I know there are a lot of uncertainties over current climate change predictions and applications within hydraulic modelling, but I was after some input on how people currently apply current climate change predictions to model runs, in particular time series rainfall.

Design storms are relatively 'simple' with a standard uplift factor applicable ranging from anywhere between 5 - 30% obviously depending on location, design horizon etc.

However, from looking at time series rainfall there seems to be a lot more complications. Without going into too much detail the general consensus from UK CC predictions is that winters will get wetter and summers will get drier, but the storms in the summer will increase in intensity and frequency.

Therefore it seems applying a blanket uplift to TSR will over-predict for example spill performance of overflows when looking at including climate change.

Or am I looking into it too much and a blanket uplift approach is acceptable?
