The scheme was proposed in early 1958, and began to carry out in 1974. The key component, a 3-ton concave hyperboloidal main mirror, is made of V02 type cervit with its diameter of 2.2 m, clear aperture of 2,16 m and its focal length of 6.48 m.展开更多

Universities of East Anglia and St. Andrews, a 4-day experiment was conducted on a ridge- and -runnel beach of north Norfolk on the North Sea coast- Detailed surveys were made of every low water of an area 10m by 30m and electromagnetic current meters were used to measure wave- induced currents over the ridge and in the runnel- The locations of bedform fields were noted, fluorescent sand was used to follow the sand movement and, at the end of the experiment, lacquer peels were taken of the top 0-2 m of a vertical section through the ridge- and- runnel-During the 4 days 0-75 m3 of sand per metre width of beach accreted in the runnel and a similar volume was eroded from the upper foreshore. The dominant shoreward transport, identified qualitatively by the movement of the fluorescent sand, suggests the ridge- and- runnel system migrated shorewards up the general beach slope of 1 by 2 - 3 m.
