1D-2D linked models are able to utilise the individual benefits of 1D and 2D solution schemes. In this example, the 1D Flood Modeller scheme is used to represent the watercourses where the flow is essentially uni-directional. A 2D scheme is suited to the representation of floodplains where more complex flow patterns may occur. <br>

As [[Tutorial_Module01Tutorial_Module01_Archive#Reviewing_Model_Performance | discussed in Module 1 of the TUFLOW Tutorial Model]], the main watercourse channel is not very well represented using the 5m 2D cell size. In parts, the watercourse is only 5-10m wide and the 5m cell size could be considered too coarse to accurately represent the watercourse topography.<br>
[[file:Poor_2d_rep.png|400px]]<br>
Using a cell size that is coarse relative to the width of the watercourse channel may reduce the accuracy of the conveyance in the channel. There are two options for improving the representation of the creek channel:<br>
* decrease the width of the 2D cells; and/or
* model the channel as a 1D network, dynamically linked to the 2D domain (the floodplain).
In the [[Tutorial_Module01Tutorial_Module01_Archive#Advanced_.28Optional.29 | optional section of Module 1 of the TUFLOW Tutorial Model]], we looked at reducing the cell size to get a better representation of the channel. In this module we will adopt the second approach of modelling the creek as 1D elements using Flood Modeller.<br>
 
TUFLOW may be dynamically linked to 1D networks using the hydrodynamic solutions of ESTRY (TUFLOW 1D), Flood Modeller (previously ISIS), XP-SWMM and 12D Solutions’ Dynamic Drainage.<br>

Modelled results can be processed, reviewed and visualised in many different packages.<br>
