The relation of flood-frequency characteristics and mean annual runoff values to active-channel and depositional-bar geometry are presented for six regions in the Missouri River basin. Equations were derived by regression analyses based on the correlation of flow characteristics with the dimensions of the channel geometry. The flow characteristics also were related to the drainage area and a precipitation parameter for comparison. Data for continuous-record gaging stations were used in the derivation. The standard errors for the equations relating either active-channel or depositional-bar widths to mean annual runoff ranged from 26 to 53 percent. The equations relating either active-channel or depositional-bar widths to the flood-frequency discharges of 2, 5, 10, 25, 50, and 100 years had standard errors ranging from 29 to 84 percent.
