Grant-in-Aid for Scientific Research 【 display / non-display 】

  • Numerical investigation on stability of gravel bags in flooding as flexible riverbank protection works and a new design method

    Grant-in-Aid for Scientific Research(C)

    Project Year: 2019.04  -  2022.03 

    Direct: 3,400,000 (YEN)  Overheads: 4,420,000 (YEN)  Total: 1,020,000 (YEN)

  • Effects of sizes and shapes of particles on water and particle motions and bed structures in gravel-bed rivers

    Grant-in-Aid for Research Activity start-up

    Project Year: 2013.08  -  2015.03 

    Investigator(s): FUKUDA TOMOO 

    Direct: 2,100,000 (YEN)  Overheads: 2,730,000 (YEN)  Total: 630,000 (YEN)

    　View Summary

    We conducted numerical mixed-size gravel movable-bed experiments using a numerical movable-bed channel capable of simulating motions of flow and gravel. To investigate effects of particle sizes on their motions, contact forces of moving particles exerted in collision with movable bed were measured for each particle size in the experiment. The result showed that relatively large particles received more upward contact forces than those of small particles. We also conducted numerical movable-bed experiments with spheres. Effects of particle shapes on gravel motions were investigated by the comparison between gravel and sphere motions. The result showed that a difference of fractional sediment transport rates of gravel was smaller than that of spheres.

  • Investigation of dynamic mechanisms near river beds employing a numerical mixed-size movable-bed channel with arbitrary shaped particles

    Grant-in-Aid for challenging Exploratory Research

    Project Year: 2013.04  -  2015.03 

    Investigator(s): FUKUOKA SHOJI, UCHIDA Tatsuhiko, FUKUDA Tomoo 

    Direct: 3,100,000 (YEN)  Overheads: 4,030,000 (YEN)  Total: 930,000 (YEN)

    　View Summary

    We developed a numerical movable-bed channel capable of simulating three-dimensional motions of flows and gravel particles in different shapes. Flow and gravel motions and forces exerting them that have been difficult to measure were predicted by numerical movable-bed experiments. The result of the experiments showed that large particles were nearly in rectilinear motions in upper positions on the bed surface and small particles took detours in the lower positions. It was also showed that relatively large particles affected greatly by their shapes in motion and settlement.
