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 November and December 2021 on on test stretches NL_OF2, NL_OF3, NL_OF4, NL_OF5b, NL_OF5c, NL_OF6, NL_OF7, NL_OF8, NL_OF9, NL_OF10 and NL_OF11 in the Dutch 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. 

","EngDescr":"

Raw data captured with the measurement system during the overflow tests on on test stretches NL_OF2, NL_OF3, NL_OF4, NL_OF5b, NL_OF5c, NL_OF7, NL_OF8, NL_OF9, NL_OF10 and NL_OF11 in the Dutch 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 damage from different cameras were stitched into one for test stretches NL_OF2, NL_OF3, NL_OF4 and NL_OF9. For test stretch NL_OF3 the velocity field was calculated from the camera images of the LSPIV measurements and the flow velocity was calculated from the PTV-measurements.

","OrigAbstract":"

Tijdens het Interreg Polder2Cs-project zijn overlooptests uitgevoerd op een met gras begroeide dijk. Deze dataset bevat de verwerkte gegevens van de overloopproeven die in november en december 2021 zijn uitgevoerd op de testtrajecten NL_OF2, NL_OF3, NL_OF4, NL_OF5b, NL_OF5c, NL_OF6, NL_OF7, NL_OF8, NL_OF9, NL_OF10 en NL_OF11 in het Nederlandse deel van de Hedwige- en Prosperpolder. Er zijn metingen van het waterpeil en de stroomsnelheid uitgevoerd (tijdreeksen). Met het camerasysteem zijn de schade aan de graslaag en ook de waterstroming (met laagfrequente camerabewaking) tijdens de tests gemeten. Voor de verschillende testtrajecten bevatten de verwerkte gegevens tijdreeksgegevens van het waterpeil en de snelheid, schadeopnames, opnames van de waterstroming en LSPIV- en PTV-metingen.

","OrigDescr":"

De ruwe gegevens die met het meetsysteem zijn verzameld tijdens de overloopproeven op de testtrajecten NL_OF2, NL_OF3, NL_OF4, NL_OF5b, NL_OF5c, NL_OF7, NL_OF8, NL_OF9, NL_OF10 en NL_OF11 in het Nederlandse deel van de Hedwige- en Prosperpolder zijn verwerkt met Python. Deze dataset bevat tijdreeksen van waterstanden en snelheden voor elk testtraject. Foto's van de schade, gemaakt met verschillende camera's, zijn samengevoegd tot één foto voor de testtrajecten NL_OF2, NL_OF3, NL_OF4 en NL_OF9. Voor testtraject NL_OF3 is het snelheidsveld berekend op basis van de camerabeelden van de LSPIV-metingen en is de stroomsnelheid berekend op basis van de PTV-metingen.
