THEORETICAL APPROACH OF UNIFORM FLOW VELOCITY THROUGH GROIN PILES
Abstract: Research of uniform
flow velocity through groin piles was developed on hydraulic laboratory, which differs
from previous research because model of structure is groin piles. Uniform flow
is influenced by two shear stress namely bottom shear stress and shear stress
due to the piles of groin. Theory of uniform flow velocity is obtained by
equating the shear stress due to waves and shear stress due to permeable
groins. Theoretical approach verified by research in the laboratory using eight
models of piles with density ranging between 18.4% - 31.4%. The verification
results show that the measurement data of uniform flow velocity in the
laboratory close to the results of calculations using the theory.
