Progo River is one of the rivers that has a sediment supply from volcanic and non-volcanic areas. Sediment transport, especially bedload transport, is very influential on the phenomenon of degradation and aggradation. Therefore, a study is needed to determine the characteristics of bedload transport. The research was carried out in the downstream of Progo River. Sampling locations were in four locations, namely Ancol Bridge, Kebon Agung II, Kebon Agung I Bridge and Bantar Bridge. The bedload transport measurement tool uses Helley Smith equipment. Based on the result, the type of sediment in bedload transport is sandy silt, with a value of density of 2.67 to 2.70. The average diameter value (D50) of bedload transport varies, from 0.10 mm to 0.558 mm. The value of bedload transport varies and is influenced by the value of the discharge. The correlation between bedload transport and discharge is linear.
