ADCP - Discharge and velocity measurement in stream - EIVA Categories: HyQuest Solutions America, River/Stream & Canal Discharge Measurement, Water Resources. StreamPro is a 2 MHz Acoustic Doppler Current Profiler (ADCP) 1 designed for medium and small streams with depths up to 6 m. The instrument has gained popularity in practical situations, as the majority of discharge measurements made by the USGS are in streams with mean depths of less than 1 m (Fulford, 1992).The instrument can be operated using two deployment methods: moving . Difference should be less than 2 deg C. Give the ADCP sufficient time to equilibrate to water temperature. the acoustic doppler current profiler (adcp) has evolved during the last 25 years from an experimental instrument capable of measuring velocity and computing discharge in deep water (greater than 11 feet (ft)) to an instrument that is commonly used to measure water velocity and discharge in streams as shallow as 1.0 ft deep (christensen and Although there have been several laboratory studies and some field experiments, quantitative information on the performance of ADCP's under field conditions is relatively rare but essential to proper assessment of the Results indicated that the RiverRay ADCP was easy to use and its . This paper presents a method using Monte Carlo simulations for assessing uncertainty of moving-boat acoustic Doppler current profiler (ADCP) discharge measurements using a software tool known as QUant, which was developed for this purpose. These transects successfully concluded all planned ADCP measurements (i.e. Office Preparation 8. Movement of the bed will cause the boat velocity based on bottom tracking (BT) to be interpreted as an apparent upstream velocity, the calculated downstream water velocity will be reduced, and the corresponding discharge measured in these conditions will be biased low Procedures For Conducting ADCP Discharge Measurements (Caltech and University of Texas) collected depth profiles, sediment profiles, as well as water samples and ADCP transects (i.e. Though somewhat more limited in capability, rod-mounted Acoustic Doppler Velocimeters allow similar functions to be performed while wading through shallow streams.

As ADCP technology has been refined, it has begun to gain acceptance as a viable method for obtaining velocity and discharge data. ADCPs calculate current speed and direction based on the measurement of the Doppler Effect. ADCP data provide near-instantaneous estimates of river discharge across the sampled channels. A minimum of four transects should be made in reciprocal pairs and the four transect discharges averaged to obtain the measured discharge for normal flow conditions. The difference in discharges is a concern, but does Performing this maneuver takes practice. The specifications of this device indicate that it has sufficient resolution and precision to calculate river discharge measurements in water as shallow as 4 ft. With the help of a moving boat, ADCP is moved across the river to sketch the river cross-section. One standard method to measure discharge makes use of ADCPs (Acoustic Doppler Current Profilers). Twenty-six of the 31 measurements differed by less than 5 percent . The instruments used for comparison of measurements of water discharge in rivers were an acoustic Doppler current profiler (ADCP RiverSurveyor S5) manufactured by SonTek and an electromagnetic open channel flow meter (model 801) manufactured by Valeport. This dataset provides river discharge measurements collected at selected locations across the Atchafalaya and Terrebonne Basins in Southern Louisiana, USA, within the Mississippi River Delta (MRD) floodplain. Data Handling and Storage 5. A negative bias in discharge measurements made with an acoustic Doppler current profiler (ADCP) can be caused by the movement of sediment on or near the streambed.
