OpenCLIM - Catchment Flow Metrics

This dataset contains flood, drought, and flow metrics calculated as part of the OpenCLIM (Open CLimate Impacts Modelling framework) project. All metrics have been calculated for 698 UK catchments from timeseries of daily river flow simulated by the hydrological models SHETRAN and HBV by teams from Newcastle University and the University of East Anglia respectively for historical and future periods. All analysis code is available on GitHub (https://github.com/OpenCLIM/OpenCLIM-SHETRAN_Flow_Analysis). Climate change simulations were driven by bias corrected UKCP18 data from 01/12/1980 to 30/11/2080. Datasets from all 12 regional climate models (RCMs) were used and are presented separately. Flow metrics are given for 698 catchments in the UK at catchment outlets/gauge locations: https://nrfa.ceh.ac.uk/data/search. These data can be used for the continued analysis of climate impacts and for comparison with future studies. File naming convention: Project_Data_Model_ClimateDriver_ScenarioNumber_ScenarioNote_Metric.csv Scenario notes: Sc01: Land use was taken from baseline Urban Development Model (UDM) setups with no Natural Flood Management (NFM) adaptations applied. Sc02 & Sc06: Land use was taken from baseline UDM setups with NFM max/moderate adaptations applied. Sc03: Land use was taken from storylined UDM setups (2050 and 2080) for SSPs 2 and 4. No NFM adaptations were applied. For SHETRAN, only catchments with UDM changes relative to the baseline simulations or the previous UDM year were simulated. Further information, including descriptions of the urban development model (UDM) and natural flood management (NFM) setups, is provided in the supplementary README.txt alongside the data. UKCP18 - UK Climate Projections 2018 (UKCP18) is a climate analysis tool that forms part of the Met Office Hadley Centre Climate Programme.
