Validation experiments of Ultrasound Image Velocimetry (UIV) applied in cohesive sediments (fluid mud)
<p>A standard ultrasound imaging transducer was towed trough mud at known velocities. During this movement ultrasound images were acquired at high frequency (+/- 350 Hz). Based on these images the relative velocity between the transducer and the mud was deduced using the OpenPIV script (Python version). The output was compared to the imposed velocity of the transducer to validate the accurcy of the UIV technique applied in mud. This was done for various velocities ranging from 500 mm/s to 1750 mm/s in increments of 250 mm/s. The density of the mud was fixed at 1.15 g/cm³ and the ultrasound frequency to 3.5 MHz. The combination of PIV algorithm applied to ultrasound images is referred to as Ultrasound Image Velocimetry (UIV).</p>

Modeling Flocculation Processes of Cohesive Sediment Through Moment Methodology
<p>The data were used in the paper "Modeling Flocculation Processes of Cohesive Sediment Through Moment Methodology" which was submitted to "<em>Water Resources Research</em>". In this paper, a new mechanistic Lagrangian-type flocculation dynamic model was proposed by solving the population balance equation with moment methodology and similarity transformation, and the influence of particles' surface heterogeneities (<em>F</em><sub>2a</sub>) was incorporated. Furthermore, the roles of shear rate, sediment concentration, particle size and surface heterogeneity were investigated theoretically.</p>
PIE LTER trapping capacity of suspended cohesive sediments of subdomains at Plum Island Sound, Massachusetts (numerical simulations).
Trapping capacity of suspended cohesive sediments of subdomains at Plum Island Sound, Massachusetts (from numerical simulations) are predicted using 2D Delft3D FLOW/MOR model and vegetation module during different stages of tidal height and direction.
