Long profile - the gradient of the river bed from the source to the mouth - shows you how the gradient changes over the different courses, Shape of river profile from source to mouth - concave, Type of erosion in upper course - hydraulic, attrition and abrasion, Main type of erosion in middle course - Some attrition but mainly abrasion, Type of erosion in lower course - lateral erosion due to abrasion, Type of river transport in upper course - traction mainly - large boulder move, Type of transport in middle course - some saltation, mostly suspension, The main type of river transport in lower course - mainly solution and suspension, Deposition in upper course - large bouders, Deposition in middle course - inside the slower moving water of a meander bend, Deposition in the lower course - Dominant process with lots of fine sediment depositied, Reasons for increase in water volume as you move down the profile - more water from tributaries, Transverse profile - Bank to bank view across a river channel, Upper course channel shape - Shallow and narrow V shape, Shape of channel in middle course - Deeper and widens , Change in shape of lower course - Less gradient so lateral erosion and meandering, Landforms in the upper course - Valleys, Gorges, waterfalls, Features of the middle course of a river - Lower gradient, starts to meander, widens. Maybe a waterfall, Base level - The lowest level to which a river can erode, Alluvium - Deposits of clay, sand, and gravel left by rivers and streams after flooding,
