Updated Tutorial - Modelling Bridges

[par 0]

Hi All,

 

Module 6 of the TUFLOW tutorial is now available. This module introduces a large bridge structure that spans the creek and part of the floodplain. The model includes both a a 1D bridge channel and 2D flow constriction layer to represent the bridge.

 

The TUFLOW tutorial can be found here: http://wiki.tuflow.com/index.php?title=Tutorial_Module06

 

The required module data and completed models are available on our TUFLOW downloads section: http://www.tuflow.co...ial Models.aspx

 

If you have any questions, clarifications or feedback, please email support@tuflow.com.

 

Regards

Phillip

Dear TUFLOW Users, 

 

The Module 6 TUFLOW tutorial (Modelling Bridges) is currently being reviewed and updated to include a series of traditional bridge modelling approaches:

- 1d bridge and weir;

- 1d bridge with 2d weir flow; and

- 2d flcsh only.

 

This should be completed over the coming month with the aim to assist you in conceptualisating your bridge setups.

 

Will keep you posted, cheers Mitch.

Dear TUFLOW Users, 

 

The Module 6 TUFLOW tutorial (Modelling Bridges) has been updated to assess a series of bridge modelling approaches including:

- 1D bridge with 2D weir flow;

- 1D bridge and weir; and

- 2D only using a layered flow constriction.

 

This tutorial is currently available for Mapinfo, ArcGIS and QGIS users here: http://wiki.tuflow.com/index.php?title=Tutorial_Module06 

or through our wiki mainpage: http://wiki.tuflow.com/index.php?title=Main_Page

 

The required module data and completed models are available on our TUFLOW downloads section: http://www.tuflow.com/Tuflow%20Tutorial%20Models.aspx

 

The setups are provided as example only. For your specific bridge structure you will need to estimate bridge energy loss coefficients, ideally with reference to measured data. If this is unavailable (which is typically the case), loss coefficients can be sourced from relevant literature such as the methods outlined Hydraulics of Bridge Waterways (Bradley, 1978). 

 

For application of 2D layered flow constriction form losses, a handy reference is the Technical Memo on modelling bridge piers in 2D using TUFLOW available at: http://www.tuflow.com/Library.aspx?TechnicalDocuments

 

If you have any questions, clarifications or feedback, please email support@tuflow.com.

 

Kind regards, Mitch.
