What is a resurgent spring?

A resurgent spring refers to a type of spring that forms when groundwater flows to the surface due to pressure, often emerging from a hillside or cliff. This phenomenon typically occurs in karst landscapes, where soluble rock like limestone has been eroded to create underground channels. The term can also imply a seasonal revival of flora and fauna as ecosystems rejuvenate during springtime. Overall, resurgent springs are significant hydrological features that contribute to local water supplies and biodiversity.
