Abstract
Results of testing the performance of one-dimensional computer model ISIS
Sediment for simulating the behaviour of graded sediments are presented. The
Ackers and White total transport function derived for uniform sediments and the
Parker bedload formula based on graded sediment data were used for sediment
transport computations. The model was tested on the detailed non-equilibrium
graded sediment transport data collected in an 18 m long and 0.8-1.1 m wide
trapezoidal concrete laboratory channel. The test simulations demonstrate that
the use of the Ackers and White transport function does not provide an adequate
prediction of graded se
