Book Description
Agricultural tile drainage is an integral part of Iowa's landscape, with nearly 30% of Iowa's cropland being drained (Schilling & Helmers, 2008). Tile drainage allows for efficient crop production in Iowa's nutrient rich soils by removing excess water from frequently inundated fields through subsurface pipe networks. These tile systems are suspected of altering the hydrologic regime of Iowa, but the extent of the problem remains unknown. A literature review is performed to assess the current understanding of tile drainage and to help create a framework of analysis to address this problem. The deterministic field-scale model DRAINMOD is used in both a field and catchment scale analysis of the hydrologic impacts of tile drainage in conditions typical to Iowa. The field-scale study explores the influence of soil type, surface storage, rainfall characteristics, and drainage spacing on how tiling impacts the hydrologic response. A range of metrics, including the mean annual peak flow, flow duration curves, and the Richard Baker Flashiness Index are used for the analysis.
