How to create MOHID timeseries outputs

From MohidWiki

Jump to: navigation, search

In this tutorial we will continue to develop the previously used test-case and we will configure the model so it returns a time serie with the water level at the coordinates of our choice on the domain. These time series can then be compared against tidal stations experimental measurements.

Step 1 - Define the data-acquisition stations

Run Google Earth

Make sure you have Google Earth correctly configured!!

  • With Google earth, choose the locations where there are tidal stations

Repeat the process for every tidal station.

  • Save the google earth placemarks as a kml file

Run Kml2Mohid

  • Successfully run Kml2Mohid program to convert the google earth placemarks into a points file.

  • Sample points (.xyz) file. This what the resulting file should look like:
-9.317324064466845 38.67641458263528 0

Step 2 - Create time serie stations with Mohid GIS

Import the xyz file containing the tidal stations

  • In Mohid GIS, from the Project menu, select open

  • Select the folder, select the saved GIS project, then click on Open:

  • Here's what the opened GIS project should look like

  • From the Data Items menu select Add Data Item

  • ????

  • Drag'n drop the points layer to the top, then right-click on it, then select Properties

  • Set the pixel size to 5, then select Settings

  • Select a color and a pixel size for the points.

  • Check that the point is well where it should be on the grid

Create the MOHID time series

  • From the Tools menu, select Create Grid Time Series

  • Select the grid data layer, select the correct xyz layer, define the folder and a new filename for the time series configuration file, define a 10 minute period outputs interval, then click on Ok.

  • Click Ok upon success!

  • Here's a typical time series configuration file

DT_OUTPUT_TIME                :  600
MAX_BUFFER_SIZE               :  10000

Based on XYZ file             : D:\Users\Soussou\GeneralData\kml2gis\

LOCALIZATION_J                :  127
LOCALIZATION_K                :  1
CENTER_CELL_X                 : -9.31735
CENTER_CELL_Y                 :  38.67645
ORIGINAL_X                    : -9.317324
ORIGINAL_Y                    :  38.67641

Step 3 - Configure the model so as to output time series results

  • Open the GUI project

  • Select the MOHID project

  • Open the Hydrodynamic module

  • Add the following lines to the hydrodynamic configuration file, then save and close
TIME_SERIE             : 1
TIME_SERIE_LOCATION    : D:\Users\Soussou\GeneralData\TimeSeries\StLouisTimeSeries.dat

Step 4 - Run the model again and inspect the time-serie results

Run the model

If all is correctly configured, and all the input files are double-checked, we can hopefully start running our model!

  • Select Tools from menu, then Launch Mohid...

  • Select the Run_1, then select Run Mohid, then select Launch after Ok, then click on Ok

  • Supervise the screen-outputs to check for any error, or to simply read the estimated end time of simulation

Inspect the time-serie results

  • Click on the HDF analysis mode icon, then double-click on any new .srh file, which is a time serie result from the model that can be opened with the Time Series Editor program that comes bundled with the MOHID suite.

  • Select elevation then click on Ok

  • Select the .srh file present, then click on Draw Chart

  • Inspect and admire the plotted time serie results :)
