SUMMARY

  • 1
     The equipment and methods needed for collecting the data required for near-bed flow regime classification are detailed.
  • 2
     To illustrate appropriate procedures for data analysis, data collected from four cobble bed streams are used to classify near-bed flow regimes both at the measured depth and at estimated bankfull depth.
  • 3
     Implications of the resulting classifications are discussed from a limnological perspective. It is concluded that while the biological relevance of near-bed flow regimes has not been formally established, the terms ‘pool’, ‘run’, and ‘riffle’ are not always useful for differentiating between habitats in the near-bed zone.
