Interest AreasDr. Helmers's research interests are in the areas of water management and water quality, specifically non-point source pollution, drainage, in-field performance of vegetative filters, and the impact of crop and animal production systems on Iowa's water resources. In addition, Dr. Helmers has research interests in monitoring and modeling watershed hydrology, including the hydrologic response of watersheds to land-use changes. Much of his present research focuses on subsurface drainage and the impacts of subsurface drainage on hydrology and water quality in agricultural areas. Previous research focused on multidimensional overland flow of water in vegetative filters. The study included a comparison of measured and modeled overland fl ow to evaluate the sediment-trapping efficiency of vegetative filters.
