This work presents a short review on the advances of plasma beam dump modelling since they have been first proposed. Analytical models have been derived to estimate the beam energy loss for both passive and active beam dump schemes. For the passive case in particular, tailored plasma density profiles can improve beam-energy extraction by mitigating particle re-acceleration. A semi-analytical model, consisting of the dynamics of test-particles experiencing the previously derived analytical wakefields, is under development to investigate deceleration beyond the saturation point, in the linear to the quasi-linear regime.
