Situation:
I'm doing a CLOMR based on an effective model given to me by the local county floodplain manager, who is an experienced PE contract guy from a big firm. He says it's the effective model. FEMA says they don't believe it's the effective model and want me to spend the months and/or...
I, in my naiveite, had thought that my days trying to do flood studies off of old, nearly illegible HEC-2 printouts without any digital backup data were long gone. Unfortunately, this appears not to be the case, and I seek advice and assistance.
If you're as old as me you've seen things like...
I did a hydrology study for a land development project a few years back. I was subbed to another engineering firm. Highly urbanized watershed, very flashy floods, which drains down into a ritzy part of town. Apparently an attorney who owns a home downstream of the project just got flooded out...
I have a project with multiple storms defined within it (named "1" "2" "5" etc)
I create a new link.
I select "Link Type (enter hydrograph manually)"
The "Manual" tab appears
Under the "event" dropdown I select "1"
I enter a flow at 0.0 hours (I only want constant flows for each event)
I click...
The site is an industrial scale meal loadout facility. They transfer soy beans and soy bean meal to trucks to be distributed to chicken and hog farms. The transfer hoppers are in a metal shed building on a concrete slab with basically no slope, and the pavement into and out of the building has...
I've run into a situation repeatedly in the past several years, and I need advice.
I do annual inspections for detention ponds and underground stormwater vaults as part of my services. I often run into one that needs heavy maintenance, such as getting a vac truck out or doing a lot of landscape...
A lot of talk on this topic in the podcast circles, vis a vis the Weinsteins, Jordan Peterson, etc. I ran across this gem today:

Has anyone here seen this sort of nonsense leak into the workplace yet, or is...
I've been operating off of a $1 million professional liability (errors/omissions) policy for a very long time now and typically had no problems. Of late, one of my better clients is requesting $2 million on E&O. I'm not sure why, but they're a larger client so it's difficult for me to speak with...
Just curious. With everything going on in Texas hydrology, it'd be nice to not have to go off of TP-40.

State officials saying there is a "natural spring" in the middle of the Oroville earthen dam, that the peizometers in the dam are broken, and that apparently there's nothing at all wrong with either of those two...
Not doing a design, just working out preliminary concept pricing for a client. Presume the client is anticipating hurricane loads in a coastal V zone. Granular sandy soils.

Client is asking me to do some preliminary investigation into building a marina in the Bahamas. Would probably need major dredging, not just of the slip area but also to form sand bars for breakwaters. Also some buildings on piles. They're hurricane sensitive, so they're looking at going for...
I see there's a test and a fee. I also see several courses listed by FEMA. Are the courses required? Is there a professional experience requirement? Is this the sort of thing that only government people can get, or can private engineers go for it as well?

I understand it might vary by state, but what's the general answer?

Block coefficient is defined as the volume of the ship displacement at present draft, divided by the volume of a rectangular block encapsulating the vessel at that same draft.

I don't see any interpolated sections in the model. Tried it with the most current version and also with an older copy of 4.10. Same symptoms.
Any ideas?

A colleague called me up recently with a strange question. He has an industrial site on the ICW, and has to put together a SWPPP for it that includes an estimate of how fast an oil spill will travel down the intercoastal waterway, so he needs an estimate of flow velocity within the ICW itself...
A colleague called me up recently with a strange question. I might crosspost it to the stormwater forum. He has an industrial site on the ICW, and has to put together a SWPPP for it that includes an estimate of how fast an oil spill will travel down the intercoastal waterway, so he needs an...
I'm working in an application that's not explicitly marine engineering, although it has some similarities. My client will be anchoring floating debris collection rafts in active streams and rivers, and we want to do field testing of how much force is in the anchor line at various flow rates of...
Existing open topped cast in place box serves as an overflow structure for an outlet control. I want to add a baffle to catch oils and floatables. The design stage is going to stage up 2.5 feet above the box crest, so I need to set the baffle box far back enough so the gap between the baffle and...
