DRAINMOD Based Models

Field and Watershed Scale Models

The original DRAINMOD hydrology model has been modified to include sub-models on the fate and transport of nitrogen in the soil and salinity. The field hydrology and water quality models were also coupled with drainage network routing sub-models for watershed scale applications. Below are the models developed at the Biological and Agricultural Engineering Department at NCSU.

  • FLD&STRM (Konyha, 1989) – DRAINMOD based watershed scale Agricultural water management model.
  • DRAINLOB (McCarthy, 1990)- DRAINMOD based field scale forest hydrologic model.
  • DRAINMOD-S (Kandil, 1992)- DRAINMOD based field scale model for predicting salinity on arid/semi-arid lands.
  • DRAINWAT (Amatya, 1993) – DRAINLOB/FLD&STRM based watershed scale forest hydrologic model.
  • DRAINMOD-N (Breve, 1994) – DRAINMOD based field scale model for predicting Nitrogen from agricultural lands.
  • DRAINMOD-NII (Youssef, 2003) – DRAINMOD based field scale model for predicting Nitrogen
  • DRAINMOD-DUFLOW (Fernandez et al, 1997) – DRAINMOD field scale model linked to the Dutch model DUFLOW – a one-dimensional drainage canal routing model and water quality model based on the solution to the St Venant equation and ADR equation.
  • WATGIS (Fernandez et al, 1999) – A GIS-based lumped parameter watershed scale hydrology and water quality model. DRAINMOD and DRAINMOD-N models coupled with a delivery ratio routine to route drainage water and nutrients to the watershed outlet.
  • DRAINMOD-GIS (Fernandez et al, 2000) – A GIS-based lumped parameter watershed scale hydrology and water quality model. DRAINMOD/DRAINMOD-N models coupled with a simplified water and nutrient fate and transport sub-models.
  • DRAINMOD-W (Fernandez et al, 2001) – A watershed scale model based on DRAINMOD and DRAINMOD-N field scale sub-models with a finite difference canal routing model and a finite element solute transport sub-model.
