TUFLOW 1D Flood Modeller Connectivity: Difference between revisions

An ESTRY X1DH (the default) would be used for most Flood Modeller ESTRY links where TUFLOW is discharging into Flood Modeller. The discharge will be applied to the Flood Modeller 1D model as a lateral inflow. The Flood Modeller 1D node on the receiving end of an X1DH connection must be a channel unit (eg,e.g. River, Interpolate, Replicate or Conduit) and must not be the end node of a reach (i.e., distance to next cross section of zero). This is commonly used when representing a pipe network within ESTRY which discharges to an open channel represented in Flood Modeller as per Figure 1.

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 ISISX1D Nodes or Read GIS ISISX1D 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.
