During the INTERREG-project Polder2C's 24 overflow tests were executed on a grass covered levee. The manning roughness value of the grass cover was calculated based on data of equilibrium velocity as function of discharge for overflow tests on test sections B-OF8, N-OF3 and N-OF4. This dataset contains the data for the calculation of the manning roughness value of the grass cover.
","EngDescr":"For test sections B-OF8, N-OF3 and N-OF4 the manning roughness value of the grass cover layer was derived based on the relation between the calculated equilibrium velocity and the measured discharge during the overflow test. For these test sections the equilibrium velocity was calculated based on the flow velocity derived from Particle Tracking Velocimetry.
","OrigAbstract":"Tijdens het INTERREG-project Polder2C zijn 24 overloopproeven uitgevoerd op een met gras begroeide dijk. De Manning-ruwheid van de grasbegroeiing is berekend op basis van gegevens over de evenwichtsstroomsnelheid als functie van de afvoer voor overloopproeven op testtrajecten B-OF8, N-OF3 en N-OF4. Deze dataset bevat de gegevens voor de berekening van de Manning-ruwheid van de grasbegroeiing.
","OrigDescr":"Voor de testgedeelten B-OF8, N-OF3 en N-OF4 werd de Manning-ruwheidswaarde van de graslaag afgeleid op basis van de relatie tussen de berekende evenwichtsnelheid en de gemeten afvoer tijdens de overloopproef. Voor deze testgedeelten werd de evenwichtsnelheid berekend op basis van de stroomsnelheid die werd afgeleid uit deeltjesvolgsnelheidsmetingen.
