Abstract.This article presents the development of a drainage-climate interface that incorporates climatological data, crop drainage requirements, and drainage theory into a procedure for characterizing drainage system response under different climate scenarios. The drainage-climate interface is suitable for assessing potential county-level impacts of climate change on crop production, soil hydrology and subsequently on subsurface drainage design. Climate model projections from two general circulation models (GCMs), namely CCSM4 (Community Climate System Model) and MIROC5 (Model for Interdisciplinary Research on Climate), were used to create the climatological database for the drainage-climate interface. DRAINMOD was integrated into the Visual Basic for Applications (VBA) portion of the interface to simulate the performance of subsurface drainage systems in Illinois for the near future (2040 to 2069) and the far future (2070 to 2099) periods. Case studies were developed with the interface for Adams and Champaign Counties in Illinois for their predominant soil types. Hydrologic simulations from the interface were used to determine the optimal depth and spacing of tile drains that maximize crop yield for corn and soybean during the mid and late 21st century. Drainage water management (DWM) was incorporated into the drainage-climate interface to investigate the potential of DWM in the future climate scenarios to maintain water quality, reduce nutrient losses and minimize pollutant loading from drained fields by controlling the timing and amount of water discharged from agricultural drainage systems. Results from DRAINMOD simulations with MIROC5 show a significant decline in crop yield due to extreme heat stress. Corn yield in the future showed a severe reduction while the yield for soybean demonstrated a gradual decline over the years. DWM had only a minimal effect on future crop yield trends. The drainage-climate interface simulated subsurface drainage conditions and made evident the consequences of environmental conditions on crop physiological processes under scenarios of climate change predicted by MIROC5. Keywords: Agricultural system models, Climate change impacts, Drainage-climate interface, Drainage water management, Subsurface drainage, Tile drain depth, Tile drain spacing.

Nitrate loadings from agricultural drainage to surface water resources cause’s serious water quality concerns in many parts of the world. Denitrification bioreactors are suitable option for removing nitrate from agricultural drainage water. The objectives of this study was to investigate the effect of different hydraulic cross sections of denitrification beds on the amount of effluent EC. In this study, three denitrification beds were constructed with a semicircular, triangle and a rectangle cross sections, filled with wood chips of beech tree. Samples were taken from the outlets of all three beds at a depth at 25 and 50 cm from the bottom of the bed for two months. EC of the samples was meassured using EC-meter. After determining the EC of the samples, data were analyzed by T-test and Univariate tests. The results showed that the shape of the cross-section of the denitrification beds and the saturation depth had a significant effect on EC and the amount of EC of the outflow was increased.
