I-69 ORX US 41 to US 60 Canoe Creek Hydrology & Hydraulics

  • Hydrology Model revised to include project basin delineations in greater

detail

  • Hydraulic Model extended upstream to cover project area
  • Field survey to pick up the existing roadway, culverts/bridges and

channel sections at Kimsey Lane, US 41, CSX Railroad and North Fork Canoe Creek within the project limits.

  • LiDAR Digital Elevation Model (DEM) Project specific

and contour mapping obtained from point cloud data tiles for the Commonwealth of Kentucky.

  • Modeling Parameters updated
  • Time of Concentration/ Flow lengths
  • Basin areas
  • Runoff Curve Numbers

  • Updated survey implemented at US 41 show the existing bridge and

highway no longer overtop

  • Existing Q50 and Q100 WSELs are shown to be reduced from the

Effective model

Current Revisions

Regional Channel & Basin REV PROPOSED

  • Update: Modifying basin size
  • Results: Attenuation of approximately 600 cfs during the Q100 peak WSEL

decrease of approximately 1.5-ft

  • Moving Forward: City of Henderson can modify the basin to further mitigate their

flooding issues

Additional Inclusions PROPOSED

  • Proposed 3-10’x6’ box culverts at
  • I-69 just south of US 60 and
  • US 60 just west of proposed I-69.
  • Kimsey Lane Option
  • Proposed upstream and downstream channel improvements for the 3-

10’x6’ box culverts to improve tailwater conditions and to avoid adverse impact to the railroad.

  • Proposed bridges for proposed I-69 and its ramps are to be at least the

same size as the existing 3-30 ft span bridge across US 41.
