Solid particle detachment, transport and deposition in natural or artificial porous media have been the subject of an intense research effort in the last four decades. Particle-facilitated contaminants transport, accidents due to internal erosion in the hydraulic structures and permeability decreases of the oil wells, drinking water supply or artificial recharge of the aquifers, aroused a growing interest. In this study, results of two laboratory experimental systems for tracer tests in columns are presented. System 1 concerns step-input injection method where two studies were realized. The first study is devoted for studying deposition kinetics (K-dep) of the Suspended Particles (SP) and the second for evaluation the porous medium damage (clogging and release). However, system 2 concerns the pulse injection method whose aim was to study the SP deposition kinetics. The interpretation and analysis of the Break-Through Curves (BTCs) were obtained using the analytical and numerical solution of convection-dispersion equation (1D) including a source term (deposition and release term). Using system 2 results showed a decrease of the deposition kinetics coefficient with flow velocity until a critical velocity where K-dep decreases. For high injected volumes of the SP in system 1, the permeability decreases occurs throughout of the entrance of the porous medium.
