South East Queensland Catchment Hydrological Model

This collection contains a US EPA Stormwater Management Model (SWMM), calibrated and validated for ten catchments with varying degrees of urbanisation in south east Queensland (SEQ). The catchments were calibrated against hourly streamflow data from 2009 to 2012. The catchments modelled are:\nTingalpa Creek at Sheldon;\nUpper Yaun Creek at Coomera;\nScrubby Creek at Karawatha Forest;\nBlunder Creek (Daintree Crescent) at Forest Lake;\nStable Swamp Creek at Sunnybank;\nOxley Creek at Heathwood;\nPimpama River at Kingsholme;\nBlunder Creek at Carolina Parade;\nSheepstation Creek at Parkinson;\nBlunder Creek at Durack.\nLineage: The shuffled complex evolution (SCE) algorithm used to optimise the model parameters is a general purpose global optimisation program and is available as a MATLAB routine (see “related materials”). Model performance was assessed using the NSE of both hourly and daily streamflows. A set of objective criteria were used to determine model performance. These included the model’s ability to reproduce the observed runoff series with:\n(a) hourly NSE values greater than 0.5 in at least 90% of subcatchments; and\n(b) daily NSE values greater than 0.6 in at least 90% of subcatchments.
