Hydrologic impacts of subsurface drainage at the field scale: Climate, landscape and anthropogenic controls

Installation of subsurface drainage systems is one of the most common changes to an agricultural landscape. The hydrologic impacts that these changes have on the landscape is still widely uknown. We explore the impact of drainage systems using a field-scale model and rainfall and soils data for Iowa. Our objective is to understand how climate, landscape and human activity influence the movement of water at the field scale.
