Abstract

We study changes of water discharge from rock to a tunnel in relation to surface infiltration, near Bedrichov in the Jizera mountains. New automatic measurements of flow rate at several points in the tunnel followed the previous 5 years of manual measurement and were extended with the surface water infiltration record. We explain different types of reaction: a very quick and strong inflow rise in the shallow permeable part, a gradual change with retardation in the deeper hard rock, or a stable inflow not related to the infiltration.
