A classification of river basins and hydrological regionalization
(as exemplified by Japan)

An array of issues relating to the establishment of homogeneous hydrological areas is considered. A set of methods of analysis is suggested with a view to achieve the maximum possible objective resolution of these problems. The regionalization methodology has been tested through the creation of a classification of river basins and a regionalization of the territory of the Islands of Japan from formation conditions of extreme floods by using a broad gamut of morphometric and structural-hydrographic characteristics of catchments. It is found that the selected areas and their boundaries bear striking similarities to the spatial location of geological structures and are closely coincident with the main tectonic fields and their boundaries.
