STATISTICAL CHARACTERISTICS OF OFFSHORE CURRENTS

Michel K. Ochi

Abstract


This paper presents the analytical derivation of probability density functions applicable for tidal (high frequency components), residual (low frequency components), and total (the vector sum of tidal and residual) current velocities. The theoretical probability density functions are compared with histograms constructed from measured data. A method to estimate the extreme current velocities in a specified time period is presented by applying extreme value statistics.
