Abstract
Roof collapses after significant rain events are becoming widely reported with a catastrophic loss of property, and in some cases, lives. Debris-blocked drains can be the culprit. To date, the effect of debris accumulation on flow rates of drainage systems has not been studied. This presentation describes a laboratory simulation of debris-blocked drains and the effects of inadequate drainage on roof assemblies.
