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 2020 on test stretches B_OFl, B_OF2, B_OF4 and B_OFS in the Belgian part of the Hedwige and Prosperpolder and on test stretches NL_OFl and NL_OFS 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 test stretches B_OF1, B_OF2, B_OF4 and B_OF5 in the Belgian part of the Hedwige and Prosperpolder and on test stretches NL_OF1 and NL_OF5 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 flow field from different cameras were stitched into one for test stretches B_OF1 and B_OF5, photos of the damage from different cameras were stitched into one for test stretches B_OF2 and B_OF5. For test stretch NL_OF1 the velocity field was calculated from the camera images of the LSPIV measurements and for test stretch NL_ OF5 flow velocity was calculated from the PTV-measurements.
","OrigAbstract":"Tijdens het lnterreg Polder2Cs-project zijn overlooptests uitgevoerd op een met gras begroeide dijk. Deze dataset bevat de verwerkte gegevens van de overstromingstests die in november 2020 zijn uitgevoerd op testtrajecten B_OFl, B_OF2, B_OF4 en B_OFS in het Belgische deel van de Hedwige- en Prosperpolder en op testtrajecten NL_OFl en NL_OFS in het Nederlandse deel van de Hedwige- en Prosperpolder. Er zijn metingen uitgevoerd van het waterpeil en de stroomsnelheid (tijdreeksen). Met het camerasysteem werd 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 waterpeil en snelheid, schadeopnames, opnames van de waterstroming en LSPlV- en PTV-metingen.
","OrigDescr":"De ruwe gegevens die met het meetsysteem zijn vastgelegd tijdens de overlooptests op de testtrajecten B_OF1, B_OF2, B_OF4 en B_OF5 in het Belgische deel van de Hedwige- en Prosperpolder en op de testtrajecten NL_OF1 en NL_OF5 in het Nederlandse deel van de Hedwige- en Prosperpolder, zijn verwerkt met Python. Deze dataset bevat tijdreeksen van het waterpeil en de stroomsnelheid voor elk testtraject. Foto's van het stromingsveld van verschillende camera's werden samengevoegd tot één foto voor testtrajecten B_OF1 en B_OF5, foto's van de schade van verschillende camera's werden samengevoegd tot één foto voor testtrajecten B_OF2 en B_OF5. Voor testtraject NL_OF1 werd het snelheidsveld berekend op basis van de camerabeelden van de LSPIV-metingen en voor testtraject NL_OF5 werd de stroomsnelheid berekend op basis van de PTV-metingen.
