1. A Staff Gauge is a measuring tool, similar to a tape measure, used to provide a visual indication of the depth of water (typically in a river, flume, or weir). Staff gauges are inexpensive, static, permament, and don't require power and can be an excellent way to measure flow rates or water depths when the situation doesn't call for a full flow meter installation.
Standard Openchannelflow staff gauges are marked in centimeters on one side and feet / tenths / hundredths of a foot on the other. Custom gauges are also available, usually graduated in flow on one side and level on the other.
2. Crest gauge is a device made of solely of a metal pipe, a wooden pole, and crushed cork that is invaluable to providing a one-time measurement of the maximum height (stage) that a stream hits during a high-water event
