Clips are not offered for this film: a public-domain mark that nothing bears out (no year, or a year no US term has left).

Not offered: its uploader or archive marks it public domain, and nothing the site holds bears that out (its record gives no year, or a year from 1978 on, which no US term has left), so where it is free is not known. Unclear is not offered. Open it at the Europeana.

About

By means of a drainage sluice at Zeeburg, canal water from Amsterdam is discharged into the IJsselmeer and fresh water is taken in from there. For the exchange of water flows there are nine long metal tubes on the bottom of the Merwede Canal, called syphons, which are no longer in use. However, now that the Merwede Canal will be widened and deepened to accommodate increasing shipping traffic, the syphons may become an obstruction and will be removed. SHOTS: - a tugboat brings a floating sheerlegs to the lock; - in the lock, a diver goes into the water to attach mooring lines to the tubes underwater, assisted by workers on a flat deck barge; - the floating sheerlegs slowly hoists the tubes up and places them on the shore.

Human-made No record of this work says a model made it. What this means.
