Which description matches a surging breaker?

• A. Very steep slope, wave surges up beach
• B. Gentle slope, wave spills down front
• C. Steep slope, crest curls, strong impact
• D. Undertow

Answer: (A)

Surging breakers happen on very steep shorefaces. When the slope is so steep, the wave doesn’t form a curling crest; instead the energy surges up the beach in a sudden rush, with little or no breaking foam. That’s why the description “very steep slope, wave surges up beach” matches a surging breaker. The other patterns describe different breaker types: a gentle slope with the wave spilling forward is a spilling breaker; a steep slope with a curling crest and a strong impact is a plunging breaker; and undertow refers to backwash rather than the type of breaker. Understanding this helps you anticipate what the water will do near shore and plan a safer line.
