A means of transportation as well as erosion. 7 of 19 Vertical Erosion Erosion which occurs vertically. For example; when a river gouges out a deep valley. 8 of 19 Lateral Erosion Erosion which occurs laterally. For example; at the outside bend of a meander. 9 of 19 Traction The rolling along of large boulders along the river bed. 10 of 19 Saltation The 'bouncing' movement of small stones along the river bed. 11 of 19 Suspension Small material carried within the water. (Sand & Silt) 12 of 19 Long Profile A line representing the course of the river from the source, to its mouth where it enters the sea or a lake. 13 of 19 Cross Profile A line that represents what it would be like to walk from one side of a valley, across a channel and up the other side. 14 of 19 Waterfall The sudden and often vertical drop of a river along its course. 15 of 19 Gorge A narrow, steep sided valley. 16 of 19 Meander A bend or curve in the river channel. 17 of 19 Hard Engineering Building artificial structures aimed at controlling natural processes. 18 of 19 Soft Engineering Tries to work with the natural river system and avoids building on areas liable to flooding. 19 of 19
