Dataset: CLM AWRA HRVs Uncertainty Analysis

Description

Abstract

This dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.

This dataset contains the data and scripts to generate the hydrological response variables for surface water in the Clarence Moreton subregion as reported in CLM261 (Gilfedder et al. 2016).

Dataset History

File CLM_AWRA_HRVs_flowchart.png shows the different files in this dataset and how they interact. The python and R-scripts are written by the BA modelling team to, as detailed below, read, combine and analyse the source datasets CLM AWRA model, CLM groundwater model V1 and CLM16swg Surface water gauging station data within the Clarence Moreton Basin to create the hydrological response variables for surface water as reported in CLM2.6.1 (Gilfedder et al. 2016).

R-script HRV_SWGW_CLM.R reads, for each model simulation, the outputs from the surface water model in netcdf format from file Qtot.nc (dataset CLM AWRA model) and the outputs from the groundwater model, flux_change.csv (dataset CLM groundwater model V1) and creates a set of files in subfolder /Output for each GaugeNr and simulation Year:

CLM_GaugeNr_Year_all.csv and CLM_GaugeNR_Year_baseline.csv: the set of 9 HRVs for GaugeNr and Year for all 5000 simulations for baseline conditions

CLM_GaugeNr_Year_CRDP.csv: the set of 9 HRVs for GaugeNr and Year for all 5000 simulations for CRDP conditions (=AWRA streamflow - MODFLOW change in SW-GW flux)

CLM_GaugeNr_Year_minMax.csv: minimum and maximum of HRVs over all 5000 simulations

Python script CLM_collate_DoE_Predictions.py collates that information into following files, for each HRV and each maxtype (absolute maximum (amax), relative maximum (pmax) and time of absolute maximum change (tmax)):

CLM_AWRA_HRV_maxtyp_DoE_Predictions: for each simulation and each gauge_nr, the maxtyp of the HRV over the prediction period (2012 to 2102)

CLM_AWRA_HRV_DoE_Observations: for each simulation and each gauge_nr, the HRV for the years that observations are available

CLM_AWRA_HRV_Observations: summary statistics of each HRV and the observed value (based on data set CLM16swg Surface water gauging station data within the Clarence Moreton Basin)

CLM_AWRA_HRV_maxtyp_Predictions: summary statistics of each HRV

R-script CLM_CreateObjectiveFunction.R calculates for each HRV the objective function value for all simulations and stores it in CLM_AWRA_HRV_ss.csv. This file is used by python script CLM_AWRA_SI.py to generate figure CLM-2615-002-SI.png (sensitivity indices).

The AWRA objective function is combined with the overall objective function from the groundwater model in dataset CLM Modflow Uncertainty Analysis (CLM_MF_DoE_ObjFun.csv) into csv file CLM_AWRA_HRV_oo.csv. This file is used to select behavioural simulations in python script CLM-2615-001-top10.py. This script uses files CLM_NodeOrder.csv and BA_Visualisation.py to create the figures CLM-2616-001-HRV_10pct.png.
