Abstract This study experimentally documented the thresholds of critical motion for tropical shallow marine carbonate sediments by conducting a total 225 laboratory experiments that included analysis nine median sediment diameters and five water depths. A shape factor, Sf , which quantifies single particle, was evaluated during investigation. Both Shields parameter incipient mean velocity were used to represent motion. The coral reef then compared with results from quartz sand. experimental...
This study utilized 50 laboratory experiments to document the evolution of coral beaches under varying regular wave conditions, including five distinct periods and ten heights. Both type equilibrium beach shape sand bars were used represent evolution. The was then compared quartz beaches. experimental results show that predicted (modeled) profile a not applicable Compared on beaches, distance from bar crests berm in greater, whereas erosional depth troughs deeper. However, grain size...
Abstract The motion of particle clouds (i.e., sediment clouds) usually can be found in engineering applications such as wastewater discharge, land reclamation, and marine bed capping. In this paper, a series laboratory tests are conducted on coral sand to investigate the shape feature single mixing processes clouds. is measured quantified. experimental results demonstrate that particles tends spherical size decreases, empirical equations were established explain variation D 50 f S,50 sand....
Understanding the motion thresholds of shells is important, as shell allows analysis beach profiles, prevents excessive erosion coastline, and helps to resource use discarded shells, providing new ideas for protection beaches. In this study, orientational motions two types typical molluscan bivalve gastropod were investigated by means flume experiments. The final orientations with statistically highest number occurrences during each used initial respective threshold flow velocity...
Understanding settling motion of coral grains is important in terms protection reef systems and resotoration the associated ecosystems. In this paper, a series laboratory experiments was conducted to investigate motion, using optical microscopy measure shape parameters particle-filtering-based object tracking reconstruct three-dimensional trajectory. Three characteristic descent regimes, namely, tumbling, chaotic fluttering, are classified based on trajectory, spiral radius variation...
