IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Impact of acoustic doppler technology on catchment hydrology
Author : DANIEL WAGENAAR(1), ISAAC JONES(2)
ABSTRACT
The application of Acoustic Doppler instruments has grown significantly over the past decade from where it was
originally introduced to hydrographic operations for the measurement of runoff in natural catchments to flood
management in urban catchments such as the SMART tunnel project where it is accepted today as the primary method
for instantaneous and continuous velocity measurements by most organizations.
The scope of Acoustic Doppler instruments have expanded form the initial requirement of velocity measurements to the
collection of parameters for determining the total suspended sediment load, bathymetric mapping and the development
of hydrological and hydraulic models. The application of Acoustic Doppler Velocity Meters in sediment research to date
has demonstrated the capability of the SonTek SL Series in the continuous monitoring of both suspended sediment
concentration and water velocity.
Bathymetric surveys have become an increasing requirement for most catchment hydrology studies especially with the
ability to combine data sets with Lidar or other digital elevation data products. SonTek has developed a bathymetric
survey package (HydroSurveyor) that is based on the well-established RiverSurveyor platform. The combination of a
bathymetric survey package with an Acoustic Doppler Current Profiler has enabled the collection of associated datasets
with the standard bathymetry survey information such as horizontal and vertical velocity profiles. The ability to perform
bathymetric surveys in combination with water velocity measurements makes the HydroSurveyor an attractive and costeffective
solution for model development such as prediction of oil or chemical spills on coastal environment.
The expansion of the Acoustic Doppler instrumentation applications within the different facets of catchment hydrology is
showcased in this presentation and highlights the versatility of the technology and the capability of SonTek Acoustic
Doppler instruments in flood management, sediment transport and bathymetric surveys for model development.
