HydroCulv 1.2
http://forum.civilea.com/Thread-hydroculv-1-2
The required input data consists of culvert geometry and flow boundary condition data. Predefined shapes include round, ellipse, arch, and box. The user may also define an irregular shape by inputing culvert widths at various depths. Profiles can be calculated for up to five sets of boundary conditions in each run. Tailwater head elevation can be input directly, or calculated by HydroCulv based on downstream channel parameters. The validity and completeness of the data is checked prior to program execution.

The culvert hydraulics model is capable of modelling all possible flow profiles at a culvert, including full flow, inlet control, and combinations of gradually varied flow for subcritical and supercritical flow, including hydraulic jumps. Normal depth and critical depth are calculated and used to aid in selecting the applicable profile. Any time supercritical flow is identified, a momentum balance is performed to check for and locate hydraulic jumps, and inlet control is checked for.

Output options include tables of key results and profile data, and plots of the profiles and rating curves. The profile plots show the water surface elevation profile superimposed on an outline of the culvert. A description of the flow profile is included, enabling the user to quickly understand what is happening throughout the culvert. The rating curve plots show the sensitivity of the key results to discharge. All output can be either copied to the Clipboard for transfer to other programs, or directed to the printer.

An old software free for use.

I would like to warn the users of this program, and to ask them to check their results carefully. The reason for my worries is some "instability" in the algorithm it uses to calculate GVF in the pipe.

My advise is for the users to try to make a rating curve using different discharges (or opposite - different depths for constant discharge). And later this rating curve should be observed for outliers for some discharges. The "dangerous" curve looks in such way, that for single or a range of discharges the U/S depths are rising with tenths of meters, and for discharges above this "wrong range" the depths are going back to their expected values. Sometimes this range is quite narrow. Without examining the rating curve you can't be sure that your result didn't fall in the "wrong range".

Just to explain - these outliers are not related to hydraulic jump, occurring in the pipe.
