DRAINMOD based 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.

 

Please send us a note if there are other DRAINMOD based models (field or watershed scale) developed in various universities or research organizations.
