Summary

This page describes the Hydrotel module adapter, its functions, and provides an example for configuring a Hydrotel run in FEWS.

The pre-adapter converts netcdf file exported by FEWS:

  • netcdf run file (given to the preadpter as input)
  • meteo.nc (required)
  • corrections.nc (required)
  • debit.nc (optional)

Furthermore, the pre-adapter writes log messages to a log file called hydrotel_preadapter.log.

The post-adapter converts all *.csv files to one netcdf file "resultats.nc" which names are present in the "sortiesHydrotel" ; separated string property value.The values are weighted by columns specified in "info/uhrh_amont.txt".

It also copies the state files with a timestamp in the filename after start time to the output states directoy

This adapter is specifically created and tested for a time step of 3 hours, some extra changes will be necessary to make it compatible with other time steps.

Pre-adapter

Model pre-adapter for running a Hydrotel model from Delft-FEWS.

Class name: nl.deltares.hydrotel.HydrotelPreAdapter

For the source code see HydrotelPreAdapter 

The pre-adapter converts netcdf file exported by FEWS:

The Hydrotel PreAdapter will look for property "sortiesHydrotel" in netcdf run file and expects a ; separated string with all the the output parameters that are desired for Hydrotel.

It will write the output parameter to output.csv with a ; and a 1 behind them. For an example see:  hydrotel output.csv

It will also write start and end times to simulation.csv:

'DATE DEBUT' - start date
'DATE FIN' - end date + 3 h
'ECRITURE ETAT FONTE NEIGE' - start date + 1 day
'ECRITURE ETAT BILAN VERTICAL' - start date + 1 day
'ECRITURE ETAT RUISSELEMENT SURFACE' - start date + 1 day
'ECRITURE ETAT ACHEMINEMENT RIVIERE' - start date + 1 day

But if property "sauvegardeEtatFinSimulation" is set to true in netcdf run file, it will write the end date instead of start date + 1 day

For an example see: Simulation.csv

Notes for users

  • For all files that are written by this adapter, if the file to be written already exists, then it will be overwritten.
  • The preadapter writes log messages to a log file called hydrotel_preadapter.log.
  • This program uses the information in the specified netcdf run file as input and uses this information to do the following actions:

System requirements

  • This program needs Java version 1.8 or higher.
  • This program needs the following Java libraries:
    • castor-0.9.5.jar
    • commons-httpclient-3.0.1.jar
    • Delft_NetCDF_Util.jar
    • Delft_TestSupport.jar
    • Delft_Util.jar
    • joda-time-2.8.1.jar
    • junit-4.8.2.jar
    • log4j-1.2.14.jar
    • netcdf-4.6.3.jar

    • slf4j-log4j12-1.5.6.jar
    • xercesImpl.jar

Hydrotel post-adapter

Class name: nl.deltares.hydrotel.HydrotelPostAdapter

The post-adapter converts all *.csv files to one netcdf file "resultats.nc" which names are present in the "sortiesHydrotel" ; separated string property value.

By default the values are weighted by columns specified in "info/uhrh_amont.txt" and all combined to 1 value per time step and parameter.

But if the property "importerValeursExutoireSeulement" is present in the run_info file and has values "false" all values from the csv file are written to the "resultats.nc" as unique locations and not being weighted. For example see "resultats_unique_locations.nc".

When the integer property "resultsOffset" is present it add the value in minutes to the output times.

It also copies the state files with a timestamp in the filename after start time to the output states directoy when boolean property "sauvegardeEtats" is set to "true" in the netcdf run info file.
