  abstract = {{A}coustic {D}oppler devices ({U}nidata {S}tarflow) have been deployed for velocity measurements and discharge estimates in five contrasted open-channel flow environments, with particular attention given to the influence of sediment transport on instrument performance. {T}he analysis is based on both field observations and flume experiments. {T}hese confirm the ability of the {S}tarflow to provide reliable discharge time-series, but point out its limitations when sediment is being transported. (i) {A}fter calibration of the instrument by the {I}ndex {V}elocity {M}ethod, the deviation from reference discharge measurements was <20% at the 95% confidence level. (ii) {I}n ungauged conditions at high flows, the {S}tarflow was particularly useful in providing velocity data for approximating measurements of discharge. (iii) {H}owever, channel and flume experiments revealed the effects of mobilised sediment on velocity estimates: coarse particles (>= 150 mu m) transported by way of saltation or as bedload caused a significant underestimation of velocity by as much as 50%; a slight underestimation (10-15%) was also observed when significant quantities of fine particles (<= 150 mu m) were transported in suspension; this underestimation was shown to reach 20-30% when suspended sediment concentrations were very high (c. 50-100 g {L}-1).},
