Agro-Hydrological Modeling in dry areas

September 18, 2016

A two day training on Agro-Hydrological Modeling in dry areas was held in Amman, Jordan during August 10-11, 2016. The training was offered under the auspices of the WLI’s Modeling Thematic Group, and by Drs. Biju George and Usman Khalid, ICARDA scientists working in the field. The training was designed to enhance researchers’ capacity in:

  • Salt and water movement in vadose zone by Hydrus-1D, including estimating input parameter for Hydrus e.g., FAO-56 dual crop coefficient approach to estimate evaporation and transpiration,
  • Approaches to calibrate and validate Hydrus-1D,
  • Estimating reference evapotranspiration by CROPWAT 8.0 using Penman-Monteith approach, and

Using CROPWAT 8.0 to calculate crop-specific evapotranspiration, irrigation schedule and net and gross water requirements under different cropping patterns.

At the end of the training the targeted researchers from Egypt, Iraq, Lebanon, Tunisia, and Yemen were able to calculate the crop water requirements, decide when and how much to irrigate, implement Hydrus-1D for saline and non-saline soils for maximizing net profits, and to plan deficit irrigation schedule based on salt and water movement in vadose zone using their own data. The training was also successful in creating great potential for regional collaborative research.
