This is the most flexible and thorough hydraulic analysis app you will find in the App Store, with 48 different calculations for 14 structure types.

No other app gives you as much flexibility when it comes to selecting which variables to solve for, completing every calculation with ease, efficiency, and most importantly, accuracy.  Using Flo Hydraulic Calculator you can calculate:

Circular Pipe - Solve for flow, normal depth, diameter, and slope.
Rectangular Channel - Solve for flow, normal depth, height, width, and slope.
Trapezoidal Channel - Solve for flow, normal depth, width, and slope.
Gutter (Uniform and Composite) - Solve for flow, cross slope, road slope, and spread.
Weir (Rectangular, V-Notch, Cipolletti, and Generic) - Solve for flow, length, angle, and head.
Orifice (Rectangular, Circular, and Generic) - Solve for flow, height, diameter, area, and head.
Elliptical Pipe - Solve for flow, depth, and slope.
V Shaped Channel - Solve for flow, depth, and slope.

Nationally recognized method’s of design are used for all calculations such as the Federal Highway Administration’s Hydraulic Engineering Circular No. 22 (HEC-22), and the United States Bureau of Reclamation Water Measurement Manual.

•Unique User Interface, custom number pad for faster input
•Optimized for the iPhone 4 retina display

    I'm a consulting engineer and use this app frequently at the office and in the field. Handy and helpful.

  • Great app

    by Hydro engineer

    This is a must have for the tool box!

  • Great tool for civil engineers

    by ThomRR

    I use this app to get quick answers at work. Almost always provides an answer that stands up to more formal and rigorous analysis.

  • Civil Engineer

    by CynAnneRCE

    Very easy to use, well worth the $ spent.

  • Good app

    by Lacivilgirl

    App works great. One thing I would like to see - velocity calculated using Manning's Equation. It's a very handy tool to have in any Engineer's arsenal.

  • A Must Have

    by mikedeezenuteez

    Unbelievably easy to use, calcs gutter flow, weir flow, pipe, channels, etc. Well worth the $10.00

  • So surprised

    by bettafishbubbles

    the best hydraulic calculator on the app store, hands down. i have tried others and they are pitiful compared to this. this is like Flowmaster on the go and is so useful! this is a must have for any civil engineer. the animation feature the developer added is so cool, that I find myself playing around on the app! love it!!

  • Like Flowmaster in your pocket!

    by 1Louder

    Great update! The pipe animation is a nice touch. Reporting feature will definitely come in handy!

  • Excellent App!

    by ProE2011

    Great tool for open channel flow analysis. Very useful results. Easy to use. Very helpul info pages!

  • Made for civil engineers by a civil engineer

    by SiriusBlack7

    The ultimate tool for anyone in land development or H&H. Only app that can compute gutter flow on the app store.

  • Well Engineered

    by Hello0806

    Great App! Great interface and keyboard! Does all calculations I need. Thanks!

  • Awesome app!

    by artxtra7

    The best civil engineering app I've come across. It does all types of hydraulic calculations with ease. The unit conversion feature is slick, fast and easy!!!

  • Amazing

    by Meems135

    Incredibly useful! I recommend it.
