Gravel‐bed braided rivers are characterized by shallow, branching flow across low relief,
complex, and mobile bed topography. These conditions present a major challenge for the …

For centuries, scientists have been attempting to map complex hydraulic processes to
empirical formulas using different flow resistance definitions, which are further applied in …

The simulation of sediment transport by three-dimensional (3D) modelling is linked with the
question of how accurate such models are. The current paper provides a test where detailed …

A methodology is presented to quantify the mean flow field in a natural river with a boat‐
mounted acoustic Doppler current profiler (ADCP). Moving‐vessel (MV) and fixed‐vessel …

Bank vegetation plays a key role in both hydrodynamics and morphodynamics of natural
rivers; however, these effects are often unaccounted for in the computational flow dynamics …

We present large-eddy simulations (LES) of riverine flow in a study reach in the Sacramento
River, California. The riverbed bathymetry was surveyed in high-resolution using a …

Methodologies are presented to (1) evaluate the effect of acoustic Doppler current profiler
(ADCP) motion on velocity measurements,(2) assess the stationarity of velocity time series …

Four algorithms are described for computing a steady free water surface with the solution of
the three-dimensional (3D) Navier–Stokes equations. The numerical methods are used in …

The SSII program was developed in 1990-91 during the work with my dr. ing. degree at the
Division of Hydraulic Engineering at the Norwegian Institute of Technology. SSII is an …
