Generally when you're doing Tc calcs you have to make some initial assumptions about the flow characterics for the gutter or pipe flow segments. Since you don't have a Q yet (that's why you need the Tc!) you can't nail down the cross sectional area of flow in the gutter which you need to get...

hardcor80, I would agree that a slope of at least 1/4" per foot would give proper drainage, however my guess is that your pipes will be fine even if it freezes. Unless the pipe is standing full of water, there will be space above the water for it to expand as it freezes so the pipes shouldn't...

I'd second a lot of what has already been said by others... I started out in government work too but became jaded by the politics. Moved to a small LD firm and it was great for the varied experience. I figured out that I liked LD project management but had to go to a bigger LD firm to find...

Thanks everyone for the replies. You've brought up some good points that have made me consider my style of mentoring. There is a delicate balance between letting someone figure things out on their own (which takes more time and means loss of billable hours) and providing more direct...

I have recently been assigned to mentor two EIT's fresh out of college and was wondering if anyone had any tips for mentoring young engineers. We do civil site and land development, so I would be especially interested to hear from those within the same discipline. Any stories (good or bad)...

Thanks for your information answer Peter, Let me take this a bit further then...Since the Upland Method already includes a sheet flow component, then if it were used to determine the shallow concentrated flow component for the TR-55 method and then combined with the sheet flow component, it...

I've been comparing the figures in TR-55 Fig. 3.1 and NEH-4 Fig. 15.2 (also in HEC 19 Fig. 52) for determining shallow concentrated flow. It looks like the TR-55 figure uses the same data as the NEH-4/HEC 19 figures but the TR-55 doesn't include all the ground cover conditions that NEH-4/HEC 19...

Even if there are no legal repercussions to ignoring a non-compete, I wonder if there may be some practical reasons to honor the contract? The engineering community is a very small one and word gets around. I know in my neck of the woods that many employers would have second thoughts about...

It seems like most people on this thread are in agreement that it's no big deal to ignore a non-compete that has been signed. Maybe this post belongs in the "Ethics" forum, but does anyone see any ethical problems with breaking a contract that was signed? Maybe it can't be enforced by the...

I once had a coworker leave the company and come back in two weeks. It was actually a big moral boost since the remaining employees were overloaded with work and we really liked the guy. The returning employee brought back all these horror stories about the other company and made us all happy...

Background: I work for a small civil firm (11 employees) and for the past 2-3 years we've had an overload of work for our size. So the engineers have been asked to work more hours to compensate. The owner has consistently tried to hire new engineers with little luck. All the while we keep...

I have not been able to verify with FEMA. I did send in the application and am awaiting a response. In doing some other research I noticed that the CFR Section 701.5 "Office of Surface Mining Reclamation and Enforcement, Department of the Interior" defines an intermittent stream as one that...

Just to follow up... I was told by FEMA's consultant (Michael Baker Assoc.) that anything with a drainage area less than 1 square mile did not belong in a FEMA flood zone. So I was told to submit an MT-2 form with a site map that delineates the drainage area showing it to be less than a square...

I have a similar situation as the above-referenced thread (a FEMA Zone A floodplain shows up on a stormwater swale through a farmer's field with a relatively small upstream drainage area). We want to develop the property and simply pipe the flow through it. Does anyone know why FEMA would...
