Abstract

Experimental investigation of the effect of particle geometry on the values of hydraulic
conductivity using 5 plastic particle fractions of different shapes and sizes is presented in this
paper. Conducted experiments serve as a background for ongoing research focused on sediment
transport of erodible bed in tilting flume. When a flowing mixture of water and particles evolves
above a stationary bed, the determination of flow rate of water filtered through stationary bed is
very important in order to estimate the inaccuracy of total flow rate trough the flume. In order to
evaluate the amount of infiltrate water, experiments were carried out in both laminar and turbulent
flow regimes. The transition area was identified, and the results show only small effect of particle
geometry on the transition between regimes. Experimentally identified values of hydraulic
conductivity were used to calculate the amount of infiltrate water in the tilting flume for different
inclination angles. Experimentally identified values of hydraulic conductivity are, for example,
useful in designing industrial water filters, as the materials used to conduct experiments and those
in filters are similar.
