A STUDY ON RESPONSIVENESS OF VERTICAL PROFILE OF ELECTRICAL CONDUCTIVITY OF UNDERFLOW WATER NEAE TEE RIVER LEVEE DURING A FLOOD

Abstract

Continuous observation of electrical conductivity in two bore holes located in close proximity to a river Levee was conducted. Water level of the bore holes and the neighboring river were observed. The Chain-Array detection was also performed to examine the observed characteristics of the electrical conductivity. Vertical profiles of the electrical conductivity showed remarkable responsiveness for the floods. Vibration of the electrical conductivity was also observed. The vibration of the electrical conductivity disappeared during a flood. Characteristics of the electrical conductivity indicate the effectiveness of continuous monitoring of the electrical conductivity of underflow water in close proximity to a river.
