Yo Flipface!
Welcome to the madness of topo and ground crews. The worst is when you have cross sections that are not in line, so that top of the curved curb overlaps the bottom of the curved curb.
If the bottom of the waterway is uniformly sloped, you can always add a point along a tin line to add the triangles you are seeking. You always want to be careful but in some cases it works well. I will often do this along a paved street when I have some proof that it works - ie if they missed the left gutter but I have a centerline and right gutter that show a typical crown with uniform pitch.
In both these instances there appears to be a significant grade break parallel with the valley or ridge (can't tell which) that wasn't identified before the model was built. Add those grade breaks, and it'll look a lot better. I agree with those who recommend fixing the model first and let the software take care of the contouring.

Same here. Contour is a function of the model.
If you have data gathered at required density and correct breaklines, contours should look decent. I never played with triangles swapping and all that good stuff. Heard about it. Don't like it, that sounds too complicated. I prefer to deal with points and breaklines. Some software are more friendly that way.
I do not smooth either. As was mentioned, it's already an interpolation, so it's, in my opinion, adjusting something that's already adjusted.
For crying out loud, people

Has everyone forgotten how to draft simple lines? It's not brain surgery! If I was silly enough to hire someone who was silly enough to deliver to me a contour map with contour lines crossing and insane kinks, bends and sharp points where none exist in fact, I would be prudent enough to not pay one red cent for that work and would hand-deliver a complaint to the BOR. Just because someone is able to generate a load of crap does not mean they should be compensated for doing so. Anyone unwilling to make the effort to make a contour map resemble what is really out there deserves to be removed from service (licensure). Any licensee supervising and accepting such practice is much more guilty than the ignorant field worker. Trying to put the blame on the software is like trying to blame your car-installed GPS when you drive off a cliff at 70 mph. You must take full responsibility for your own foolish behavior. Then you need to take corrective actions and then set up an internal system to prevent this type of thing from ever happening again.
Contour Line Question " Sinc"
This is worth watching for 20 minutes of your time. It will present a lot of scenarios for you to create and 'polish' (small p ) your drawing.
Richard was such a treasure of knowledge here but he left this surface much too soon.
Of course, there are some of lesser vision who may think that his license should have been yanked.
