In this paper, the hydrology of Sun Jia Catchment, a small catchment with mixed agriculture in Subtropical Southeast, China, is studied. The objective of the research is to characterize the catchment flows in an agricultural catchment with an irrigation system in Subtropical China and to estimate catchment irrigation flow using hydrograph analysis methods. In the research, the weighting model and multiple regression model were established to estimate catchment irrigation outflow according to hydrographs of the inflows and outflows of the catchment. In the end, it is concluded that the estimated irrigation outflows amounted to 3 695 mm, 2 613 mm and 2 757 mm during 2001, 2002 and 2003, respectively, which covered 70％, 60％ and 64％ of the total catchment outflows in the corresponding years.
