Understanding subsurface hydrology of controlled drainage (drainage water management) and saturated buffers to optimize nutrient reduction goals in Illinois
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2024-05-01

Predicting Field Water Balance, Crop Yield, and the Economics of Drainage Under Various Cropping Systems Using Drainmod
<p>Subsurface drainage received considerable attention during the recent few years in South Dakota. While subsurface drainage is a widely accepted water management practice for increasing crop yield, research implicated tile drainage in surface and groundwater quality problems. Conservation …

Simulation of corn yield by a water management model for a Coastal Plain soil in Virginia
… measured water table depths from a subirrigation/controlled drainage site over a period of three years. Water table elevations predicted by the model were in good agreement with measured water table elevation data with an average deviation of 9.47 cm for the three years of record. The YIELD …

A Field-Scale Study of Controlled Tile Drainage and a Pond-Wetland to Attenuate Nutrients from Agricultural Overland Runoff and Subsurface Drainage on a Farmer-Operated Seed Farm in Saint-Isidore, ON
Agricultural runoff and drainage are significant contributors to the deterioration of water quality in receiving water bodies. Ponds and constructed wetlands are proven treatment systems that can remove nutrients and reduce peak flow. A combined controlled drainage structure (CDS), free drainage …

An investigation of liquefied shear strength using novel centrifuge tests, direct simple shear tests, and field case histories
… shear (DSS) laboratory element tests under controlled drainage conditions performed were used to characterize the critical state properties of three nonplastic soils, including the one used in the centrifuge modeling. In addition, various strain rates were used in DSS tests to supplement the …
