流出解析에서의 有效雨量分離에 關한 硏究

다국어 초록 (Multilingual Abstract)

In the runoff analysis, it has been recognized that a precise estimation of effective
rainÍall leads to a more accurate runoff analysis.
Up until now, many methods for estimating effective rainfall have been prüposed,
however, none of them were evaluated as being adequate. A method utilizing the relation
between cumulative rainfall and cumulative water losses is generally used as the most
rational method.
However, even this method has a crucial drawback in that the relation between
cumulative rainfall and cumulative water losses is not always identified as a singlevalued
function because of the influences caused by the soil moisture condition in the
catchment, differences in rainfall patterns and so on.
1n this paper, the function , La=(Smax-qb/K). (1-e-p) is proposed, in which
cumulative water losses (Ld) is related by cumu1ative rainfall (p) and discharge at the
beginning of the storm (qb) , to deal with the above problem (Smax ,K ancl α are the
constants inherent in the catchmets).
Applying this method tothe hydrological clata of the Geum River basin , Korea
(Area=7, 179m') and the Kamigamo experimental catchment in Kyoto, Japan (4.39 ha),
the adaptability of this method is higher than that of the previous method which is in
ordinary use (Figs. 11 , 12, 13 and 14).
That is to say, the deviation of data is diminished and the relative ;)error decreases
from 16% to 7% in the Geum River hasin and from 23% to 16% in the Kamigamo
experimental catchment (Tables 3 and 4),
