Geophysical investigations in a losing stream valley, Phelps County, Missouri

Abstract

“Discrete recharge of a karst aquifer occurs from a losing portion of the Dry Fork River, Phelps County, Missouri, as shown by refraction seismology, self-potential surveys, and dye tracing results. The discrete losing zone is best defined by a streaming potential anomaly of -15 millivolts. Water moves from the river, through coarse alluvial deposits, into fracture-controlled solution features in the underlying bedrock, as determined from the shape of the SP anomaly.

The average hydraulic conductivity of the riverbed deposits is 0.10 m/s as determined by dye tracing. In the vicinity of the losing zone, a vertical flow path into bedrock solutional features is preferred over the downstream path to lower portions of the stream channel. In the recharge area, bedrock underlies the unconsolidated alluvium at depths of 9 to 12 meters”--Abstract, page ii.
