WebApr 13, 2024 · Termed vortex ripples by Bagnold & Taylor (Reference Bagnold and Taylor 1946), these ripples are characterized by the prominence of spanwise vortices in the overlying flow near the ripple surface, which are periodically formed on the lee-side ripple flank and ejected into the water column from the ripple crest. WebGeysers are hot springs that intermittently spout a column of hot water and steam into the air. This action is caused by the water in deep conduits beneath a geyser approaching or reaching the boiling point.At 300 metres (about 1,000 feet) below the surface, the boiling point of water increases to approximately 230 °C (450 °F) because of the increased …
