MUSIC models the infiltration system by taking into account infiltration through both the base and sides of the system (unlike MUSIC v3 which assumed that infiltration occurred only through the base). It is important to note that there is no option to include lining of the base of the infiltration system. However, you can take into account lined walls, by subtracting them from the specified Infiltration Media Perimeter specified in MUSIC.Treatment in the infiltration system is assumed to occur only in the ponding (extended detention) zone; no treatment is modelled in the infiltration media. Whilst this is not strictly true, it must be remembered that MUSIC ‘loses’ water that is infiltrated and so there is no benefit in modelling the treatment performance further.
A conceptual diagram of the infiltration system properties in MUSIC is presented below:

Infiltration System Properties
The infiltration system properties dialogue box contains the parameters that describe the basic physical characteristics of the infiltration system. A description of each of the parameters is given below.
