Natural Stable Channel Design with Bio-Technical Slope Stabilization

Harris County Flood Control District, White Oak Bayou

Prime Consultant and Engineer of Record for the Design of HCFCD 125-00-00-X07

  • Natural Stable Channel Design (NSCD) with Bio-technical Stabilization for 3,600 ft of channel is being accomplished by performing
    • Geomorphic stream conditions assessments, and the watershed characterization
    • Flow analysis, and detailed study of the terrain where erosion failures are evident
    • Geotech assessments for consolidation, rapid drawdown, and slope stability for the design flows
    • HEC-RAS assessments to evaluate the design alternatives and ensure they do not introduce downstream impacts.
    • Tailored use of bent weirs, bio-logs, live stakes, mac-mat, MacRay-anchors for erosion control
    • Low-Impact-Design using Bio-Stabilization technique and earth reinforcement with geo-grid in the upstream stretch
    • Traditional Riprap design and Gabions for stabilizing the upper banks of the selective Natural Stable Channel sections.
  • Existing ROW and the encroachments are addressed to optimize the channel configuration
  • Section 404 Nationwide Permit was obtained from USACE for channel realignment and rehabilitations.
