Abstract
A simple method that enables calculation of the vertical specific discharge across the water sediment interface of a lake was applied in Lake Kinneret, Israel. It is based on groundwater levels measured from above the lake surface. The measurements are performed in piezometer nests installed in the bottom sediment of the lake. The piezometers are initially calibrated by a seepage meter to calculate the in situ vertical hydraulic conductivity (Kv) of the sediment. In one study site, the mean Kv (within a 95% confidence interval) was calculated to be 7.9 ± 3.7 × 10-7 cm/sec. Measurements conducted over an eight month period show flow from the sediment into the lake and a vertical specific discharge varying from 2 to 10 cm/yr.
