Abstract

The watershed management needs data of hydrology circulation, e.g. volume of water flow and weight of suspension. Rain is a main control for hydrology circulation. Rain characteristics need to be assessed for their effectagainst hydrology circulation. This research was aimed to assess the effect of rain characteristics and to create an equation of volume of water flow and weight of suspension in karst area. A combination method of explorationand statistic calculation was used in this research. Parameters of volume of water flow and weight of suspensionwas measured at several different of water levels. The data were analyzed to assess the rain characteristics that influenced hydrology circulation. The result showed that 30 minutes maximum intensity (I 30’) affected the volume of water flow and weight of suspension. The functions raised from this research were V = 563.646 (I 30’ )–644.063and W = 59.660 (I 30’ )–209.758.
