  • Experimental study of counter-propagating solitary wave collisions

    Creator:
    Chen, Yongshuai
    Abstract:
    To better understand the extreme local amplification of tsunami, the experimental investigation on counter-propagating solitary wave collisions over a horizontal bottom was conducted using the optical measurement techniques: Particle Image Velocimetry (PIV), and Laser Induced Fluoresce (LIF). Head-on collisions and oblique collisions of equal-amplitude as well as unequal-amplitude waves were...

  • Analysis of pressure variations observed at the ocean bottom during the 2003 Tokachi-Oki earthquake

    Creator:
    Li, Wenwen
    Abstract:
    Most tsunami studies have been conducted based on the incompressible fluid theory. However water compressibility must be considered for the process of tsunami generation by bottom displacements during submarine earthquakes. During the 2003 Tokachi-Oki earthquake, the ocean-bottom pressure variations were registered by the pressure gauges PG1 and PG2 located right...

  • Flow visualization for wake formation under solitary wave flow

    Creator:
    Seiffert, Betsy Rose
    Abstract:
    The use of data extracted from particle image velocimetry (PIV) along with vector and tensor visualization techniques provides a valuable tool for understanding a complex flow field. By studying a simple geometric structure such as a cylinder under a simple transient waveform, fundamental mechanisms of wake development under solitary wave...

  • Amplification of solitary waves along a vertical wall

    Creator:
    Li, Wenwen
    Abstract:
    Reflection of an obliquely incident solitary wave at a vertical wall is studied experimentally in the laboratory wave tank. Precision measurements of water-surface variations are achieved with the aid of laser-induced fluorescent (LIF) technique and detailed temporal and spatial features of the Mach reflection are captured. During the development stage...

  • Review of guidelines for the design of tsunami vertical evacuation buildings

    Creator:
    Cawley, Jessica Grace
    Abstract:
    Tsunamis have the potential to inflict severe damage and loss of life in coastal communities. Structures known as vertical evacuation buildings provide an alternative evacuation site for communities living in relatively flat, coastal regions with inadequate sources of high ground for evacuation. Design of these structures balances risk and economy,...
