Geomorphology
Management and restoration of natural systems begins with a fundamental understanding of watershed-wide and local geomorphic factors which influence:
  • Sources of sediment to streams
  • Sediment transport rates
  • Channel Stability
  • Landscape response to episodic disturbances
  • Hydraulic geometry of channels
  • Peak flows
  • Low flows
Balance geologists and geomorphologists have direct experience in these areas resulting from hundreds of hours of direct collection of field data, geomorphic mapping, and quantitative evaluations throughout California, Oregon, and Alaska.
