During the Interreg Polder2Cs project overflow tests on a grass sloped levee have been executed. This dataset contains the processed data of the overflow tests executed in February and March 2021 on test stretches B_OF6, B_OF7, B_OF8, B_OF9, B_OF10 and B_OF11 in the Belgian part of the Hedwige and Prosperpolder. Measurements of water level and flow velocity were executed (time series). With the camera system, the damage of the grass cover layer and also the water flow (with low frequency camera monitoring) during the tests were measured. For the different test stretches, the processed data contain timeseries data of water level and velocity, damage recordings, recordings of the water flow and LSPIV and PTV measurements. moreRaw data captured with the measurement system during the overflow tests on test stretches B_OF6, B_OF7, B_OF8, B_OF9, B_OF10 and B_OF11 in the Belgian part of the Hedwige and Prosperpolder were processed using Python. This dataset contains timeseries of water level and velocity for each test stretch. Photos of the flow field from different cameras were stitched into one for test stretches B_OF6, B_OF8, B_OF9, B_OF10 and B_OF11, photos of the damage from different cameras were stitched into one for test stretches B_OF6, B_OF8, B_OF9 and B_OF11. For test stretches B_OF8 and B_OF11 the velocity field was calculated from the camera images of the LSPIV measurements and for test stretch B_ OF8 flow velocity was calculated from the PTV-measurements.
