Much of the design information available for road surface drainage systems throughout the world uses results from scale-model testing for the determination of capture rates for gutter inlets. It has been shown that scale modelling can be unreliable in predicting inlet capture performance. In the case that capture capacity is underestimated, inefficiencies are introduced into the drainage network design, incurring additional costs to the authority responsible for construction of the stormwater system. Alternatively, installation of undersized components may lead to future flooding problems and leave the authority potentially open to litigation. The paper concludes that significant benefits in terms of reduced component sizing together with minimising litigation liability can be achieved through the use of more accurate information.
