A Numerical Hindcast Model for Wave Spectra on Water Bodies with Irregular Shoreline Geometry. Report 2. Model Verification with Observed Wave Data.

摘要

The procedures used to verify a numerical model for wave generation in water bodies of arbitrary shape are described. The verification results for Lakes Erie, Ontario, and Superior are presented. Parameters included in the study include significant wave height and frequency at the spectral peak. Examples of hindcast and measured one-dimensional (frequency) spectra are given. The study indicates a capability of the model to hindcast significant wave height such as root-mean-square error of about 1.5 ft and to hindcast the period of peak frequency with a root-mean-square error of 1 sec. These errors include effects from both the wave model and the hindcast model used to estimate the windfield. (Author)
