Coastal and estuarine morphology changes induced by the 2011 great east japan earthquake tsunami
Hitoshi Tanaka,Nguyen Xuan Tinh,Makoto Umeda,Ryutaro Hirao,Eko Pradjoko,Akira Mano,Keiko Udo +6 more
TL;DR: The 2011 Great East Japan Earthquake that occurred on March 11, 2011, had magnitude of 9.0 on the Richter Scale with the epicenter approximately 70 km east of the Oshika Peninsula in Miyagi Prefect...
Journal ArticleDOI
Impact of the 2011 tohoku earthquake and tsunami on beach morphology along the northern sendai coast
TL;DR: In this paper, the authors investigated the extensive changes in extensive changes caused by the 2011 Tohoku Earthquake and Tsunami off the Pacific Coast of Miyagi Prefecture, Japan.
Journal ArticleDOI
Characteristics of turbulent boundary layers over a rough bed under saw-tooth waves and its application to sediment transport
TL;DR: Watanabe et al. as mentioned in this paper proposed a new calculation method for bottom shear stress based on velocity and acceleration terms, theoretical phase difference, φ and the acceleration coefficient, expressing the wave skew-ness effect for saw-tooth waves.
Journal ArticleDOI
Full-range equation of friction coefficient and phase difference in a wave-current boundary layer
Hitoshi Tanaka,Aung Thu +1 more
TL;DR: In this article, approximate formulae of wave-current friction coefficient and phase difference, spanning all flow regimes, are obtained based upon the theoretical results of Tanaka and Shuto (1981).
Journal ArticleDOI
Friction Coefficient for a Wave-Current Coexistent System
Hitoshi Tanaka,Nobuo Shuto +1 more
TL;DR: In this paper, a friction coefficient f cw is derived for a wave-current coexistent system, by assuming a time-invariant eddy viscosity, which is a function of four parameters, Zn/Z0, ǫ/uw, ϕ and ϕ/ǫ.
