The behaviour of inclined slurry pipelines at shutdown was studied using different active lengths of pipe. The ultimate settled condition was found to depend on pipe slope in the same fashion as for much shorter pipes. Pressure changes observed at the bottom of the slope gave a good indication of the time scale of the settling/flow process. A preliminary interpretation of the process is provided by a model in which inertial forces, compressibility effects and axial variations of velocities are neglected.
