This section was located in between 10.5 and 14m downstream of the outflow opening of the overtopping simulator and subjected to irregular waves to be used in the validationof an erosion relation;False;False;True;False;False;False;2022-02-07 15:53:00;2022-02-07 15:54:00;;;;Other;139735.0;226778.0;;Test was performed at a distance of 10.5 to 14m from the overtopping simulator located on the levee crest. The coordinates indicate the general area where the test was performed.;;these tests are aimed at measuring the erosion rate of the clay layer underneath a grass sod on the landside slope of a levee, in order to enable the determination of the residual strength of the levee after failure of the grass. The results can be used to test and validate erosion models – both current models and future models.;Little is yet known on the erosion resistance of clay under wave overtopping, and how the results of small scale erosion tests could be used to determine the erosive behaviour of clay subjected to real life loads.;The grass was removed over a section of 3.5m x 4m wide, and a depth of 20 cm using a crane. Upstream of the test section the levee was covered with grass;;10 GoPro's for photogrammetry for monitoring the difference in erosion depth between waves and for determining the front velocities of waves;To be able to derive an erosion relation;;;;;;Erosion relation for wave overtopping on clay;;True;False;False; All DATA concerning Wave overtopping experiment bare clay section 2-2 data_type;data_descripion;date_date;data_find;data_media;data_media_find ;;;https://stowanl-my.sharepoint.com/:f:/g/personal/llhpp_stowa_nl/Ejr1ykRvpXpGn68Jqkp1CEwBEgnYxnRQ16FdIVvNvRxkrw;; All EQUIPMENTS concerning Wave overtopping experiment bare clay section 2-2 equip_type;equip_usage "- Wave overtopping simulator including pumps, pipelines, cranes for moving, etc ";"Wave overtopping simulator was used to offer a proper comparison against the erosion resistance of grass and as it is currently the most viable way of simulator up to real loading conditions in situ " All SENSORS concerning Wave overtopping experiment bare clay section 2-2 No sensors added
