Key to Methods - Stream Features

 

Length: the length of all stream segments within the watershed.

Stream Order: The reported stream order was determined from the Strahler stream ordering system (Strahler, 1952).

Stream Reach Type: The reach classification system (Parham and Lapp, 2006) was developed by Bishop Museum researchers in collaboration with DAR biologists to provide a general classification of stream reaches that could be applied systematically to all streams on all islands. The reach types are based on elevation and the presence of different sized barriers (waterfalls) in the stream.

  • Estuary: all stream segments between the coast line and 1 m. elevation.
  • Lower Reach: stream segments between 1 and 20 m. elevation and below any barrier of approximately 10 m. high.
  • Middle Reach: stream segments greater then 20 m elevation or above the first 10 m barrier and less than 200 m. elevation or below the first 20 m high barrier.
  • Upper Reach: stream segments greater then 200 m elevation or above the first 20 m barrier and less than 750 m. elevation.
  • Headwaters: stream segments greater then 750 m. elevation.
