B)Barometer and sling psychrometer.
C)Statistical methods of probability.
D)Reservoirs.

Question

Quizplus · Accepted Answer

Stilling wells and staff gauges are commonly used to measure streamflow. A stilling well is a structure installed in the stream that creates calm water next to the gauge, allowing for more accurate measurement. A staff gauge is mounted vertically next to the stream, with water level measured relative to the gauge. Together, these tools provide a reliable way to measure streamflow. Barometers and sling psychrometers are used to measure atmospheric pressure and humidity, respectively, and are not relevant to streamflow. Statistical methods of probability can be used to analyze streamflow data, but not to directly measure it. Reservoirs are artificial bodies of water created for various purposes, including water supply and flood control, but they are not used to measure streamflow.
