A fiberglass 0.5-foot H Flume with integral approach section used to measure field runoff as part of a ground cover study.  Over the flume a stainless steel ultrasonic transducer bracket has been mounted  at the point of measurement (where the high visibility staff gauge is located).

Approach sections help to calm and condition flows before they enter H Flumes.  They also serve as a convenient location in which to mount flow conditioners and pipe stubs.
