Leaky Sewers Hydraulically Disconnect from Groundwater: A Proof‐of‐Concept

Groundwater, EarlyView.
In this study, we newly demonstrate that leaky pipes can become hydraulically disconnected from the underlying groundwater—a phenomenon analogous to river–groundwater interactions. Through numerical modeling, we show that, as the groundwater table declines, the leakage flux from the pipe (in absolute terms) initially increases until a critical depth ...
