This programme deals with the movement of sand along the East Anglian coast and offers some explanations of coastal features like the sand banks off Yarmouth and the many nesses along the coast.

Footage description: | Shots of a house on the cliffs at Overstrand, Norfolk. Shots of a map of East Anglia and aerial shots of the Overstrand area. Andy Fleet introduces the programme. Shots of the lighthouse at Winterton and of Nick McCave standing on an area of sand deposition in front of the old cliffs. He points out that this area has been moving, as a feature, in the same direction as the net sand transport over the past two centuries. An animated map of the area illustrates this point. McCave, standing on the beach, explains how sand is moved down the coast towards Winterton Ness and from there past Yarmouth to Lowestoft. Aerial shots of the Yarmouth area. McCave, with the aid of animated diagrams, put forward two alternative hypotheses which may explain the tidal transport of sand down the East Anglian coast. McCave speculates, briefly, on the reasons for sand bank build up in the Lowestoft/Yarmouth area. Shots of the Lowestoft coast and of a map of the area. Chris Vincent, with the aid of diagrams, explains wave refraction and the resultant energy patterns in the Lowestoft/Yarmouth area as worked out using computer programs. Vincent explains how this results in a sink for the sand in this area. Nick McCave sums up. McCave goes on to describe some of the data gathering techniques on which calculation, such as those above are based. Shots of a buoy and then a current meter being launched from boats. Shots of data from the current meter being collected. McCave, with the aid of maps, animated diagrams and aerial views of the Wash, follows the movement of sediments from the Overstrand area to the Wash. He gives some explanation as to the ripple structure of the sand banks there. With a map of East Anglia and its coast in the background, Andy Fleet sums up the programme. |
