Bedform diagram showing the \(10^{\,\circ } \hbox {C}\)-equivalent mean bed sediment size against \(10^{\,\circ } \hbox {C}\)-equivalent mean flow velocity for \(10^{\,\circ } \hbox {C}\)-equivalent flow depths between 0.25 and 0.4 m after Southard and Boguchwal (1990). Indication of the equivalent temperature is needed due to the effect of temperature on fluid viscosity and density. The diagram shows that current ripples are likely to occur at mean flow velocities between roughly 0.1 and 0.9 m/s and at a sediment size of roughly 0.1–0.8 mm
