Section 2. RiverSurveyor Instrument Configuration and Options
The RiverSurveyor discharge measurement system is flexible enough to fit most every field set-
up requirement you will need. The core system includes everything you need to make a direct-
connect discharge measurement from a manned powerboat and external power supply. The op-
tions are modular, designed to be used with any S5 or M9 system, to best suit your field meas-
urement needs. The following is a brief description of the core system and the options available
with the new RiverSurveyor discharge measurement system.
2.1. RiverSurveyor Core System S5 and M9
The core system includes:
Multi Frequency ADP (S5 or M9)
Power/Comm Cable (Std. 10m)
The S5 and M9 ADPs integrate a compass/2-axis tilt sensor, temperature sensor, 8-GB internal
recorder, and a vertical acoustic beam (echo-sounder) for depth measurement.
• S5 (Figure 1): This portable, 5-beam ADP with a velocity profiling range of 0.2 to 5.0 m is
ideal for use in shallow channels. The S5 has a 5-inch (13-cm) diameter Delrin housing that
narrows to 3.2 inches (8.1-cm). It has four 3.0-MHz velocity measurement transducers in a
Janus configuration. A 1.0-MHz vertical acoustic beam (echo sounder) provides depth da-
ta.
