The hydraulics of a single layer flow with entrainment is examined with a reduced-gravity model. Expressions are derived for the local change of Froude number and layer thickness as a function of the entrainment velocity. It is shown that entrainment, like friction, acts to force the flow toward criticality, although the layer thickness can increase if the Froude number is smaller than 1/2. For certain Froude numbers the effects of friction and entrainment on the layer thickness and the hydraulic state of the flow are found to be of comparable magnitude.
