Section 1. Getting Started
1.1. What does the System do?
The SonTek RiverSurveyor system is a robust and highly accurate Acoustic Doppler Profiler
(ADP) system specifically designed to measure river discharge, 3-Dimensional water currents,
depths, and bathymetry from a moving or stationary vessel. The RiverSurveyor system com-
bines proven state-of-the-art acoustic Doppler velocity profiler instrumentation with a Windows-
based software package that can be used on a Personal Computer (PC) or Mobile device (using
cell phone technology). The high degree of accuracy and ease of use allows you to measure
confidently without having to change measurement settings for a specific river condition.
First-time users will find data collection and analysis a relatively simple task, while advanced
users will benefit from the flexible processing and analytical tools that are provided. One of the
major benefits of the RiverSurveyor system is that it is easy to program – time-consuming and
complicated training courses are not required before you can start collecting meaningful data.
1.2. What’s new?
Shallow and/or deep water profiling solutions – The ADP can be either one of the following
types. Both of these profilers are described in detail in Section 2.
•
S5 ADP : A five-beam system with four profiling beams and one vertical beam. The S5 has
a velocity measurement range of up to 5 m and a discharge measurement range of 15 m
(when referencing GPS and the vertical beam).
•
M9 ADP : A nine-beam system with two sets of four profiling beams (each set having its
own frequency) and one vertical beam. The M9 has a velocity profiling range of up to 30 m
and a discharge measurement range of 80 m (when referencing GPS and the vertical
beam).
Multi-frequency – Multiple acoustic frequencies fused with precise bandwidth control make for
the most robust and continuous shallow-to-deep measurements ever for an ADP. A determinis-
tic microcontroller automatically apportions the appropriate acoustics and pulse schemes as you
cross the river. This allows you to focus on the measurement technique, and not on the instru-
ment setup. The end result of the automatic adjustments is that it gives you the best measure-
ment settings possible at all times, no matter the depth and velocity of the river.
Automated cell size adjustments – As you go from shallow to deep water, the cell size auto-
matically adjusts to optimize performance and resolution. This feature further enhances your
ability to measure continuously in dynamic river conditions.
Vertical beam – A low-frequency, fast-sampling vertical beam extends the maximum depth
range of the system and provides superior channel definition for river discharge measurements
and bathymetric surveys. The vertical beam also provides you the confidence that you will
measure the proper depth during extreme conditions such as high-sediment flows and floods.
Integrated GPS, Power, and Communications – The RiverSurveyor Power and Communica-
tions Module (PCM) brings unmatched ease of use and flexibility to the S5 and M9 ADPs. The
PCM contains a rechargeable battery pack for power, factory-configured Bluetooth
®
radio or
Spread Spectrum (SS) radio (for communication with a PC or a compatible Mobile device; see
§6.2), and an optional GPS enclosed in a water-tight housing.
RTK GPS integration – Available exclusively from SonTek, the RTK (real-time kinematic) GPS
optional solution is easy to use and offers incredibly precise positioning and fast data sampling
rates (10-Hz). This option can augment or be an alternative to Bottom-Track and positioning.
Unlike existing “Differential” GPS solutions, which sometimes requires 50+ meters width for a
