Advisory Group and Task Force Subcommittee Reports Water Forward Task Force Meeting | April 14, 2021 Aquifer Storage and Recovery Technical Advisory Group Presented Phase 1a project approach Session 1: • Discussion Session 2: • Project technical tasks • Community engagement/equity and affordability tasks • Discussion Climate Technical Advisory Group Presented Water Forward project background and previous climate analysis • Topic 1: General circulation models (GCMs) and climate scenarios to be used in analysis. In the Water Forward 2018 analysis, 20 GCMs from CMIP 5 were used for analysis. Discussed pros/cons of using CMIP5 or CMIP6 • Several CTAG members recommended using CMIP5 over CMIP6 because the 6 models are very new and the community has not had a chance to vet them yet • Could potentially still use CMIP6 if we were selective about which models to use • Need to evaluate whether CMIP6 provides data that CMIP5 does not different variables, different variable reporting frequencies, large ensembles, etc. • Start with CMIP5 and have the climate consultant automate the process so that CMIP6 data could be fed in as it is available • Get recommendation from consultant • Discuss GCMs appropriate for use in this region change) • Discussed selection of climate scenarios (for example, choosing RCPs or SSPs to represent various degrees of warming or other potential impacts of climate Topic 2: Downscaling methodology and downscaled GCM outputs • Discussed possible downscaling approaches appropriate for the Colorado River basin and Central Texas region • Discussed possible validation approaches for downscaled data outputs Questions and Discussion
