MUSIC is the Model for Urban Stormwater Improvement Conceptualisation, first developed by the music MUSIC Development Team of the CRC for Catchment Hydrology, and now enhanced by the eWater Cooperative Research Centre.


The Cooperative Research Centre for Catchment Hydrology (CRC) addressed these deficiencies through its Urban Stormwater Quality Research Program. The program's research culminated in music MUSIC (the Model for Urban Stormwater Improvement Conceptualisation). As an aid to decision-making, music MUSIC predicts the performance of stormwater management systems. It is intended to help organisations plan and design (at a conceptual level) appropriate urban stormwater management systems for their catchments. This latest version of music MUSIC contains numerous improvements through further analysis of the science, and learnings gathered while applying music MUSIC into new environments.

A pilot version of music MUSIC was released in March 2001 for beta testing by Melbourne Water, Brisbane City Council and associated consultants. Following the eight-month testing period, music MUSIC Version 1 was released to the stormwater industry at large. music MUSIC Version 2 (December 2003) extended the capabilities of the original program through additional calculation and presentation features, greater ability to export data for external analysis, and substantially smaller saved files. music MUSIC Version 3 introduced the Life Cycle Costing module, provided two additional treatment nodes (rainwater tanks and infiltration basins), and offered further options to import and export model data. music MUSIC Version 4 significantly improved the bioretention node based on the outcomes of research from the Facility for Advancing Water Biofiltration and added further functionality improvements to the model.

The model's algorithms are based on the known performance characteristics of common stormwater improvement measures. These data, derived from research undertaken by the former CRCCH, the eWater CRC, affiliated research agencies and other organisations, represent the most reliable information currently available in our industry. Nonetheless, knowledge gaps remain. music MUSIC will evolve as researchers, and the stormwater industry generally, conducts further research into:
