抄録

In the rainy monsoon districts of Eastern Asia, irrigation canals sometimes form very characteristic networks, such as in the lower reaches of the Tikugoriver in Japan and along the Yangtse kiang in China.
In this paper the writer discusses the development of these networks and their adaptation to environmental conditions.
A classification of canal types is then given, and brief explanations are added regarding their distribution and their topographical significance.
