Bioretention filter media may be assumed to have a storage capacity of 0.4.
This has been calculated as the difference between the media porosity and field capacity from a number of studies.
- Marine sand: 0.51 - 0.06 = 0.45 [1]
- Marine sand with 10 % compost: 0.51 - 0.11 = 0.40 [1]
- Marine sand with 20 % compost: 0.53 - 0.12 = 0.41 [1]
- Marine sand with 20 % compost & 20 % topsoil: 0.52 - 0.16 = 0.36 [1]
- Sand: 0.46 - 0.1 = 0.36 [2]
- NC sandy bioretention mix: 47.7 - 7.0 = 40.7 [3]
- Bioretention soil I: 0.71 - 0.1 = 0.61 [4]
- Bioretention soil II: 0.52 - 0.1 = 0.42 [4]
- M minus mean θini: 0.76 - 0.32 = 0.44 [5]
