Abstract
A new method is introduced by using high precision accelerometer and gyroscope
micro-electromechanical sensors (MEMS), which can record Lagrangian observations of
sediments and shed light into the dynamics of sediment transport processes at above threshold
conditions. The sensor can be used under a range of well-controlled flow conditions and can
record measurements at high frequency (200 Hz), which can be used at the field. The smart sphere
performance was evaluated by comparing its rotation and acceleration readings from the sensors
to the video recordings of both top and underwater high-speed camera for a range of flow rates
and sphere densities. Furthermore, an initial attempt to compare the smart-sphere’s velocity is
achieved, by transforming the particle’s velocity from the Lagrangian frame of reference, obtained
from the inertial sensor, to its velocity at the Eularian frame, obtained from the top camera.
