Investigations on Irregular Waves in Hydraulic Models
Coastal Engineering 1980, 1980 The first part of the paper deals with some aspects of wave generation by mechanical wave-generators, especially with hydraulic transfer functions for pusher movement of the paddle, and the influences of signal characteristics and analysis methods. In the second part, results of measurements of orbital velocities and pressures in irregular waves are ...

Irregular Wave Overtopping Rates
Coastal Engineering 1984, 1984 Methods for estimating wave overtopping of coastal structures are reviewed and compared with the very limited available data and with each other. The different methods yield results which can vary more than an order-of-magnitude. For vertical seawalls, the U. S.

MOORED SHIP RESPONSE IN IRREGULAR WAVES
Coastal Engineering Proceedings, 1982 The traditional concept of representing a "random" sea state by just a variance spectral density has been found to be insufficient for modelling the slow drift oscillations of large moored ships. This paper illustrates, through experimental investigations, the importance of including wave grouping as an additional design parameter.

Directional Irregular Wave Kinematics [PDF]
, 1998 Abstract : Coastal and ocean processes are heavily influenced by the kinematics of waves. In order to understand these processes, researchers place a variety of instruments in the sea in an attempt to measure the waves. These instruments all measure a small set of physical quantities at a small number of locations. The balance of the kinematics must be

Orbital Velocities in Irregular Waves
Coastal Engineering 1980, 1980 Experimental and theoretical study to determine the applicability of linear wave theory for the description of the velocity field in irregular waves. A comparison between theory and measurement was executed both in frequency and in time domain. In frequency domain by means of the experimentally and theoretically determined frequency response functions ...
