New Climate Change Functionality in Qube

We are pleased to announce that we have just released the new climate change functionality in Qube!

Qube is an online tool that models natural flow statistics and daily time series throughout the UK and Ireland for gauged and ungauged catchments. The new functionality provides a rapid method for users to estimate climate change adjusted annual flow duration curves and annual and monthly mean flows in any catchment in GB.

Recently there has been an increased need for many users to estimate the impact of climate change on water resources. To facilitate this in Qube, the CERF2-HadUK1 rainfall-runoff model has been run using the UKCP18 eFLaG gridded meteorological datasets2 3 to generate estimates of daily flows for ~11,000 donor catchments across Great Britain for the near (2020-2049) and far (2050-2079) future. Percentage changes between current and future flows for key flow percentiles, and annual and monthly mean flows, have been computed at these donor catchments. Within Qube, the percentage changes are transferred to any catchment through the selection of ‘similar’ donor catchments and applied to the Qube natural FDC and mean flows.

For further details please see our climate change report at https://www.hydrosolutions.co.uk/app/uploads/2024/04/Development-of-climate-change-adjusted-flow-statistics-in-Qube-v2.pdf.

We presented the new functionalities at a webinar on 2nd July. If you missed it or would like to watch it again, please visit our website at https://www.hydrosolutions.co.uk/software/qube/tutorials/.
