Steps for optimization of irrigation depth

The procedure consists of two steps: update run and optimization run.
Follwing example assumes decision of irrigation depth on 14 Jan, 2018 and irrigation interval is three or four days (last irrigation was carried out on 10 Jan).

Update run

  1. Modify irrigation file (e.g. Irrigation0110.csv) according to format of irrigation file.
  2. Download climatic data
    1. Run "climatic_data_downloader".
    2. Go to "Data" folder and move the output file (Metdata_on_18-1-14) to "MetData" folder.
  3. Run WASH_1D and load last "update case" (e.g. Update0110.in)
  4. Go to "Water Flow Information" form and change file for initial water content profile (Update0110_profile.csv).
  5. Change irrigation file (e.g.: Irrigation0110.csv ---> Irrigation0114.csv)
  6. Go to "Solute Transport Information" form and change file for initial solute concentration profile (Update0110_profile.csv)(It is automatically done).
  7. Go to "Atmospheric Boundary Condition" form and change meteorological condition file to "MetData_on_18-1-14.csv".
  8. Go to "Parameter of plant properties" form and add cumulative transpiration of last update run (divided by width of the region) to "initial cumulative Tr".
  9. Save case (Update0114.in) and execute.

Optimization run

  1. Download weather forecast
    1. Run "WeatherForecastDownloader".
    2. Go to "Data" folder and move the output file (Forecast0114.csv) to "MetData" folder.
  2. Run WASH_1D and load last optimization case (Optimization0110.in)
  3. Go to "Water Flow Information" form and change file for initial water content profile (Update0114_profile.csv).
  4. Go to "Solute Transport Information" form and change file for initial solute concentration profile (Update0114_profile.csv) (It is automatically done).
  5. Go to "Atmospheric Boundary Condition" form and change meteorological condition file to "Forecast0114.csv".
  6. Go to "Parameter of plant properties" form and add cumulative transpiration of last update run to "initial cumulative Tr".
  7. Save case changing case name (Optimization0114.in) and execute.

Important notes

  1. Space increments must be consistent throughout the season.
