A comprehensive understanding of the performance of box gutters and downpipes is critical to ensure a successful building roof drainage system design. Poorly designed roof drainage systems can result in significant damage to a building's structure and contents. Current codes and standards used to regulate box gutter and downpipe designs in Australia have often been limited by a lack of empirical research studies and they often do not reflect the complex flow environments experienced in real roof drainage systems.
A new, full-scale roof drainage research facility has recently been constructed at the University of the Sunshine Coast in Australia to undertake research into how performance-based testing of box gutters, downpipes and overflow systems can be used to improve understanding of the hydraulic conditions that occur during common and extreme rainfall events.
