  1. III II I Site Description • Very active morphodynamics – risk for beach users • I. Generation of Ness pole & • NE migration. • II. As Ness pole disintegrates, • it forms offshore sandbanks • which migrate onshore. • III. Onshore-migrating shoals • attach to shore.

  3. Expected results • Simulations for: • A range of wave heights and directions • Spring and neap variations • A range of river discharge • Characterise risks and produce a chart explaining them • Generate a risk map template for the manager to modify.
