GAL AWRA-L 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 is about AWRA-L model used in the Galilee surface water numerical modelling.

The metadata contain the workflow, processes, inputs/outputs data and the script used to process the model outputs. 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.

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

Documentation about the implementation of AWRA-L in the Galilee subregion is provided in BA GAL 2.6.1.3 and 2.6.1.4 products.

Purpose

BA surface water modelling in the Galilee subregion

Dataset History

The directories under this dataset contain the input and output data of the Galilee 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 weights on median and low streamflow; the normal model calibration put more weights 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.

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 Galilee subregion is provided in BA GAL 2.6.1.3 and 2.6.1.4 products.
