Inputs

Enter geometry, lining thickness, and optional costing.
White theme
Exports always include SI values for consistency.
Trapezoid uses side slope (H:V).
Total lined canal length.
Use full lined depth including freeboard if needed.
For trapezoid only. Example: 1.5 means 1.5H:1V.
Optional top-edge strip lining per side.
Common values: 75-150 mm or 3-6 in.
Covers laps, spillage, and field losses.
Typical: 2400 kg/m^3 for normal concrete.
Choose how material and cost are estimated.
Example: $, Rs, EUR, GBP
Estimates steel mass from kg/m^2 rate.
Optional lump sum for mobilization or tools.
Tip: If you switch unit system, the form resets displayed units.

Example data table

Section Length (m) Bottom (m) Depth (m) Slope Z Thickness (mm) Waste (%) Area (m^2) Volume (m^3)
Trapezoidal 250 2.0 1.5 1.5 100 5 ~1,304 ~130.4
Rectangular 120 1.2 1.0 - 80 3 ~384 ~30.7
Trapezoidal 500 3.0 2.0 2.0 125 7 ~3,869 ~483.6
Example outputs are rounded estimates for demonstration.

Formula used

  • Trapezoidal side length: s = d * sqrt(1 + z^2)
  • Wetted perimeter: P = b + 2s (trapezoidal) or P = b + 2d (rectangular)
  • Lining area (net): A = (P * L) + (2 * e * L), where e is edge strip width per side
  • Concrete volume (net): V = A * t
  • Waste adjustment: A_w = A * (1 + w), V_w = V * (1 + w), where w is waste fraction
  • Mesh steel (optional): Steel = (kg/m^2 rate) * A_w
  • Mix estimation (if selected): Dry volume uses factor 1.54 and split by ratio.
