16. Do you believe that the accuracy of your model outputs will be increased, if you had
a more accurate spatially distributed generated time series hydrological data set at the
scale of interest where you can simply plug and play with your model?
17. Do you know of an open source hydrological modelling platform that you highly
recommend, such as PCRaster http://pcraster.geo.uu.nl/pcraster

19. Would you be interested in having a powerful calibration tool to:
(1) optimize your parameters,
(2) have the uncertainties in the predictions,
(3) determine the key parameters
which may vary during time (e.g. dry or wet period)?
20. If you perform optimisation or sensitivity analyses, which open
source optimisation
tools do you use?
21. For the long term, would you be interested in participating in developing a
hydrological platform which better takes advantage of distributed soil information and
computes lateral flow?
22. Have you got any general comments?
