mean low water

“The high gravel content and the loose soils mean low water retention — important in our humid climate — while the vine roots will be able to dig deep. Variations in the slope — northwest or southwest — will allow them to plant several varieties, to make more interesting wines,” he said.

The National Weather Service in Charleston reports that a tide of 8.8 feet above mean low water early Saturday tied the third-highest on record.

To give you an idea of the size, from mean low water to tip of blade, these would be 550 feet tall.

Under an act of 1907 the channel of Fernandina harbour, 1300 ft. wide at the entrance and about 2 m. long, was dredged to a depth of 20 to 24 ft. at mean low water with a width of 400 to 600 ft.

The design was, accordingly, modified in 1902, by commencing the stepped courses of large stones at 12 ft. below mean low water on each slope, instead of at low water raising this kind of superstructure to 22 ft. above low water in place of 18 ft., and capping the stepped courses at the top by large blocks of stone, 20 ft. long and 5 ft. deep, laid across the breakwater, which thus presented a marked resemblance to the upper section of the mound at Civita Vecchia.
