris Dams on Structures
Publisher: ASCE
Abstract: The entrainment of debris in tsunami-induced floods and storm surges can result in their accumulation on structures, a phenomenon known as debris damming. Such dams can decrease the stability of the affected structures by ...
Experimental Investigations of Debris Dynamics over a Horizontal Plane
Publisher: American Society of Civil Engineers
Hydrodynamics and Associated Scour around a Free-Standing Structure Due to Turbulent Bores
Publisher: ASCE
Abstract: Forensic engineering field surveys conducted in the aftermath of large-scale tsunamis documented the presence of deep local scour holes around structures caused by extreme inundation occurring during such events. The ...
Engineering Lessons from September 28, 2018 Indonesian Tsunami: Scouring Mechanisms and Effects on Infrastructure
Publisher: ASCE
Abstract: The September 28, 2018 earthquake and tsunami, which occurred north of Palu City, Indonesia, attracted widespread interest from the scientific community due to the unusually large tsunami that occurred after a strike-slip ...
Spatiotemporal Scouring Processes around a Square Column on a Sloped Beach Induced by Tsunami Bores
Publisher: ASCE
Abstract: Tsunamis continue to pose an existential threat to life and infrastructure in many coastal areas around the world. One of the risks associated with tsunamis is the formation of deep scour holes around critical infrastructure ...
