This test studies the impact of the 1976 storm surge on the Dutch coast at Holland. The surge during the 1976 storm was the highest since the 1953 storm. In the night between January 2nd and 3rd wind speeds reached a maximum near the Dutch coast. In the central and eastern parts of the North Sea the wind speed reached 51 m/s from the Northwest. The strongest gale on the Dutch mainland was recorded at Vlissingen: southwestern wind with a speed of 26 m/s. This caused a significant storm surge with a maximum water level in the afternoon of January 3rd \citep{VanDerWerf2011}.

Between October 1975 (pre-storm) and February (post-storm) 1976 30 cross-shore profile measurements were performed at eight locations (among others) along the North-Holland coast. The observed profiles generally extend from the low water line to above the dune foot (+3 m NAP). We have extended these with the latest JARKUS data (yearly profile measurement from approximately -8 m NAP to the first dune row), measured in spring 1975. 1D XBeach models were setup for these 30 transects, of which 3 are used in this test.

As an example, \autoref{fig:1976_random_profile} shows the initial cross-shore profile with the pre-storm measurement, the post-storm measurement and the final profile predicted by XBeach for one of the 30 transects. \autoref{fig:1976_storm_surge_bss} shows the Brier Skill Score of all computed transects.
