MUSIC Webinar Series - Bioretention Modelling for Healthy Plants using MUSIC


"Many Councils have recognised the potential benefits of trees and urban greening to improve amenity, mitigate urban heat island and also provide stormwater quality treatment. To this end, many Councils have established ambitious tree canopy cover targets. Water is essential for healthy plant growth and passive irrigation of trees through a water sensitive urban design approach can greatly increase the effectiveness of tree planting efforts. However, the behaviour and performance of passively irrigated tree pits relative to conventional trees is not yet well understood.

Update to residence time calculations


We've made some improvements to the algorithm that calculates wetland residence time as of 4/10/2015. This slightly improves accuracy for marginal cases. For most models there will be no observable change although some will see an increase or decrease in residence time of one day. A residence time with a fractional day is now reported if the residence time falls between percentiles with different residence times.

Revised guideline parameters for Melbourne Water


On 15/3/2014 the guideline parameters for Melbourne Water were updated.

The changes reduce the sensitivity of the MUSIC Auditor to avoid flagging submerged zone system parameters. The presence of a submerged zone is now identified as an advisory for the authority to check that the sizing and design of the system is reasonable.
The update also provides support for Version 4 models that have been run in version 5 or 6 and corrects a bug with auditing models with large numbers of bioretention nodes.
