Big Sioux Bank Stabilization

Big Sioux Bank Stabilization

Project Description

The team of Inter-Fluve, Infrastructure Design Group, Inc., and AE2S were selected to complete a survey and analysis of the Big Sioux River from approximately Baltic to Sioux Falls.  Several areas along the Big Sioux River have seen significant erosion over the decades causing significant sedimentation in the river.  Previous stabilization attempts within this stretch of the river continue to see high erosion issues and require further analysis.  The combined team selected for this study have extensive background in surveying, river analysis, geomorphic analysis, and bank stabilization design solutions.  

Inter-Fluve’s expertise within the project includes examination of potential bank treatment sites using forensic geomorphology.  Potential solutions which will be evaluated include large wood structure stabilization techniques.Similar to Inter-Fluve, AE2S will provide the team with additional hydraulic modeling capabilities and assessment of applicable locations for hard armoring type treatment.AE2S will also assist in local coordination, permitting, and public involvement.

InfrastructureDG is responsible for overall public involvement and river survey.  Over the length of the project reach, 15 different locations were identified for potential stabilization analysis locations.  To complete the hydraulic analysis accurately, 315 river cross sections will be completed by the InfrastructureDG survey team.  Providing this information will be completed via a series of surveying techniques including, manned watercraft GPS and sonar, boots on the ground data collection, and unmanned sonar equipment.

I’ve had the privilige to work with Infrastructure Design Group on several projects.  They have a great team who go the extra mile to make sure their customer is satisfied.  They deliver their services in a timely and accurate manner and will provide input and advice to make sure the project is planned correctly during the design stage.
