  • The canals of China·Northern Europe are different from those of Korea in the phases of the times and physical environment as follows. As the coefficient of river regime is high and the slopes of river is high in our country, the sediments are much deposited on the floor and river channels are meandered and the depth of water are low. So we should dredge the river floor and should construct the dams and lock gates. These will cause streams to be late and to be flooded. The rising and falling of groundwater tables may be fatal to the buildings. The ecosystem will be ruined by water pollution and rising of water levels. We are concerned about the economy of the canals, the low velocity of the canals, reduction of the transportation cost, transshipment cost and terminal cost, tourism·leisure-typed waterway and extreme cost of waterway development. It is proper for us to put in good order and control waterway simply by means of annual schedule, not to construct canal.
