A set of data on the grain-size of suspended sediments and river basin characteristics has been collected from the first order tributaries of the Middle Yellow River. A systematic study on quantitative relationships between grain-size of suspended sediments and the characteristics of these basins have been made for those river basins by using statistical methods. The following conclusions can be drawn: Precipitation, surface material, drainage density, vegetation coverage and hyperconcentrated flows act as an important controlling factor on the grain-size of suspended sediments in the Middle Yellow River. The grain-size of suspended sediments increases with an increase in drainage density, the maximum suspended sediment concentration and unevenness of precipitation, and decreases with an increase in the percentage of loess and vegetation coverage. Multiple regression analysis has shown that surface material is the most important factor influencing the grain-size of suspended sediments, followed by vegetation, hyperconcentration and precipitation. The drainage density exerts minor influence on the grain-size of suspended sediments.
