NON-LINEAR RAINFALL RUNOFF MODEL - URBS
1. Purpose and Objectives
An event based runoff routing model suitable for integrated catchment management and flood forecasting.
URBS-CM is a non-linear runoff-routing networked model of sub-
catchments based on centroidal inflows. Three routing models are available to describe catchment and channel storage routing behaviour. The Basic model is a RORB-like model (Mein, R.G., E.M. Laurenson, and T.A. McMahon
(a) streamlined access to hydrological data;
Catchment specification, recorded river flows or heights, rainfall data and rating curves if river height data are either input or required as output. The catchment specification contains the subcatchment descriptions
and river reach details used to characterize the hydrology of the river catchment being studied.
Screen plots of observed and modelled hydrographs and rainfall hyetographs. A series of output files are generated containing depths of excess rainfall, observed and modelled river discharges and heights (if
rating tables are present), sediment washoff and traffic disruption information.
5. Operational requirements and restrictions
The software operates on IBM compatible microcomputers. A 486MHz computer with VGA screen is adequate to run the package. No additional software is required to run the package. The package does not require specialized installation. A user manual is provided but specialized hydrological knowledge is required to use the model effectively.
6. Form of presentation
The package is provided as a suite of PC-DOS/Windows 32 bit console executable programs written in the C language. A comprehensive user manual and example files are included. The language used throughout is English.
7. Operational experience
The model has been used successfully for both design and operational flood hydrology in Australia. The URBS model is included as one of the models used by the Australian Bureau of Meteorology for flood forecasting.
The model should be applicable to other parts of the world.
8. Originator and technical support
The model and software has been developed by Don Carroll over a number of years. Development is ongoing and new versions of the software are released as developments occur. The software package is released as
Shareware and formal support for its use is not available. The manual and examples should be sufficient to guide the user. Some guidance on the use of the model by the Bureau of Meteorology is available from the HNRC for Australia.
10. Conditions on use
The use of URBS in any studies should be acknowledged in any reports or papers resulting from those studies.
Use of URBS is conditional on obtaining a license for use from Don Carroll. The license is on a single site multi-user basis.
