In many countries around the world, from North America to Aisa and from Europe to Africa, river trasnportation is extremely important and these countries could not survive without river transportation. To some extent, river transportation is dealt with in a similar way to seafreight and pretty much any type of cargo can be transportated along some of the larger rivers in the world. Other rivers may have width and depth problems, requiring the cargos to be transported overland instead. Your freight forwarder should be able to advise you in respect of this mode of transportation.
