Phase1: Bed shear stress measurements at 0.3m offshore of still water line, with water depth 2.1m, with generation of various long waves offshore
|
DOI:10.4231/D3NS0KX60
Experiment Type: Tsunami Wave Basin
Description: This experiment is part of a series of experiments that investigates the role of the bed shear stress and near-bed flow to understand how offshore wave characteristics may correlate with onshore sediment transport. A new design of instrument for direct measurement of the bed shear stress has been developed and is deployed here in the submerged region below the still water line. The leading tsunami waveform is modelled as several different types of long waves including the solitary wave, a solitary bore, and leading depression N-waves. Varying wave amplitudes of these waves are tested.
NB: Location 1 is the most onshore location on the test platform. The test platform is installed between bays 15 and 16. Trials 4-12 - Solitary Waves. Trials 13-21 - Bores. Trials 22-25 - Double Solitary Waves. Trials 26-33 - LDN Waves. Trials 1-3 have bad ultra sonic wave gauge data since the sensor was too close and the waves rose above the sensor.
