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, River, Interpolate, Replicate or Conduit) and must not be the end node of a reach (ie, 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.

 

 

An X1DQ might be more appropriate where a Flood Modeller model stops and flows into an ESTRY model. The water level calculated by TUFLOW is applied as a time-varying head boundary in Flood Modeller. The Flood Modeller 1D node on the end of an X1DQ connection must be an HTBDY unit. This does not need to contain any data as this data will be overridden by the water levels provided by TUFLOW.
