HUN AWRA-LR Model v01

Abstract

The 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 metadata contains data for two models: AWRA-L and AWRA-R. In the Macquarie-Tuggerah-Lake (MTL) coastal subregion, only AWRA-L modelling was conducted; in the Hunter subregion both modelling were conducted and AWRA-L flow outputs provided as model inputs for AWRA-R.

AWRA-L

The metadata within the dataset contains the workflow, processes, inputs and outputs data. The workflow pptx file under the top folder provides the top level summary of the modelling framework, including three slides. The first slide explains how to generate global definition file; the second slide outlines the calibration and simulation for AWRA-L model run; the third slide shows AWRA-L model post-processing for getting streamflow under baseline and coal mine resources development.

The exectable model framework is under the Application subfolder

Other subfolders, including model calibration, model simulation, post processing, contain the associated files used for model calibration, simulation and post processing, respectively.

Documentation about the implementation of AWRA-L in the Hunter bioregion is provided in BA HUN 2.6.1.3 and 2.6.1.4 products.

AWRA-R

The metadata within the dataset contains the workflow, processes, input and output data and instructions to implement the Hunter AWRA-R model for model calibration or simulation.

Each sub-folder in the associated data has a readme file indicating folder contents and providing general instructions about the workflow performed.

Detailed documentation of the AWRA-R model, is provided in: https://publications.csiro.au/rpr/download?pid=csiro:EP154523&dsid=DS2

Documentation about the implementation of AWRA-R in the Hunter bioregion is provided in BA HUN 2.6.1.3 and 2.6.1.4 products.

Purpose

BA surface water modelling in the Hunter bioregion

Dataset History

There are two sections, the first section describing AWRA-L, the second section describing AWRA-R.

Section 1 - AWRA-L

The directories within contain the input and output data of the Hunter AWRA-L model for model calibration, simulation and post-processing.

The calibration folder contains the input and output subfolders used for two model calibration schemes: lowflow and normal. The lowflow model calibration puts more weight on median and low streamflow; the normal model calibration puts more weight on high streamflow.

The simulation folder contains only one replicate of model input and output as an example.

The post-processing folder contains three subfolders: inputs, outputs and scripts used for generating streamflow under the baseline and coal mine resources development conditions. It contains the post-processing for the two subregions (MTL and HUN). In the MTL coastal subregion, the AWRA-L postprocessing results were final outputs, while in the HUN subregion AWRA-L flow outputs were model inputs for AWRA-R (Details below).

Input and output files are the daily data covering the period of 1953 to 2102, with the first 30 years (1953-1982) for model spin-up.

Documentation about the implementation of AWRA-L in the Hunter bioregion is provided in BA HUN 2.6.1.3 and 2.6.1.4 products.
