| Summary: | This study intends to look into modular-typed green wall, specifically with coconut peat as the growing
medium. Commonly, such design is attached to vertical outdoor wall. Therefore, it is suggested to direct roof
runoff to the green wall as an urban flood mitigation strategy. Characteristics of coconut peat are investigated
through experimental works. The application as urban runoff control is demonstrated through a modelling case
study of a typical commercial lot. SWMM model is developed by taking the advantage of its low impact
development interface to apply bio-retention system as a green wall. Scenarios of using dry and saturated
coconut peats are subjected to intense 15-minute 10-year ARI storm event. Outputs of the model suggest that
a straight column of green wall modules in 700 mm wide, 200 mm thick and 12000 mm high is capable to fully
capture the 6.3 m3 of total roof runoff generated by the design storm. Hence, the idea of adopting green wall
for urban flood mitigation is encouraging. |
