6.10 Hydraulic Structures

6.10.1 Command Status

Optional - 3D features can be optionally applied to the structure implementations specifed during 2D HD model construction.

6.10.2 Description

TUFLOW FV supports a range of hydraulic structure connection types. These are described in Section 5.17.2.2. The behaviour of these connection types can be modified as part of a 3D HD simulation.

6.10.3 Structure Connection Types

Structure connections are defined using one of the methods described in Table 5.45. The behaviours of these connection types in 3D can be modified by setting a vertical distribution across a column of cells (Section 6.9.3.1)

6.10.3.1 Vertical Distribution

The flow of water through 3D connection types can be controlled by specifying Vertical Coordinate Type and Vertical Distribution File. The commands and syntax for doing so are the same as that described in Section 6.9.3.1. An example syntax block for a linked nodestring structure connection with a vertical flow specification follows.

! Structure block – user defined timeseries
! or Linked Nodestrings
Structure == Linked Nodestrings, location_ID_US, location_ID_DS
  Flux Function == Timeseries ! User specified flow time series
  Flux File == ..\model\csv\flow_timeseries.csv ! Time, Q time series
  Vertical Coordinate Type == Height ! {Elevation} |Depth | Height | Sigma
  Vertical Distribution File == ..\bc_dbase\S01_023_VDist.csv ! data_filepath
End Structure
