Bedload Monitoring by means of Hydro - Acoustic Techniques
Conevski, Slaven (Doctoral theses at NTNU;2020:47, Doctoral thesis, 2020)The bedload distribution through the alluvial streams contributes in shaping of the river morphology. Therefore, bedload transport data are fundamental requirement for proper management of engineering practices in complex ... -
Bedload Velocity and Backscattering Strength from Mobile Sediment Bed: A Laboratory Investigation Comparing Bistatic Versus Monostatic Acoustic Configuration
Conevski, Slaven; Alexio, Rui; Guerrero, Massimo; Ruther, Nils (Peer reviewed; Journal article, 2020)Despite the many advantages of using active ultrasound sonars, recent studies have shown that the specific acoustic geometry, signal-processing configuration, and complex surface-volume scattering process at the riverbed ... -
Development of a method for suspended sediment transport monitoring by means of ADCP measurements
Aleixio, Rui; Guerrero, Massimo; Ruther, Nils; Stokseth, Siri (Journal article; Peer reviewed, 2018)Monitoring stations in rivers and water courses are an important mean to obtain critical data about the different variables that play a role in the hydrodynamics and ecological processes. Measuring suspended sediment ... -
Evaluation of an acoustic Doppler technique for bed-load transport measurements in sand-bed Rivers
Conevski, Slaven; Winterscheid, Axel; Ruther, Nils; Guerrero, Massimo; Rennie, Colin (Journal article; Peer reviewed, 2018)The bottom tracking (BT) feature of the acoustic Doppler current profilers (ADCP) have emerged as a promising technique in evaluating the bed load. Strong statistical correlations are reported between the ADCP BT velocity ... -
New Techniques for Estimating Sediment Load for the Catchment of Banja HPP
Sørås, Sigurd (Master thesis, 2017)toring water in artificial reservoirs is a common method for ensuring constant water supply for among others irrigation, electricity and drinking water. The construction of such artificial storages will disturb the natural ... -
The acoustic properties of suspended sediment in large rivers: Consequences on ADCP methods applicability
Guerrero, Massimo; Ruther, Nils; Szupiany, Ricardo; Haun, Stefan; Baranya, Sandor; Latosinski, Francisco (Journal article; Peer reviewed, 2016)The use of echo-levels from Acoustic Doppler Current Profiler (ADCP) recordings has become more and more common for estimating suspended bed-material and wash loads in rivers over the last decade. Empirical, semi-empirical ... -
Towards an establishment of a rating curve for suspended sediment transport by means of ADCP measurements
Ruther, Nils; Aleixio, Rui; Guerrero, Massimo; Sørås, Sigurd; Stokseth, Siri (Journal article; Peer reviewed, 2018)This study presents a series of acoustic current Doppler profiler (ADCP) measurements, which are converted into suspended load concentrations (SSC). Depending on the particle size distribution (PSD), the sound backscatter ...
