F.P. Haeni 1986 Seismic refraction studies were conducted over unconfined glacial aquifers in New England to determine: 1) depth of the underlying bedrock; 2) depth of the water table; 3) saturated thickness of the aquifer in areas not accessible to heavy drilling equipment; 4) areas where thick, unsaturated sediments overlie thickly saturated parts of the aquifer; and 5) locations of test holes and type of drilling equipment needed. These data were used in groundwater models and provided parameter values that required few adjustments during calibration. -from Author application/pdf 10.1190/1.1442083 en GeoScienceWorld Application of seismic refraction methods in groundwater modeling studies in New England (USA) article
