Interreg Polder2C's: Discharge and equilibrium velocity values of hydraulic measurements for derivation of Manning roughness of the grass cover layer

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.
