A coupled SWAT-MODFLOW model to evaluate the effects of management practices on surface-groundwaterPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: 2015 ASABE Annual International Meeting 152188742.(doi:10.13031/aim.20152188742)Authors: Xiaojing Ni, Prem B. Parajuli Keywords: Watershed Modeling, Groundwater Modeling, SWAT, MODFLOW, Hydrology Abstract. Water quality pollutants, which may be generated due to point and non-point sources (e.g. agricultural activities), can affect both surface water and groundwater resources. The objective of this study is to assess the effects of management practices on surface water and groundwater using Soil and Water Assessment Tool (SWAT) and MODFLOW models in the Big Sunflower River Watershed (BSRW) in Mississippi. The MODFLOW model, was used to simulate groundwater flow with boundary, recharge and HRUs calculated from SWAT model. A coupled SWAT-MODFLOW model was applied to evaluate the water quality and quantity effects due to different agricultural management practices. The results of this study showed that more interactions between surface water and groundwater exist in the downstream area of watershed. Different management practices will be applied to coupled SWAT-MODFLOW model to evaluate the effects of water quantity on surface-groundwater. (Download PDF) (Export to EndNotes)
