Boundary conditions can be applied:

Spatially (typically metrological conditions and/or wave fields)

Along a nodestring (external boundaries such as water levels or flows)
o

The [id] value is the nodestring identifier included in the mesh geometry file (see
Section 4.2.1.1)
As a point source (within a single cell such as an outfall discharge)
o
The [xid], [yid] values are the coordinates of the source location within the model
domain.

BC Header == <Header1,Header2,...>
(Optional)
BC block command that allows the user to specify the .csv input file column headers or netCDF file
variable names (thereby overriding the defaults in described in Table 4-3and Table 4-4). This
command should immediately follow a BC command.
For example, the following lines apply a cell inflow (QC boundary condition type) at the cell which
lies at the x,y coordinate 1025.5, 950.5. It looks in the specified .csv file for columns Time,
