Flow Rate and Velocity Calculation

Dronelab offers accurate and efficient flow rate and velocity calculations in watercourses.

Our experienced professionals perform detailed hydraulic measurements in rivers and open channels using traditional methods, including:

  • Width and depth measurement techniques:
    • Application of topographic methods such as levelings, cross-sections, and other techniques to accurately determine the watercourse cross-sectional area.
    • Processing of the collected data using specialized software.
  • Current meters:
    • Deployment of mechanical or acoustic current meters to accurately measure the water flow velocity at various points in the watercourse.
    • Processing of the measured data to obtain the average flow velocity in the watercourse.

Flow rate calculation:

  • Determination of the average flow velocity by combining data from current meters and hydraulic models.
  • Calculation of the water cross-sectional area based on width and depth measurement data.
  • Flow rate calculation by multiplying the average flow velocity by the water cross-sectional area.

Report preparation:

  • Detailed report with measurement results, calculations, and conclusions.
  • Recommendations for further watercourse management and hydraulic engineering design.

Advantages of traditional methods:

  • Affordability: These methods are widely used and do not require the purchase of expensive drone technology.
  • Experience: Dronelab specialists have extensive experience in applying traditional methods, providing accurate and reliable results.
  • Flexibility: Traditional methods can be adapted to various watercourse conditions and hydraulic measurement tasks.


  • Hydraulic engineering design: Flow rate and velocity data are crucial for designing bridges, dams, culverts, and other hydraulic structures.
  • River management: Flow velocity data can help identify erosion risks, sediment deposition, and other hydrodynamic processes affecting the riverbed.
  • Environmental monitoring: Flow rate data can be used to assess water quality, pollution spread, and ecosystem health.
  • Research: Traditional methods are still widely used in studying hydrodynamic processes and watercourse modeling.
