Abstract: Infrastructure planning increasingly relies on projections of future conditions, usually modified by factors such as climate change as well as a range of development scenarios. Design criteria are often expressed in terms of event return periods, and long term hydraulic simulation can determine which events will prove to be critical. However wider adoption of this technology depends on overcoming uncertain solution reliability, and improved treatment of overfalls, floodplain corrections and sudden boundary changes is discussed. Run times and data analysis have previously added further logistical constraints, but acceptable model performance is now demonstrated to be practical.
