Short summary
The effect of buoyancy and bottom slope on the runout and entrainment capacity of experimentally reproduced saline gravity currents is studied. The shape of the current is modified due to the entrainment of ambient water, particularly within the body region. For steep slopes, two opposite mechanisms of mass exchange are identified: the current entrainment of water from the upper surface due to the enhanced friction at the interface and the head feeding by a rear-fed current.
