Check Files 1d nwk N

This GIS layer contains information on the 1D nodes for the simulation.
The _1d_nwk_C_check file contains information on the 1D channels.

Attributes of nwk_N_check

Attribute Name	Attribute Description
ID	The node ID.
Type	The node type, the options are: Node: A standard 1D node MH: A manhole node
Ignore	"T" (true) if the node has been set to ignore in the input 1d_nwk file, "F" (false) otherwise.
Bed_Level	The bed or lowest elevation at the node.
ANA	Any additional nodal area that has been added at the node (value in square metres or square feet).
Conn_1D_2D	The 1D/2D connection method (if used) otherwise set to "----". See the TUFLOW Manual for a list of 1D/2D connection methods.
Conn_Width	The connection width of the 1D/2D connection, this is used for determining how many 2D cells to connect to.
R1	Not used.
R2	Not used.
R3	Not used.
i_1d_layer	The index to the input layer that has created the manhole. For example an i_1d_layer value of 2 would be the 2nd input layer (1d_nwk_M05_pits_001_P) below. Read GIS Network == 1d_nwk_M05_pipes_001_L Read GIS Network == 1d_nwk_M05_pits_001_P
No_Channels	Number of channels the node is connected to.
Pit_Connected	"Y" (Yes) if the node has a 1D/2D connection, "N" (No) if not.
