Rheological and plate’s hydrodynamic resistance in fluid mud measurements for the nautical bottom applications: An experimental study for sailing through fluid mud applications

When a ship reaches the shore, the water depth reduces and thus the under-keel clearance also reduces. The ship keel clearance influences the maneuverability of the sailing ship.<br/><br/>In this thesis project, the link between the fluid mud rheology and its density is first investigated. The exponential relation reformulated between the...

On the Historical Development of the Mathematical Theory of Water Waves

HIstorical overview of the development of wave formulas used in coastal engineering.

The design of upright breakwaters

The historical development of upright breakwaters in Japan is briefly reviewed as an introduction. Various wave pressure formulas for vertical walls are discussed, and then the design formulas currently employed in Japan are presented with an example of calculation. Several design factors are also discussed.

Laboratory investigation on the overtopping rate of seawalls by irregular waves

Series of measurements with irregular waves were undertaken for model seawalls of vertical walls with and without protection by concrete block mounds. Experimental data were compared and supplemented with theoretical calculations by the combination of the author's random wave breaking model in shallow waters and the weir type overflow model. The...

Measurement of hydrodynamic pressures on two-dimensional ship models heaving and rolling with large amplitudes

Experimental determination of bending moments for T2-SE-A1 tanker model in regular wave
