Description: Opens with footage of the first Nant-Y-Gro demolition trial on a full size dam, preceded by shots of the contact charge being put in place from a rowing boat.

At Building Research Station Garston (Watford), several items then show model dams equipped with fairly primitive monitoring equipment being subjected to explosive charges.
