Determination of sample points to take physical condition data on the location of the research is done by using purposive sampling, that the determination of sample points with a certain considerations. The result of the calculation of average river flow in the dry season 3 m3 / sec and average discharge in the rainy season is 68.7 m3 / sec. While the amount of sediment loads (QS) in the dry season is at 24.97651 tons / year and the amount (QS) during the rainy season is 769.1134 tons / year.
