UWMH develops user friendly knowledge-intensive digital products and tools to ensure that new knowledge creates real-world impact. We also look at the business case and market opportunities to turn research prototypes into practical, large scale implementations.


HyetosMinute is an R package for temporal stochastic simulation of rainfall process at fine time scales, i.e. from daily down to 1-minute, based on the Bartlett-Lewis rectangular pulse model.


It operates on several modes and combinations of them (depending on data availability), such as the operational or the testing mode, and simple sequential simulation or disaggregation.

In the latter case, it uses the Bartlett-Lewis model to generate rainfall events along with proven disaggregation techniques that adjust the finer scale (e.g., hourly) variables to obtain the given coarser scale (e.g., daily) value.

The package comprises various variants of the Bartlett-Lewis model, graphical capabilities, import/export tools as well as an optimization tool for the estimation of model parameters.
