# Output:WMS Hydrograph File

GSSHA has the capability to write the outlet and the internal location hydrographs to a file format readable by WMS v7.0 and higher. This is specified by including the **WMS_HYDRO** project card and the name of the file to be written to. The WMS hydrograph file is generated post-process, at the end of a GSSHA run. The file has the following format:

GEISSHA_WMS_HYDROGRAPH_FILE [Number of internal hydrographs {N}] [start date (YYYYMMDD)] [start time (2400)] [time step interval, in seconds] [number of hydrograph ordinates {M}] [first node/link pair] [second node/link pair] … [Nth node/link pair] [outlet hydr. ord.–1] [outlet hydr. ord.–2] … [outlet hydr. ord.–10] [outlet hydr. ord.–11] [outlet hydr. ord.–12] … [outlet hydr. ord.–20] [outlet hydr. ord.–21] [outlet hydr. ord.–22] … [outlet hydr. ord.–30] … [outlet hydr. ord.–M-9] [outlet hydr. ord.–M-8] … [outlet hydr. ord.–M] [internal hydr1 – 1] [internal hydr1 – 2] … [internal hydr1 – 10] [internal hydr1 – 11] [internal hydr1 – 12] … [internal hydr1 – 20] [internal hydr1 – 21] [internal hydr1 – 22] … [internal hydr1 – 30] … [internal hydr1 – M-9] [internal hydr1 – M-8] … [internal hydr1 – M] [internal hydr2 – 1] [internal hydr2 – 2] … [internal hydr2 – 10] [internal hydr2 – 11] [internal hydr2 – 12] … [internal hydr2 – 20] [internal hydr2 – 21] [internal hydr2 – 22] … [internal hydr2 – 30] … [internal hydr2 – M-9] [internal hydr2 – M-8] … [internal hydr2 – M] … [internal hydrN – 1] [internal hydrN – 2] … [internal hydrN – 10] [internal hydrN – 11] [internal hydrN – 12] … [internal hydrN – 20] [internal hydrN – 21] [internal hydrN – 22] … [internal hydrN – 30] … [internal hydrN – M-9] [internal hydrN – M-8] … [internal hydrN – M]

The hydrograph ordinates are arranged 10 to a row, with each new hydrograph starting on a new line. If the number of hydrograph ordinates is not evenly divisible by 10 then the rest of the last line of ordinates for the hydrograph is left blank. The node-link pairs are arranged in the same order as the input and output hydrograph location files. The hydrograph data follow the same order, with the hydrograph data for the outlet being first and the internal location hydrographs following in order.
