Tools Used

• Pipe Sizing Calculator
  Supporting

  Discharge from velocity × area.

• Documented Water-Flow Continuity Record
  Reference

  Station equipment budget.

Reference Materials

• Stable Reach

  Install gauges on straight, uniform channels — bends distort stage-discharge relationships.

• Flood Season

  Mark escape routes and secure equipment before high-flow season.

• Swift Water

  Never wade above knee depth in moving water without a tether and spotter.
