abstract = "The prediction of tidal currents in the coastal region
on a real-time or online basis is useful in taking
operation- and planning-related decisions such as
towing of vessels and monitoring of oil slick
movements. Currently, however, this is done in offline
mode on the basis of the statistical method of harmonic
analysis involving fitting of harmonic functions to
measured data. Alternatively, numerical solutions of
hydrodynamic models can also provide spatial and
temporal information on currents. Owing to the complex
real sea conditions, such methods may not always yield
satisfactory results. This paper discusses a few
alternative approaches based on the soft computing
tools of artificial neural networks (ANNs) and genetic
programming (GP), as well as the hard mathematical
approaches of stochastic and statistical methods. The
suggested schemes use only a univariate time series of
currents to forecast their future values. The
measurements of coastal currents made at two locations
in the Gulf of Khambhat along the west coast of India
have been analysed. The current predictions over a time
step of 20 min, a few hours, and a day at the specified
locations were carried out. It was found that the soft
computing schemes of GP and ANN performed better than
the traditional hard technique of harmonic analysis in
the present application. This work should initiate more
application of GP in coastal engineering. Addressing
the problem of current predictions in real-time mode
based on analysis of observed time series of ocean
currents is a specialty of this work.",
