Sediment Transport Erosion Control
Taylor Engineering conducts sediment transport studies to identify and resolve problems that occur when sediments reduce or could impair the effectiveness of bridges, reservoirs, channels, and floodways. Depending on the complexity of the flow regime, these studies typically require the application of one-dimensional, two-dimensional, or three-dimensional numerical models, which simulate the transport and fate of sediments in various water bodies. The list below indicates sediment transport models familiar to the company’s engineers.
One-dimensional models — appropriate for shallow and narrow rivers, streams, and channels exhibiting flow in one principal horizontal direction and velocity magnitude or velocity variations perpendicular to the principal flow direction.
- MIKE 11 – Simulates non-cohesive sediment transport and morphological conditions
- HEC-6 – Simulates sediment transport to predict changes in river profiles resulting from scour or deposition
- HEC-RAS – The most recent version simulates sediment transport and movable boundary calculations resulting from scour and deposition over moderate time periods
Two-dimensional models — appropriate for shallow and wide waterways such as bays, estuaries, lakes, and coastal areas exhibiting flow along two principal horizontal directions with small flow velocities along the water column.
- MIKE 21 – Simulates vertically averaged cohesive and non-cohesive sediment transport to determine patterns in erosion and deposition including changes in bed elevations.
- SED-2D – Simulates vertically averaged cohesive and non-cohesive sediment transport in open flow channels
Three-dimensional models — appropriate for deep and wide waterways exhibiting significant changes in flow velocity along the depth, for wide and shallow or narrow and deep waterways where water properties such as temperature and salinity greatly varies with depth (layered flow).
- MIKE3 – Simulates cohesive and non-cohesive sediment transport in lakes, estuaries, coastal waters, and seas
