Landfallwahrsc
Landfallwahrsc is a term used in speculative geography and worldbuilding to describe a defined class of coastal transition events in which a region that was intermittently or permanently submerged attains a stable emergent landform that permits sustained terrestrial access from the sea. The concept focuses on the moment and process by which coastlines shift from marginal exposure to an enduring landfall, typically due to a combination of geological uplift, sediment deposition, isostatic rebound, and relative sea-level change.
Etymology and usage: The name combines the English word landfall with a constructed suffix -wahrsc, designed
Mechanisms and indicators: Landfallwahrsc events are characterized by measurable uplift rates, shoreline advance, increases in emergent
Applications: In worldbuilding and scenario planning, Landfallwahrsc helps to model future coastlines, resource distribution, and human
