Onsand

Onsand is a fictional coastal locality commonly used in education, simulations, and coastal engineering exercises. It serves as a neutral reference point to illustrate shoreline processes without tying analysis to a real-world site.

Geography and environment

In standard scenarios, Onsand features a low-lying sandy coastline with a broad beach, dune field, and a small sheltered harbor. The shoreline is subject to regular wave action, seasonal storms, and sediment exchange with nearshore bars. Vegetation on the dunes plays a role in stabilizing the sand and shaping long-term evolution of the beach profile. Climate within the assumed model ranges from temperate to subtropical, with typical annual rainfall supporting dune ecosystems.

Human activity and management

The fictional community surrounding Onsand often includes a coastal road, a modest fishing hamlet, and a pier or harbor infrastructure. Studies using Onsand examine dune restoration, beach nourishment, and flood defense design. Scenarios may compare passive erosion against engineered stabilization, assess the impacts of storm events, and evaluate habitat considerations for coastal species.

Purpose and usage

The name Onsand is a synthetic label chosen for consistency across exercises, datasets, and software tools. It is not associated with a real location. By providing a representative setting, Onsand allows educators, researchers, and planners to discuss coastal risk, sediment dynamics, and adaptation strategies in a clear, controlled context.
