SMS:CMS-Wave Monitoring Station Output File

From XMS Wiki
Jump to: navigation, search

CMS-Wave can include monitoring stations that will extract the calculated data values, including the wave height, period and direction. The extracted values are stored in the CMS-Wave monitoring station output file (selhts.out) generated during the model run. This file will only be created 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 file uses a fifteen column format with values described in the table below:

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