Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
On the basis of two conceptual models, Nash and O'kelly, the rainfall-runoff model Hydrolin has been made. Using the method of moments, first estimates are made for the various parameters of the models. An extra option is the further improvement of all values of the parameters by an automatic stepwise procedure where the performance is evaluated by the so-called "coefficient of determination". Both models have been applied to real data from a catchment in southern-France. It appears that these models can cope with data from complex-storms and their resulting hydrographs and that the ''coefficient of determination" is excellent criterion for the goodness of fit of the model parameters.
