The OUTPUT_GATE table is used by both HYDRO to
specify output requests at a gate. Output is
HEC-DSS or text format.
The table specifies the name for output request, as well as the
location, variable being output, time aggregation and destination file.
- Name of the output request. This is the identifier of the table and will
be used in the B_PART of the output if it is in DSS format. It can be the same as the
gate name but it doesn't have to be. Avoid using VARIABLE inside this name -- this causes
redundancy in the output and the layering won't work correctly.
- Name of the gate at which output is requested.
- Name of the gate device, if applicable. You can request operational or physical data
from a device as well as flow. You can also request
some gate output (install,flow) that is not linked to a particular device. In this case, the field should be set
- Model variable to be output. From a device you can request some physical data
(width, height, elev),
operational data (op_to_node, op_from_node, position ) or flow oriented from water body to node.
From a gate with device=none you can request the variables install, or total flow oriented from water body to node.
- Time Interval of the output. Can be any DSS-compliant
interval with a unit that is not calendar dependent (MIN, HOUR, DAY). This is a
departure from previous versions of DSM2, which offered monthly output.
- Period aggregation performed to convert the model time step
into the time interval of the output. May be INST or AVE, but AVE can be meaningless
for a lot of gate variables.
- Name of the output file where the data will be stored. If the extension .txt is given,
the output is automatically in text format. If a .dss extension is used, output is
in HEC-DSS format.
- NAME, VARIABLE
- Parent Table:
- Table is parent
- Include Block:
- Initially, the thing that is hard to get about gate output is the flow orientation. The output for the gate
is oriented with the gate, which may or may not be in the upstream-downstream direction
