Answer to Question 1

Dredging is commonly used. At Santa Barbara, a dredge works year round to remove sand from a
growing spit at the mouth of the harbor.

Answer to Question 2

The relatively small first wave was mistakenly thought to be the extent of the danger by some
residents. Many returned home prematurely and then fell victim to the much larger waves that
followed. Sadly for those who died, it was the third wave that was the biggest.
