A research project for the Florida Institute of Phosphate Research sought to develop an easy-to-apply integrated surface drainage model, HSPF, and groundwater model, MODFLOW, with a geographic information system, GIS, for long-term hydrological management of mine reclamation lands. Details of the model objectives and formulation can be found in other papers. The emphasis of this paper is on the surface infiltration to water table recharge process, parameter definition and calibration that is a vital part of linked continuous surface-water/groundwater hydrological modeling. Problems with the HSPF infiltration algorithm are discussed, and alternative physical parameter definitions are presented.
