=Building a TUFLOW-Flood Modeller 1D-1D Connection=
Flood Modeller and TUFLOW will be considered linked if an ESTRY node in a 1D_nwk layer, and a Flood Modeller node in a Read GIS ISIS Nodes or Read GIS ISIS Network layer are snapped together (see Figure 3). Ensure that the 2 nodes are snapped, or that a snap tolerance is being used. The ESTRY node should have a 1d_nwk Conn_1D_2D attribute of either "X1DH" or "X1DQ". If Conn_1D_2D field is blank then “X1DH” is assumed (see Figure 4). Note that the upstream and downstream inverts for the ESTRY node linked to Flood Modeller should be set to -99999 unless the node is also being used to set the inverts of channels snapped to it.

It is not possible to have a HX connection to ESTRY and a X1DQ connection at the same node. This is because the X1DQ connection node is snapped to the Flood Modeller node and the model thinkthinks it's trying to connect a HX and X1DQ to the same Flood Modeller node. In this situation it would be necessary to insert a small dummy channel between the X1DQ node and the node connected to the HX boundary.
 
An example model containing both X1DH and X1DQ connection is available from support@tuflow.com. This is available as 2 models, one with direct snapping between nodes and the ESTRY channel and other which uses X-connectors.

The type or existence of a connection can be also be checked by viewing the Conn_1D_2D attribute in the 1d_nwk_N_ check layer as shown in Figure 7.
