    abstract = {Algeria is located in the category of countries poor in water resources, fast silting up passing the 65 millions of m3 year <SUP>1</SUP>. It reduced considerably storage capacity of many reservoirs. In order to remedy several inconveniences of dredging used mainly in Algeria, we propose a method that is like the Water Injection Dredging (WID). It consists in injecting water resulting in an overtaking of material resistance, from where it appears a failure area. Underflow provoked by opening of outlet gate acts like a flushing. It was possible to us to value volume recovered of restraint with a simplified theoretical formulation of injection and modelling of behaviour hydromechanics of injected soil massifs and resolution equations gotten by finite element. Survey is completed by a scale model study. One could provide interesting indications on efficiency of method proposed while showing existence of critical values for pressure and speed of injection; values open to several technological interpretations.}
