Alternatives/complements To Nourishment
Nourishment is not the only technique used to address eroding beaches. Others can be used singly or in combination with nourishment, driven by economic, environmental, and political considerations.
Human activities such as dam construction can interfere with natural sediment flows (thereby reducing riverine sediment sources.) Construction of littoral barriers such as jetties and deepening of inlets can prevent longshore sediment transport.

Famous quotes containing the words alternatives and/or nourishment:
“The last alternatives they face
Of face, without the life to save,
Being from all salvation weaned
A stag charged both at heel and head:
Who would come back is turned a fiend
Instructed by the fiery dead.”
—Allen Tate (1899–1979)
“I was, being human, born alone;
I am, being woman, hard beset;
I live by squeezing from a stone
The little nourishment I get.”
—Elinor Wylie (1885–1928)
