Journal of Marine Science and Engineering, 2023 In recent years, with global warming and frequent natural disasters, existing offshore bridges are facing the risk of extreme wave action. The research on disaster prevention and mitigation measures of the box-girder superstructure of offshore bridges ...

Coastal Engineering Proceedings, 1988 Experimental measurements of hydrodynamic forces on a cubic block near the bottom under solitary waves were carried out. Horizontal and vertical forces were recorded and instantaneous and averaged values of hydrodynamic coefficients CD, C,, and C,_ for different boundary conditions, gap between block and bottom, e, and two or three-dimensional flow ...

Coastal Engineering Proceedings, 1974 Water waves exert a force on a pipeline which is placed within the zone of wave influence. This force is made up of a periodic force which is composed of a drag and an inertial force, and a non-periodic second order force which acts upward. The coefficients of mass C and drag C as defined by the "Morison equation" were evaluated for many wave and depth

WAVE FORCES ON SUBMERGED OBJECTS
Coastal Engineering Proceedings, 1976 Limitations of the Morison equation for computing wave forces on small submerged structures have encouraged the use of dimensionless relationships containing only height, period and water depth. However in dividing the force by the theoretical drag force or inertia force a relationship can be found with the Keulegan parameter (U. T/D) over a wide range

THE EFFECT OF WAVE CRESTS ON WAVE FORCES
Coastal Engineering Proceedings, 1968 This paper deals with wave forces from short crested waves as compared with two dimensional waves. The investigation comprised measurements of wind wave forces on fixed pontoons in a model, and a comparison of wave crest characteristics of wind waves in model and prototype. The model tests showed that the wave crests have a marked influence on the wave

Predictive value of P wave terminal force in lead V1 for atrial fibrillation: A meta‐analysis
Annals of Noninvasive Electrocardiology, 2020 Several studies have explored the association between P wave terminal force in lead V1 (PTFV1) and risk of atrial fibrillation (AF) occurrence, but the results were controversial.

An Experimental Investigation of Wave Forces on a Submerged Horizontal Plate over a Simple Slope
Journal of Marine Science and Engineering, 2020 We experimentally investigated the forces induced by monochromatic and solitary waves on a submerged horizontal plate in a wave flume. The experimental results of two-dimensional wave forces on the plate over a 1:10 simple slope and a flat bottom are ...

Wave Forces on Square Caissons
Coastal Engineering 1976, 1976 The forces and overturning moments exerted by waves on large vertical square-section caissons have been measured in the laboratory. Each model caisson extended from the bottom of a wave flume through the water surface and was oriented either with one side perpendicular to the direction of wave propagation or turned through an angle of forty-five ...
