MUSIC by eWater – market leading stormwater management software

Designed to help urban stormwater professionals visualise possible strategies to tackle urban stormwater hydrology and pollution impacts.

As an aid to decision-making, MUSIC – Model for Urban Stormwater Improvement Conceptualisation –  predicts the performance of stormwater quality management systems. It is intended to help organisations plan and design (at a conceptual level) appropriate urban stormwater management systems for their catchments.

"MUSIC is an easy to use modelling tool for both simple and highly complex urban stormwater systems using water sensitive urban design.  It can simulate urban stormwater systems ranging from a suburban block up to a whole suburb or town (0.01 km2 to 100km2). The time scale can start at 6 minutes and stretch up to 24 hours.

What’s new in MUSIC v6.2

In this release, we have added several enhancements including:

  • Landuse Zoning / Surface Type categories within the Urban Source Node – these will allow for a better “split catchment modelling approach”. The new categories have guided default EMC/DWC values (see Editing Source Node Properties)
  • New Results Manager and charting tool that offers:
    • Different chart types, e.g. Line, Exceedance, and Cumulative.
    • Different statistics and data filtering options.
    • Direct graphing of flux files. This allows various analysis of hydrological matrixes, such as:
      • Time series results comparison of multiple scenarios (e.g. pre and post)
      • Time series soil moisture for the Bioretention Node 
      • Inundation frequency analysis for the Wetland Node (and other storage nodes)
      • Calculation of the number of wet/dry/runoff days
      • Calculation of Stream Erosion Index
      • Calculation of Volumatic Runoff Coefficient.

Also available since version 6 is MUSIC-link. This major new feature streamlines the process of assessing the compliance of water sensitive urban designs submitted against guidelines from a council or other Local Government Authority. Currently, fourteen councils throughout Australia have joined in MUSIC-link.
