1D Bridges: Difference between revisions

The following section looks at bridges using the 1D component of TUFLOW. For information on bridges in the 2D domain see <u>[[TUFLOW_2D_Hydraulic_Structures | 2D Hydraulic Structures]]</u> and <u>[[Tutorial_M11#Part_2_-_1D_Open_Channel_with_1D_Bridges_and_Weir_inflow_.282D.29_and_Outflow_.281D.29Tutorial M04|Tutorial ModuleM04 11- Tuflow]]</u>. Example models using bridges in 1D and 2D are available in the [[TUFLOW Example Models#Structures|TUFLOW Example Model Dataset]].<br>

<li>Create a 1d_tab HW (height vs width) .csv file for each standard shape (iei.e. set up a database of the irregular shapes). For the height value you can start at a value of zero so that height becomes depth (this might making the .csv files easier). As the height increases the width changes to reflect the particular irregular shape you are modeling. In the example below, the width at the top of the arch (2.1m) is set to a small value of 0.001m as opposed to zero as the HW becomes NA past the top of the irregular shape. <br>

<li>Any number of 1d_tab lines can reference the same .csv file, iei.e. you don't need to have a unique .csv file for every 1d_tab line. <br>
