Development of DRAINMOD-based VBA model for evaluating drainage system response
This study presents the development of a VBA (Visual Basic for Applications) model that incorporates climatological data, crop drainage requirements and drainage theory into a viable design procedure. The design of subsurface drainage systems is affected by climatic variables such as temperature …

A Drainmod-Based Decision Support System (Dss) for Drainage and Water Quality in Illinois
The DRAINMOD-based Decision Support System for Drainage in Illinois was shown to be a useful tool for users of various skill levels. Increased soil database resources along with updating the DRAINMOD-N component were suggested to further increase the utility of the DSS.

Modeling Water Quantity and Quality on Tile Drained Watersheds With a GIS Coupled DRAINMOD
The DRAINMOD-GIS model was demonstrated to be a useful tool in addressing spatial variability in tile drained fields and watersheds. Recommendations were given to improve the both the model interface and DRAINMOD.

Predicting Field Water Balance, Crop Yield, and the Economics of Drainage Under Various Cropping Systems Using Drainmod
… bulk density, and rainfall) collection. DRAINMOD was used with the baseline data to quantify the long-term hydrologic impacts of subsurface tile drainage on field water balance for different drainage conditions (conventional drainage, controlled drainage, and undrained condition) and …

Modeling of water table profile for a subirrigation system and evaluation of reliability of drainmod for the Lower Fraser Valley
… Columbia under different water regimes with DRAINMOD and the results were compared with data obtained from conventional subsurface drainage and subirrigation field experiment at Boundary Bay in the Lower Fraser Valley. Predicted and measured water table depth were compared for 4 years (1985, …

Simulation of corn yield by a water management model for a Coastal Plain soil in Virginia
DRAINMOD, a water management simulation model for artificially-drained soils, was evaluated for a Virginia Coastal Plain soil by comparing predicted and measured water table depths from a subirrigation/controlled drainage site over a period of three years. Water table elevations predicted by the …

Impact of Subsurface Drainage on Water Yield for Typical Soil and Weather in Eastern South Dakota
… Long-term simulations were performed in DRAINMOD, a field scale deterministic process based hydrological model, to quantify each component involved in the water balance. The hydrologic outputs (daily, monthly, and yearly) of DRAINMOD were used to determine the impact of subsurface …

Effect of bioenergy crops and fast growing trees on hydrology and water quality in the Little Vermilion River Watershed
… 615) with the new tile drainage routine (DRAINMOD routine) and improved perennial grass and tree growth simulation was used to model long-term annual biomass yields, flow, tile flow, sediment load, total nitrogen, nitrate load in flow, nitrate in tile flow, soluble nitrogen, organic …
