Approach
Vessels with a draft of more than 14 metres should use the IJgeul.
To protect access to the channel jetties were built in the sea.
In 1957 the Delft Hydraulics Laboratory began research for the best solution. The result was two jettties with 500 m difference in length between the southern and the northern one. The length of the north pier should be 1500 m to 2500 m and the south jetty of about 3000 m. This is to prevent the silting of the entrance channel and to ensure that vessels entering suffer less from the prevailing south-west and north-south flow along the coast.

Famous quotes containing the word approach:
“A lady with whom I was riding in the forest said to me that the woods always seemed to her to wait, as if the genii who inhabit them suspend their deeds until the wayfarer had passed onward; a thought which poetry has celebrated in the dance of the fairies, which breaks off on the approach of human feet.”
—Ralph Waldo Emerson (1803–1882)
“I maintain that Truth is a pathless land, and you cannot approach it by any path whatsoever, by any religion, by any sect.”
—Jiddu Krishnamurti (1895–1986)
“The white man regards the universe as a gigantic machine hurtling through time and space to its final destruction: individuals in it are but tiny organisms with private lives that lead to private deaths: personal power, success and fame are the absolute measures of values, the things to live for. This outlook on life divides the universe into a host of individual little entities which cannot help being in constant conflict thereby hastening the approach of the hour of their final destruction.”
—Policy statement, 1944, of the Youth League of the African National Congress. pt. 2, ch. 4, Fatima Meer, Higher than Hope (1988)
