Flooding is one of the major natural disasters.Projected rapid land use change, over the coming decades, when coupled with climate change could potentially lead to increased risk of flooding in urban catchments.No work has been undertaken to examine the impact of climate change in conjunction with land use change for the Bulimba Creek catchments in Australia.The RAMS model was firstly calibrated with observations and used to generate the flood hydrograph of raining frequency of occurrence for the period 2016-2045 using output from global climate models.Three land use scenarios were considered to evaluate the impact of the land use change on flooding.Flood frequency was found to increase for small flood events.Given the uncertainties with climate models and land use scenarios, impacts of climate and land use changes will need to be further assessed by combining a range of climate change and land use scenarios, and a range of modeling approaches and parameterization schemes.
