Measurement of Groundwater Flow Velocity at CHASNUPP Site Using Radiotracer Technique

摘要

Radioactive tracer, Iodine-131, was used to determine the groundwater flow velocity at CHASNUPP Site by applying multi-well technique. During the experiment, the water table was monitored in the detection wells and the groundwater regime was found unstable due to fluctuations in the water level of Chashma-Jhelum Link Canal flowing nearby the area under study. The groundwater flow velocity was estimated to be about 4.8 cm per day under the prevailing conditions.
