Randall Cox prepared this discussion paper for the QWMN with a view to increasing the use of groundwater models in informing policy, program, and regulatory domains. It does this by prompting discussion about the interaction between groundwater modellers and the end users of the models. This paper could also be used to stimulate discussion in other modelling contexts as the issues raised extend beyond groundwater modelling.
Alluvium Consulting Australia Pty Ltd investigated and assessed options and opportunities for stream bank erosion modelling within the Great Barrier Reef (GBR) catchments. This study investigated a range of stream bank erosion modelling approaches and assessed their applicability to GBR catchment streams.
This report assessed four different stream bank erosion prediction approaches:
- The Dynamic SedNet stream bank erosion model
- Bank Assessment of Non-point Source Consequence of Sediment approach (BANCS)
- The Bank Stability and Toe Erosion Model (BSTEM)
- Stream type based approach and multi-temporal analysis
For each model an overview is provided, along with examples of application, limitations and research opportunities within the context of stream bank erosion prediction in the GBR catchments.
A key finding of the Alluvium Review of existing stream bank erosion models and options report highlighted the difficulty in accurately predicting stream bank erosion in all river typologies that exist within Great Barrier Reef catchments. In response, a follow-on project by Alluvium explored the accuracy and parameterisation of the Dynamic SedNet model currently used within the Paddock to Reef program in a range of different river types.
BMT Commercial Australia, in collaboration with The University of Western Australia and Healthy Land and Water investigated data driven models and ensemble machine learning techniques to improve predictions of water quality model outputs. This report summarises the project findings in context of a south-eastern Queensland catchment.
Following the completion of the critical review of climate change and water modelling in Queensland project, delivered in partnership with the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and University of Newcastle, Alluvium Consulting Australia has developed a stand-alone evaluation criteria and a scoring system to help assess the readiness of water models to account for or incorporate climate change in their use.
This independent resource, suitable for use by practitioners in reviewing a model’s treatment of climate and to support decision makers, is now available for application.
This project provides data improvements and estimation techniques that might allow hillslope erosion predictions of the Paddock to Reef catchment modelling for Reef Plan (for grazing lands) to be more sensitive to cover and management improvements. Delivered by Griffith University, this project includes data products for predictions of runoff depth and the peak runoff rate, at time and spatial scales for improved P2R Catchment modelling for Reef Plan.
HowLeaky is a software model that has been designed to assess the impacts of different land uses, soil conditions, management practices and climate-types on water balance and water quality. This document aims to provide HowLeaky users and developers with a detailed scientific description of the simulation model contained within the HowLeaky software (Version 5.49). This includes documentation of the scientific model equations, algorithms and descriptions of the input and output parameters. Sample input parameter values for different submodels are provided in the appendices.
This document does not aim to provide any information about the running of the software nor the features of its user-interface.
This project assessed Queensland’s current ability to incorporate climate variability and climate change projections in water models. Bringing together an experienced team of hydrologists, hydroclimate scientists, water quality scientists and practitioners, Alluvium Consulting Australia delivered the project in partnership with the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and University of Newcastle. Using the best available science, the project provided a clear pathway to consistent, robust modelling approaches for assessing climate change in Queensland water models.

This report reviews the current understanding of gully erosion and river sediment transport processes in Queensland catchments, and details how these processes have been represented in water quality models over the last 20 years. Developed through a consensus approach, the report identifies the research, data collection and conceptual design needs to improve these modelling practices, to make them more relevant to the growing needs of land management agencies and communities.
This catalogue provides a concise overview and collation of the major water models currently used by the Queensland Government. It is a resource for researchers and students to better understand the scope and range of models being applied by Queensland Government agencies and utilise these tools and applications for teaching and collaborative research projects.
This paper synthesises existing knowledge and experience on good water modelling practices and principles. It provides guidance for new and existing water model development efforts and informs end users and decision makers about what distinguishes good modelling practices from poor ones.
This document summarises the presentations given and issues discussed at the Forum attended by representatives from government agencies, public research bodies, universities, statutory authorities, not-for-profit organisations and the private sector.
Modelling of pollutant loads entering the Great Barrier Reef (GBR) is undertaken as part of the Paddock to Reef Integrated Monitoring, Modelling and Reporting Program (P2R). This project has investigated methods for integrating paddock and catchment scale modelling to improve representation of daily constituent concentrations going into the reef.
