Abstract：The study of the transportation and deposition characteristics of suspended particles in porous media is of great significance to engineering problems such as oil exploration，groundwater recharge and pollutant transportation. The advances in this area are presented in this paper with particular reference to mathematical models and experimental studies. A new transportation and deposition model was proposed based on data from field monitoring and a large number of laboratory tests. The transportation and deposition characteristics of suspended particles were studied under different conditions. The new mathematical model taking into account the velocity correction parameter，the porosity correction parameter，the particle capture efficiency and the variation of porosity was then established. Deficiencies of current experimental studies and mathematical models include the failure to accurately describe the pore structure of porous media，the neglecting of multi-factor coupling effects on the transportation and deposition characteristics，and the failure to properly integrate the macro-scale filtration phenomenon and the meso-scale particle motion. Future studies are expected to follow these four major directions：(1) Development of a dynamic three-dimensional experimental facility；(2) Establishment of a more accurate spatial model for porous media；(3) Development of mathematical models for particle transportation and deposition under the coupling effects of multiple factors；(4) Development of the theory and analytical methods for particle transportation and deposition across micro-meso-macro scales.
