A sensitivity analysis of the bottom-up algorithm for the segmentation of H_s-time series

摘要

This paper deals with the effect of the maximum allowed error (MAE) on the segmentation of significant wave height time series using the bottom up approach. This approach was implemented in Soukissian, Samalekos (2006), who adopted a constant MAE in order to identify and analyze the developing, decaying and stationary H_s -sea states andrntheir associated durations. The MAE corresponds to the representation error (obtained from the method of least squares) and determines the length of each segment (i.e., the sea state duration) and the overall quality of the linear fit. Different values of the MAE provide different populations of developing, decaying and stationary sea states and associated durations. In this paper a detailed sensitivity analysis of the effect of the MAE on the duration and intensity statistics of the obtained sea states is made.
