SMS:CMS-Wave Monitoring Station Output File

CMS-Flow can extract the calculated wave height, period and direction information from the monitoring station output file (selhts.out) for a single station. This file will only be creaed if a monitoring station data is specified in the control file.

In SMS, monitoring stations are created as a cell attribute in the Cartesian grid.

File format

The selhts.out uses a fifteen column format as shown in the table below:

Column Number	Value
1	Spectrum label (or timestamp)
2	I index in Cartesian (i,j) or ij index in Quad-tree mesh
3	J index in Cartesian (i,j) or 0 (dummy) in Quad-tree mesh
4	Significant wave height (m)
5	Spectral peak wave period (sec)
6	Mean wave direction (deg, local coordinate system)
7	Swell height (m)
8	Swell wave period (sec)
9	Swell direction (deg)
10	Local-generated wave height (m)
11	Local-generated wave period (sec)
12	local-generated wave direction (deg)
13	Wave breaking index (non-zero for breaking)
14	Max water elevation mark (m), include wave run-up if calculated
15	Flow discharge rate (m*m/sec) at structure cells if calculated
