Abstract

Stationary and trolling methods in measuring flow using flowmeter were adopted to investigate the hydraulic connectivity of fractures and to evaluate the applicability of the measurement methods. Stationary method was useful for identifying the inflow and outflow patterns in the measured section, which enabled us to analyze the hydraulic connectivity of fractures between the wells. Trolling method failed to find the inflow and outflow patterns in the well, but was very effective for locating the conductive fractures. Measuring flow in the borehole by both stationary and trolling methods was found to be very efficient for identifying conductive fractures and their hydraulic connectivity in fractured rock aquifer.

공내 유량측정기의 고정식 및 이동식 측정방법을 이용하여 암반대수층에서의 절리의 수리적 연결성 및 두 측정방법의 적용성을 검토하였다. 고정식 측정방법의 경우 측정구간에서의 지하수의 유출 및 유입을 파악할 수 있어, 관정사이의 수리적 연결성을 해석하는데 매우 유용하였다. 이동식 측정방법의 경우 유량측정기의 이동속도로 인해 지하수의 유출 및 유입 경향을 파악할 수 없었으나, 지하수 유출 및 유입이 일어나는 절리의 정확한 위치를 찾는데 매우 유용하였다. 두 측정방법을 동시에 사용하는 것이 지하수 유동절리의 위치 및 수리적 연결성을 파악하는데 더 효율적인 것으로 나타났다.
