Check Files 2d fc
Contains information on the cell sides (U and V points) that have a flow constriction object applied. This contains information on the processed elevations, blockages and form loss values applied at the cell side. Note that this only applies for the older 2d_fc_ layers "Read GIS FC == ". The newer Flow Constriction Shape (2d_fcsh) and Layered Flow Constriction Shapes (2d_lfcsh) have separate check files.
Attributes of _fc_check
|Attribute Name||Attribute Description|
|Type||The flow constriction type as described in the TUFLOW manual.|
|Invert||The ground level of the z point.|
|Obvert_or_BC_Height|| This attribute is dependent on the FC type:|
|u_width_factor||The cell width factor applied in the U direction|
|v_width_factor||The cell width factor applied in the V direction|
|Add_form_loss||Additional Form Loss coefficient which is applied.|
|Mannings_n||For "BC" type constrictions the Manning's n value. For "BD" and "FD" this is used to specify additional roughness as per the TUFLOW manual.|
|No_walls_or_neg_width|| Only used for "BC" type constrictions. Number of vertical walls per grid cell. If set to zero (between 0.001 and 0.001) one vertical wall per cell is used.
Alternatively, and more easily, specify the width of one culvert in metres by using a negative value. For example, if the culverts are 1.8m wide, enter a value of -1.8 and the number of vertical walls per cell is automatically calculated.
|Blocked_sides|| Indicates whether any of the walls of the constricted cell(s) are blocked off (ie. no flow across/through the side wall). One or more of the following letters in any order with in the field to indicated which wall(s) are blocked:
|Comment||Comment as specified on the input layer.|
