Numerical model simulations of channel flow for the South Saskatchewan River, Canada
The dataset consists of two files, one with simulation results for a river bed characterised by alluvial bedforms (dunes) and one for a smooth river bed without dunes.
This work was part of NERC project NE/L00738X/1. Digital Surface Models (DSMs) were constructed using imagery obtained on four occasions (13th May 2015; 2nd Sept 2016; 8th June 2017; and 12th June 2017).

Provenance & quality
Modelling was carried out using the open source CFD package OpenFOAM to solve the three-dimensional Navier-Stokes equations with a Re-Normalization Group (RNG) k-epsilon turbulence closure. The free surface was represented in the model with a rigid-lid approximation. Inlet conditions were defined using measured flow velocities. A Neumann pressure condition was set at the outlet. Second order central differencing numerical schemes were used for gradients, second order bounded central differencing for divergence; and an unbounded second order deferred corrected scheme for the Laplacian surface normal gradients were employed. Convergence criteria were iteratively tested and set to a tolerance of 1x10-8 for pressure and 1x10-10 for velocity, k and epsilon. Solver tolerances were set to 1x10-10 for pressure and 1x10-12 for velocity. The results of two simulations are included here.
