Narrow Results

Results of a long-term wave measurement campaign in a large, shallow lake (Lake Ussel) in the Netherlands are described. Model validation is one of the main applications of the data. Therefore, the data are extensively compared with results of the SWAN wave model, which is used to evaluate dike design conditions. Wave heights were well predicted by SWAN except in some complex situations. Wave periods were generally underestimated. Finally, there was significant natural scatter in the experimental data. Therefore, model validation should not be based on case studies only. Rather, one should use large data sets for global model validation and case studies for in-detail investigations.
