The utility model relates to a device for measuring the muddy water permeability coefficient of a porous cover plate for a side slope drainage ditch, which comprises a sewage supply and convergence device, a porous cover plate placing device and a water seepage amount centralized measurement device, the water seepage amount centralized measurement device comprises a drainage channel, a triangular weir installed in the drainage channel and a triangular weir measuring needle. A to-be-measured porous cover plate is placed in the porous cover plate placing device, then rainfall is simulated through the sewage supply and convergence device, and simulated sewage falls onto the porous cover plate in a raining form. And the sewage passing through the porous cover plate flows into the drainage channel, so that the permeability coefficient eta of the porous cover plate is measured. And finally, fitting the relationship between different rainfall intensities and the permeability coefficient eta to obtain the permeabilit
