78;B-OF03 Overflow Test (High Discharge);Strength test;By generating overflow over a levee crest, using a custom built overflow generator, the strength of the levee cover against erosion and/or failure is evaluated. The B-OF03 test is conducted over a section of 1 m wide (instead of 2 m by default) in order to evaluate the impact of a higher discharge compared to the reference test.;False;False;True;False;False;False;2020-11-10 00:00:00;2020-11-11 00:00:00;;10.0;;IV;51.341395;4.23859;11.2;Landward side of the levee.;"Lambert'72 coordinates: X=140930.2m; Y=225741.8m.";Perform an overflow test on a narrower section in order to achieve a higher specific discharge.;- How does the levee cover behave under higher overflow discharge in comparison to reference case B-OF01.;Levee slope in visually good conditions.;Overflow during 10:00 hours with a typical discharge of 340 L/s.m over a width of 1 m.;- Overhead cameras (4) - Acoustic water height sensors - Electromagnetic current velocity sensors - Discharge sensor (EM or acoustic);"Description of the hydraulic conditions of the overflow. The setup is described in Vercruysse et al. (2022): ""Design and application of an overflow generator."" (Ref WL2022R20_047_1)";;During the test, it was observed that soil eroded slowly and exposed grass roots, without creation of any significant damage that would lead to imminent failure of the levee slope.;Slope surface shows signs of erosion and barren patches where vegetation is removed, but the clay cover layer is intact. No failure has occurred.;The higher discharge experiment did not lead to strong(er) erosion or damage evolution than observed in the reference case (B-OF01).;Factual data report + Annexes: https://stowanl-my.sharepoint.com/:f:/g/personal/llhpp_stowa_nl/EvdAZOO-zylAqEWS8-SEiC4BQ5xCAuFXklsysJXnkcVYaQ?e=XDeXq8;An integration report will be added later (February 2023) as knowledge document.;under development;True;False;False;
