This paper systematically presents the current situation and prospects of basic and applied research of electrohydraulic effect. From the angle of basic research, the initial mechanism, development process, and shock wave formation of liquid discharge are introduced, respectively. The key points and difficulties of future research, such as the transient process of important parameters in the process of discharge initiation and development, are put forward in the aspects of modelling and experimental methods. From the angle of applied research, the current technology situation and application status in two scenarios: ocean and land of sparker source, which is the most widely applied technology of liquid discharge, are introduced in detail. Meanwhile, the development trend of deep water sparker source and controllable output of shock wave are discussed briefly in the application fields such as deep ocean resource investigation and underwater acoustic research.
