River Engineering and Stream Restoration

River engineering and stream restoration expertise for the hydraulic design of bridges, culverts, dikes, diversions, and hydraulic structures.

Schlumberger Water Services (SWS) provides river engineering and stream restoration expertise for the hydraulic design of bridges, culverts, dikes, diversions, and hydraulic structures. Schlumberger Water Services is a leader in the application of hydrodynamic models for river engineering and flood hazard mapping. We use highly complex modeling and analysis programs to verify the engineering needs of various types of projects. Services that are required to manage river engineering work include

  • two-dimensional modeling
  • unsteady-state flow simulation
  • water surface profile analysis
  • wind setup modeling
  • dam breach analysis

Projects that demonstrate our dam rehabilitation services include the following.

St. Vincent Highway hydrodynamic modeling study
Location
- Minnesota, USA
Client - Minnesota Department of Transportation
Description - SWS carried out a hydrodynamic modeling study of the effects of raising the St. Vincent Highway. The work included setup of the MIKE 11 hydrodynamic model, simulation of alternative highway grades, and assessment of impacts on upstream and downstream water levels. SWS also designed waterway openings including bridges and culverts for mitigation of flood levels. The results were presented at a public meeting in St. Vincent, Minnesota.


Fraser River sediment transport modeling
Location
- British Columbia, Canada
Client - City of Chilliwack and British Columbia Ministry of Environment, Lands and Parks
Description - SWS developed a MIKE 11 hydrodynamic sediment transport model of the Fraser River near the confluence of the Fraser River and Harrison River to simulate morphological changes including bed scour and gravel aggradation. Alternative configurations for stream restoration were investigated to determine whether the river would scour a deeper and wider channel and thus reduce design flood levels in the vicinity of the city of Chilliwack. The scope of work included GIS mapping of the confluence area, a geomorphological assessment of bank erosion over time, and an environmental assessment.


Flood hazard mapping for the Skeena River at Terrace
Location
- British Columbia, Canada, Client City of Terrace
Description - The City of Terrace retained SWS to prepare flood hazard mapping for floodplain areas within the city. The scope of work included setting up a MIKE 11 hydrodynamic model and determining depths of flooding, erosion rates, and potential avulsion paths. A hazard evaluation rating for floodplain zones and a color-coded flood hazard map were prepared. Appropriate development guidelines for each hazard area were recommended.
