The instability of the head shape of gravity current is investigated through CFD and EFD. The instability plays an important role in mixing stage. Three-dimensional instability of the head of gravity current is investigated by the experiments of the lock-exchange flow and by the computation using four different types of water tank. The flow visualization experiments are carried out with LIF technique to observe the three-dimension features of the head advancing along an channel. The numerical results show a good agreement with the experiments on the shape of gravity-current.
