Abstract: We present hydro-morphologic laboratory experiments on propagation of aggrading sediment fronts. The simultaneous measurements of feeding discharge, water elevation and flume bed elevation are performed by shooting movies with multiple action cameras and following image analysis. River sediment transport has numerous implications for, among others, channel and structure stability, ecology, and flood hazard. We performed an experimental study to observe the hydro-morphologic response of a flume subject to bed-load sediment transport and non-equilibrium sediment feeding. Here we focus on the experimental method used to measure the key quantities, that involved both the experimental controls and the flume response. Literature studies of the topic employed different techniques. The distinctive feature of the present work is that all the key measurements are performed using suitable image processing methods.
