Civil Engineering Calculations
This program was designed to provide Civil Engineers and Land Surveyors with a quick way to calculate or check drainage/flow calculations. Great for use in the office, while checking through plans, or in the field when you need some quick effective calculations.
This tool is great for plan checkers, surveyors, and engineers. Great for Civil Engineering Students, and Professionals.
This app is the beginning of a port from my iPhone application also called Civil Engineering Calculations.
Drainage Functions
- Mannings Pipe Flow
- Calculate Discharge
- Calculate Pipe Size
- Calculate Wet Perimeter
- Channel Flow
- Calculate Discharge
- Approximate Free-Board
- Check Rectangular, Trapezoidal, and V-Ditch Sections
Please let me know of any other feature requests. I will continue to update this with any ideas that I receive (Website or App Store comments).


I’ve buyed your application, but i’ve some comments regarding the hydraulics calculation (Pipe & channel):
1) What about the flow Velocity output? If this information is missing, the app has no sense.
2) Please add others calculation criteria such as Gauckler-Stricker, Bazin, Kutter.
Thanks and Regards
