The Delta Water Management Research Unit focuses on preserving the quality and availability of water resources used in agricultural environments, particularly in the small, rural farms that predominate the Lower Mississippi River Delta area. This includes investigations into the impact of agricultural byproducts used as soil amendments. In order to accomplish project goals, specific objectives are to 1) Conduct hydrological system studies to measure, model and predict the impact of current and innovative farming practices and associated ground and surface water withdrawals on water availability and quality; and 2) Develop economical and environmentally sound irrigation and drainage management tools, practices, and technologies that conserve water and protect regional water resources and supplies.
