We find that rivers with high sediment loads experience annual migration rates that are higher than those of rivers with lower sediment loads.
Because faster meander migration and higher cutoff rates lead to increased sediment-storage space in the resulting oxbows, we suggest that sediment supply modulates the reshaping of floodplain environments by meandering rivers. provided technical expertise in analysing channel change from remote sensing data.'

Results: Scores on m PAQLQ subscales and overall Qo L were not normally distributed, indicating that parametric tests may not be appropriate.
Results of statistically significant differences in overall mean Qo L scores between caregiver and children differed with parametric methods (paired ≤ 0.15).
We conclude that imposed sediment loads influence planform changes in lowland rivers across the Amazon. The study was supported by NERC grant NE/I002081/1, NASA grant NAG5-6120, the Don J.
