Resumen
The present work introduces an analysis of the measurement and model effects that exist in monopile scour protection experiments with repeated small scale tests. The damage erosion is calculated using the three dimensional global damage number ??3??
S

D
and subarea damage number ??3??,??

. Results show that the standard deviation of the global damage number ??(??3??)=0.257
s

and is approximately 20% of the mean ??3??

. The irreproducible maximum wave height, chaotic flow field and non-repeatable armour layer construction are regarded as the main reasons for the occurrence of strong model effects. The measurement effects are limited to ??(??3??)=0.039
