Numerical modelling is often used for climate impact studies in water resources management. It is, however, not yet highly accessible to many students of hydrology in Central Asia. One big hurdle for new learners is the scripting requirement for the preparation of relevant data prior to the actual modelling. We present a robust, open-source workflow and comprehensive teaching material that aims at bridging the gap between theoretical hydrological modelling know how and applied modelling for climate impact studies in Central Asia. The teaching material has been refined during two consecutive years and is being taken up by several professors teaching hydrological modelling in Central Asia.
