The velocity of propagation of a variety of gravity motivated density currents is given. Several stratification configurations of the ambient fluid environment are considered. Applications are given to surface warm discharge in lakes or reservoirs, the spreading of a slug of sewage sludge at the thermocline level of the sea or lake, and the spreading of oil slick on water surface. Extension of the result to axisymmetric spreading is also given.
