山科川流域の流出特性について ―山科川下流部の内水(1)―

Abstract

The hydrological observations have been carried out from 1963 in Yamashina River basinhaving the area of 56.1 kin2, with an aim to make clear the hydraulic behaviour of inundatedwater in low-lying district.As the first step of the studies, the basin has been divided into some of small-basins suchas mainly characterized by the bush land with steep slope, the thickly wooded hill, the urbanland and the paddy basin, respectively. The runoff characteristics of these basins have beenexamined in the form of equivalent roughness in the method of runoff analysis by character-istics of the uniform flow, and the results are tabulated in Table 1.
