Extending a model we previously used to calculate magnetization hysteresis arising from the geometrical barrier in a flat, bulk-pinning-free type-II superconducting strip subjected to a perpendicular magnetic field H{sub a}, we here calculate the contribution, arising from screening currents on the top and bottom surfaces, to the magnetic-field-dependent critical current I{sub c}(H{sub a}) due to surface barriers, including both the geometrical barrier and the Bean-Livingston barrier. {copyright} {ital 1998} {ital The American Physical Society}
