Floodtides
Floodtides occur when high tides coincide with other flood-inducing conditions, amplifying the inundation of coastal areas. The phenomenon can result from a combination of astronomical tide, storm surge, atmospheric pressure changes, and hydrological inputs. When spring tides, which are the highest tides that happen during the full and new moons, coincidentally align with a storm or rapid snowmelt, the water levels exceed normal tidal ranges by several meters.
The greatest risk from floodtides is the expansion of the water’s reach inland, often overwhelming natural
Floodtide events are recorded and monitored by tidal gauges and storm surge models. Management strategies involve
Studies indicate that sea level rise may increase the frequency and severity of floodtides by raising the
