主题：【原创】世界上最窄的跨海运河希腊柯林斯运河 -- 潮起潮落

以前看到过它的照片，但不知道是在何地。

查了一下维基。此运河深8米，长6346米。顶部宽度为24.6米，底部宽度为21.3米。两侧悬崖高度为90米，坡度为80度。跨越运河有一条铁路和两条公路。

该运河于1893年竣工。可以节约航程700公里。但由于太狭窄，不适于现代货轮通过。目前其航运价值不高，主要用于旅游者游览。每年通过11000艘船只。

这里绝对是玩蹦极的好地方。

The canal consists of a single channel 8 metres (26 ft) deep, excavated at sea level (thus requiring no locks), measuring 6,346 metres (20,820 ft) long by 24.6 metres (81 ft) wide at the top and 21.3 metres (70 ft) wide at the bottom. The rock walls, which rise 90 metres (300 ft) above sea level, are at a near-vertical 80° angle.[29][30] The canal is crossed by a railway line, a road and a motorway at a height of about 45 metres (148 ft). In 1988 submersible bridges were installed at sea level at each end of the canal, by the eastern harbour of Isthmia and the western harbour of Poseidonia.[31]

Although the canal saves the 700-kilometre (430 mi) journey around the Peloponnese, it is too narrow for modern ocean freighters, as it can only accommodate ships of a width of up to 16.5 metres (54 ft) and a draught of 7.3 metres (24 ft). Ships can only pass through the canal one at a time on a one-way system. Larger ships have to be towed by tugs.[31] The canal is nowadays mostly used by tourist ships; 11,000 ships per year travel through the waterway
