Over het archief
Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.
Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

| Abstract |
The optimization during calibration is performed based on an automatic procedure, followed by a visual control. During the optimization routine the parameter sets are selected based on 2 criteria: (1) absolute error on cumulated total flow at each time step, and (2) logarithmic Nash-Sutcliff efficiency. The first criterion aims to model the global flow pattern, the latter focuses mainly on the low flows. Overall, the performance of the calibrated VHM models is similar compared to the other lumped rainfall-runoff models already calibrated: PDM, NAM and WETSPA. The summarized results for each of the gauged sub catchments within the study area, allow the user to get insight in the performance of the VHM model for each of the involved sub catchments. Based on this information and the evaluation of the NAM, PDM and WETSPA models, the user can make a well-grounded decision on which model to use for the considered objective. |
