If it is on rivers that are in highlands (up in the mountains and are usually narrow) it is gravity, so it erodes downwards. However, if it is in lowlands (in a valley or a flood plain, for example) it is usually the sheer force of water - in other words, the hydraulic action of water + sediments carried by water. Wind can also contribute to water erosion, as it causes waves and it accelerates the water speed.
