coastal hazards

Synonyms

chronic costal hazards

Definition

Chronic hazards are those hazards that constantly affect the coast: beach, dune, and bluff erosion; slides, slumps, and gradual weathering of sea cliffs; and flooding of low-lying areas during major storms. Some areas have periodic sand buildup as well. Chronic hazards come from winter storms, associated storm surges, and wave setup; strong near shore currents; high winds, rain, runoff, and associated lowland flooding; and elevated sea levels caused by seasonal effects and periodic El Ninos.(oregongeology.org)
