Investigation on the depositional characteristics of suspended particles in porous media is crucial to prevent groundwater artificial recharge blockage. In this study, first, particle image velocimetry (PIV) technology was used to extract a 2D porous media skeleton structure formed by spherical superabsorbent resin particles. Second, based on the temperature influence analysis on the physical–chemical properties (including fluid viscosity, relative dielectric constant and zeta potential of solid surface), the Lattice Boltzmann Method‐Immersed Moving Boundary‐Discrete Element Method (LBM‐IBM‐DEM) coupling model was used to simulate suspended particle motion in porous media. The relationships between the suspended particle motion states, stable deposition forms, suspended particle spatial distribution and the collaborative influence of pressure difference, particle size and temperature are innovatively revealed. The results are as follows: (1) In the ‘first temperature effect range’, the suspended particles change in two states of detachment after adsorption and stable deposition. In the ‘second temperature effect range’, the suspended particles change in two states of stable deposition and migration. (2) The non‐uniformity of suspended particle spatial distribution in porous medium increases with the increasing of particle size and the decreasing of pressure difference. However, the temperature effect on suspended particle spatial distribution is weak. (3) Influence weights of pressure difference, particle size and temperature on the suspended particle motion are 2.92, 1.04 and 0.8, respectively.
