Emergence Setting and Hydrology
Discrete source flow gushes from a cliff wall of a perched, unconfined aquifer.
For Example: Thunder River, Grand Canyon, AZ
Gushet springs emerge from discreet sources in cliff faces. They were proposed as a unique sphere of discharge by Springer et al. (2008). They typically discharge from perched, unconfined aquifers, often along fractures. Gushets often support madicolous habitat, thin sheets of water flowing over rock faces (Hynes 1970). Gushet springs frequently contain many different microhabitats, supporting diverse ecosystems. Although they occur primarily in areas dominated with steep escarpments, such as Grand Canyon, they are also found in regions with more modest topographic relief.
