—The experiments of injection gravity currents were completed in a rectangular basin by release the fresh water over a salty water surface at rest. The surface flow of lighter liquids horizontally can be considered as a special case of a two dimensional gravity current, and the spreading law of the fresh water is validated by using image processing technique to record the progress of the injection current. The jet fluid was colored and the digital video can have a variation of light intensity in order to obtain the shape of the outer boundary of the gravity current and its distance from the source point with relation to time, initial, or flow parameters of the jet source.
