Query: A survey on tidal analysis and forecasting methods for Tsunami detection   Accurate analysis and forecasting of tidal level are very important tasks for
human activities in oceanic and coastal areas. They can be crucial in
catastrophic situations like occurrences of Tsunamis in order to provide a
rapid alerting to the human population involved and to save lives. Conventional
tidal forecasting methods are based on harmonic analysis using the least
squares method to determine harmonic parameters. However, a large number of
parameters and long-term measured data are required for precise tidal level
predictions with harmonic analysis. Furthermore, traditional harmonic methods
rely on models based on the analysis of astronomical components and they can be
inadequate when the contribution of non-astronomical components, such as the
weather, is significant. Other alternative approaches have been developed in
the literature in order to deal with these situations and provide predictions
with the desired accuracy, with respect also to the length of the available
tidal record. These methods include standard high or band pass filtering
techniques, although the relatively deterministic character and large amplitude
of tidal signals make special techniques, like artificial neural networks and
wavelets transform analysis methods, more effective. This paper is intended to
provide the communities of both researchers and practitioners with a broadly
applicable, up to date coverage of tidal analysis and forecasting methodologies
that have proven to be successful in a variety of circumstances, and that hold
particular promise for success in the future. Classical and novel methods are
reviewed in a systematic and consistent way, outlining their main concepts and
components, similarities and differences, advantages and disadvantages.
