渇水の地域的特性とその要因構造分析

Abstract

In this paper, firstly we choose the percent-day of water supply control as an index of severity ofdrought and find out the relationship among the percent-day index and climatic, hydrological, socio-economical factors and the degree of progress of water resources development, based on multipleregression analysis. Secondly we collect the occurrence and non-occurrence urban areas of droughtand do search the reason why the drought occurs in one area and does not occur in another area, based on discriminant analysis. Lastly we apply those analyses to the drought at 1978.
