Namoi AWRA-L model

## **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 the AWRA-L model.  In the Namoi subregion both the AWRA-L and AWRA-R modelling were done. AWRA-L flow outputs were used as model inputs for AWRA-R.



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 two 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 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 Namoi subregion is provided in BA NAM 2.6.1.3 and 2.6.1.4 products.

## **Dataset History** 

AWRAL_Metadata



Overview of modelling sequence for AWRA-L and AWRA-R is given in  '..\AWRAL_Metadata\Namoi_Model_Sequence.pptx'.  Here AWRA-L is described.



The directorie contains the input and output data of the Namoi AWRA-L model for model calibration, simulation and post-processing. 



The model 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 model simulation input folder contains three folders as described below.



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



The pre-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 Namoi bioregion is provided in BA NAM 2.6.1.3 and 2.6.1.4 products.
