Abstract
AbstractAn automatic seepage meter using a heat pulse method was developed to obtain a continuous measurement of ground‐water seepage rates. According to calibrations of the automatic seepage meter fitted with a 50 cm diameter collection funnel, seepage rates from 2 X 10‐5 to 5 X 10‐4 cm/sec can be obtained by measuring the time when the temperature as measured by a thermistor peaks after applying a heat pulse. The automatic seepage meter was used to measure continuous seepage rates into Lake Biwa, Japan. The ground‐water seepage rate measured by the automatic seepage meter in Lake Biwa changed by six times within 12 hours. The automatic seepage meter is useful for surface‐/ground‐water studies, because a continuous seepage rate can be obtained without errors caused by the resistance of a collection bag to water flow.
