(D)GPS - Differential Global Positioning System
Recording of cross-section coordinates in rivers
The (D)GPS upgrade is possible for Rio Grande with Riverboat, for RiverRay and Q-Boat 1800. In case of a moving bed it is recommendable to use (D)GPS instead of the Section-by-Section module. Furthermore the (D)GPS equipment is mandatory for recording of crosssection coordinates, e.g. for hydraulic modelling. The accuracy is highly depending on the quality of satellite reception and the correction signal.

Cable Chimp
Remote-controlled system for crossing rivers
The cable chimp allows a slow and constant crossing of the ADCP systems and therefore ensures an accurate collection of velocity and discharge data. The system is remote-controlled from the river bank. The cable trolley can be used with the three ADCP systems RiverRay, Rio Grande and StreamPro. A discharge measurement at sites with bad access is thus easier. The cable chimp can also be used with existing cable way installations.

The Q-Boat 1800 allows a safe and uncrewed measurement in case of floods. The two outboard engines and the V-shaped hull ensure an easy control even in turbulent waters.
WinRiver II Software
Registration and analysis of discharge measurements
The software WinRiver II is used to record and analyse velocity and discharge measurements of mobile ADCP systems.
The configuration of the measurement system can be done by running the "Measurement Wizard". Site-specific settings and different modes can be chosen to adapt the measurement device to different river conditions.
After finishing the measurement, the playback menu offers the possibility to correct the measurement settings and to reanalyse the measurement. For the analysis itself, several tables and graphics are available.
The software WinRiver II can also used for the operation with StreamPro in combination with a long-range SEBA bluetooth module.
StreamPro Software
Registration and analysis of discharge measurements with StreamPro
In combination with the SEBA bluetooth module,Software StreamPro can be used to record and compare measurements with StreamPro on your HDA (Hydrological Digital Assistent).
With the SEBA HDA as an easy-to-handle, lightweight and waterproof device, your mobile discharge measurement is sure to be an innovative experience. Our self-explanatory software StreamPro alleviates the measurement with your StreamPro. Tabulation allows a comparison and analysis of discharge measurements directly at site.
After finishing a measurement with software StreamPro, your data can be imported in WinRiver II easily and comfortably. Afterwards, the measurement can be managed and processed professionally as usual.
Section-by-Section Software
Registration and analysis of discharge measurements in verticals
The software Section-by-Section is used to record and analyse discharge measurements of mobile ADCP systems in verticals.
With Section-by-Section software, water velocity and depth data is actually acquired at a series of fixed locations across the measured body of water.With Section-by-Section, the specific verticals were analysed and the total discharge is determined. Because Section-by-Section is similar to conventional measurement methods, it’s extremely easy to learn.
