What is Invertboot?

What is InvertbootThe InvertBoot Can Help the surveying Field Technician in finding and calculating a few of the following known site conditions.

  • Invert

The flowline at the inside lowest point of a culvert cross-section.

  • Allowable headwater depth (AHD)

The allowable depth of water immediately upstream of a culvert, measured from the invert at the first full cross-section of the culvert. Design criteria.

  • Allowable headwater elevation (AHE)

The maximum permissible depth of water surface immediately upstream of the culvert at the design discharge, measured from a datum. Note: datum may differ between software applications; measured from culvert invert or another datum.

  • Headwater elevation

The water surface elevation upstream from a culvert entrance invert, measured from a datum. Note: datum may differ between software applications; measured from culvert invert or another datum.

  • Tailwater depth      

The depth of water immediately downstream from a culvert, measured from the culvert outlet invert.

  • Water depth

Measurement from culvert invert, pool, or channel bottom to the water surface.

In the Field, an existing drainage or the need for ditch relief on a road segment. usually dictates culvert location. The allowable headwater depth (AWD) is the maximum depth of ponded water upstream of the culvert inlet measured vertically from the invert and controls hydraulic design. AWD may be determined by the depth of fill over the culvert, which is dictated by local topography, roadway geometry, and standards. Frequently, a headwater (HW) to culvert diameter (D) ratio is specified, such as HW/D = 1, which places the allowable headwater elevation at the inlet crown of the culvert.
The choice of pipe material, shape, and size may be fixed by economics, availability, site conditions (fill, bedrock, bedload), and fish passage concerns (Gribben 1997).
Site parameters important in the design of culverts include the length and slope of the culvert alignment, allowable headwater, fill depth, and effects on inlet geometry. Fill depth is determined by design loads, local topography, roadway geometry, and standards.

Learn More About Invertboot

The InvertBoot has been created to be easily fitted on the foot of the most
popular Grade Rods such as the Crain SVR 25-Foot Fiberglass Grade Rod.

With the InvertBoot the Surveying or pipe laying technician can find the invert
on as-built Infrastructure, Drainage & sanitary surveying projects as wells as
new development land surveying projects.

InvertBoot is a professional grade tool that will stand up to daily commercial use.
If your project demands accurate, high-quality land surveying equipment that can
help find the invert, InvertBoot is the tool to use. InvertBoot is commercial grade
surveying equipment that is much needed in the industry.
