Coastal transport infrastructure in the Mediterranean
With regards to the coastal zone the development of maritime
transport is inherently linked to the development of coastal infrastructures such as ports and motorways and railways connecting inland areas to the ports. The development of large logistic coastal infrastructures brings, amongst others, fragmentation of coastal landscapes and habitats, changes in the land use and increased pollution loads

Zambezi River Basin navigation system
Navigation on the Zambezi River is both international and local. The main international transport routes are the Kazungula and
Luangwa-Kanyemba, while major national routes are in the upper Zambezi River and on Lake Malawi/Niassa/Nyasa. There are also

The water cycle
Environment water transport system.
The water cycle consists of precipitation, vapour transport, evaporation, evapo-transpiration, infiltration, groundwater flow and runoff. Figure 1 explains the global water cycle, illustrating how nearly 577,000 km3 of water circulates through the cycle each year. A table of estimated residence times shows the approximate times that water resources exist as biospheric water, atmospheric water and so on.
