Water Barrier Predictions for Riverine Vessel Defense

Predictions of the amount of water thrown upward from shallow depth explosions are presented in support of a new water barrier concept for the protection of Riverine vessels. The predictions are obtained using a model based on a generalized formulation of hydrodynamics using an incompressible liquid assumption, which has been previously validated on a variety of applications including water plume predictions. Depending on both the charge weight and initial depth, this study presents estimates for the Effective Water Length (EWL) values at heights and time intervals relevant for riverine vessel protection from Rocket Propelled Grenade (RPG) attacks.
