In weakly pinning type-II superconductors the vortex lattice can flow coherently under the action of a Lorentz force. This type of collective vortex motion in a random potential is manifested by channeling of the vortex flow along preferred paths which are stable in time. We present direct experimental observations of such vortex flow {open_quotes}channels{close_quotes} obtained with magnetic decoration experiments on NbSe{sub 2} single crystals. {copyright} {ital 1997} {ital The American Physical Society}
