Here the answers if you did not manage to copy on Thursday!
January 18, 2008: What does A Hjulstrom graph show us?
1. Sand can be picked up/eroded at lower velocities than either finer or coarser particles – e.g. sand vs clay
2. Because clay particles are cohesive they need a velocity similar to that of pebbles to be picked up/dislodged
3. The velocity required to maintain particles in suspension is less than the velocity needed to pick them up – for clays it is virtually nil!
4. For coarser particles the boundary between transportation and deposition is narrow – only a small drop in velocity leads to sedimentation/ deposition
