Which of the following is used to measure streamflow?
A)Reservoirs
B)Barometer and sling psychrometer
C)Statistical methods of probability
D)Stilling well and staff gauge

Question

Quizplus · Accepted Answer

Stilling wells and staff gauges are commonly used to measure streamflow. Stilling wells are structures that regulate the water level, allowing for more accurate readings of stream flow. Staff gauges consist of a scale on a vertical pole, which is placed partially or completely submerged in the stream. By measuring the height of the water against the gauge, the streamflow can be determined. Reservoirs are not used for measuring streamflow, but they may be used for water supply storage. Barometers and sling psychrometers are used for measuring atmospheric pressure and humidity, respectively, and are not directly related to measuring streamflow. Statistical methods of probability may be used to analyze streamflow data, but are not used for direct measurement of streamflow.
