Based on the pulsed current interception of underwater discharge, the characteristics of the steepness of electrohydraulic shock waves (EHSWs) and the peak value still increasing slowly with the electrical energy injection after the acceleration expansion phase of the plasma channel are investigated. The one-dimensional “piston” model of the EHSW generation is improved, and the calculation method for the EHSWs based on the “piston” model is modified. The modified model takes the change of starting points and the rising steepness of EHSWs into account, and the rising edge and peak value of EHSWs can be calculated more precisely.
