Abstract

The study on the characteristics of precipitation stream surface discharge and physiographic factors in influencing flood vulnerability at Cimanuk Watershed West Java is essential since Cimanuk Delta is one of the most growing river delta in West Java. Furthermore regression based model between flood as dependant variable has been regarded as the most suitable approach. Highest rate of monthly daily average daily precipitations and high stream discharge were focused in November to April. Therefore higher probability of flood occurence in Cimanuk watershed may concentrated only in those months. Correlation between highest rate of stream discharges occurence frequency and the occurence frequency of highest rate of monthly daily average and daily precipitations were 0.807 0.96 0.162 respectively. The highest rate of stream discharge can be determined by measuring the highest rate of monthly daily average and daily precipitations. However it should be kept in mind that the highest rate of daily precipitation hold insignificant correlation with stream discharge. In all months of the year the factors have positive effect on flood vulnerability are precipitation soil type and land cover but the slope has negative effect.
