This model does not require a licence dongle to run.
 
==Cross Sections, Grid Setup and Cell Size==
The model is set up as a TUFLOW 1D/2D model. <br>
The 2D domain is modelled using 100ft (~30.5m) and 200ft (~60.96m) cell sizes.
Cell size selection is managed through the use of variables.
 
=Solution to Challenge 3=
A sample solution has been presented, courtesy of BMT WBM.
 
1D sections spacing were generally between 500ft and 1000ft, except at structures where they are more frequent.<br>
==Cross Section Spacing, Grid Size, Mesh Element Size, and Effects of Hydraulic Structures==
1D sections spacing were generally between 500ft and 1000ft (except at structures). Structures were modeled with additional energy loss, to simplify the model a value of 1.0 V2/2g was used for all structures in the main creek.
The model was set up as a TUFLOW 1D/2D model. Two different resolutions for the floodplain were simulated using 100ft and 200ft cell sizes.

Linking between 1D/2D was along the top of the levees.
 
All outflow from the model was assumed to be only via the main creek (ie. there was no water level boundary applied to the 2D overbank domain).
 
The number of cross sections, grids, or mesh elements used were as follows:<br>
