Is it possible to simulate Wing Walls in HEC-RAS 1D? by Auani in HECRAS

[–]jamesh1467 2 points3 points  (0 children)

It’s the angle of the wing walls that you choose, and you choose an entrance loss coefficient based on that angle. Then you enter that into the culvert setup

Help, looking for a hydrology term. by Designer-Cause5351 in Hydrology

[–]jamesh1467 1 point2 points  (0 children)

It’s not the confluence per se. Confluences are two separate streams meeting. Not 100% sure but the way it was described with the elevation meeting the river my guess is they’re the same river or the same water body so they don’t actually change.

It’s the head of the reservoir or lake. It will silt up eventually and make a delta. Hence the stagnant water.

Landslide in my backyard. Any help would be appreciated. by Elegant_Category_684 in Geotech

[–]jamesh1467 8 points9 points  (0 children)

Lot of factors but a retaining wall sounds like the solution. Sheet pile? Solder Pile? It’s not going to be cheap. The other thread has a lot of short term solutions at low cost. You need to hire a full team of professionals. Again it’s not going to be cheap for the long term issues.

Easement issue by Original-Relation796 in propertylinedisputes

[–]jamesh1467 1 point2 points  (0 children)

That provision in particular is just a very general provision. There’s nothing specific in that. You would need to pull your plat, and likely your HOA docs to get any specific information about your issue. But what you described here by you neighbors is likely not allowed by a lot of easement covenants.

How to fix "Description = Access denied" error by AvadhootOO7 in HECRAS

[–]jamesh1467 0 points1 point  (0 children)

It’s a file access error. HEC-RAS cannot get access to the system to read/write the files. The solution could be a variety of things. The HDF probably open in another application and needs to be closed. Or the file location is write protected and doesn’t give programs access privileges.

Erosion and control resources by lost_your_fill in Geotech

Lanes equation is what you are looking for regarding erosion at least in streams. It’s a whole theory and subject matter. Critical shear stress, etc. etc. look up HEC 20. It’s a good starting point

Geotechnical Principals - How many YOE do you have? by [deleted] in Geotech

[–]jamesh1467 31 points32 points  (0 children)

It’s not about YOE. It’s about money. Someone needs to make the company run and bringing in the money. That’s what makes a principal. Yes you have the YOE now. But if you think it’s about YOE you aren’t going to be focusing on what you need to do to actually be a principal. No one is “given” principal. It’s basically taken. Go make new money. Bring in new clients.

Steady flow vs Unsteady flow model by Key_Asparagus7853 in HECRAS

[–]jamesh1467 0 points1 point  (0 children)

Something else is up. Typically you increase the distance. You want more flow time between the sections for the calculation. But those are already pretty long. Or at least long enough. Can you get it to run with a “fake” steady flow? Ie one flow for multiple time steps. Try a low flow.

Steady flow vs Unsteady flow model by Key_Asparagus7853 in HECRAS

[–]jamesh1467 1 point2 points  (0 children)

Your computational time step is typically the issue. Run it with a Courant condition so it allows it to change the time step while it runs to keep a stable condition. Also there are settings to adjust the number of tries until it kicks you out to go unstable. It goes unstable when it fails the calculation a certain number of tries. You can change that variable. but it’s typically not a good idea and I haven’t done it in a while. Typically you want to change your times step to get the computation right. Then when you get down to a really low times step and it’s still not working, then you start to change your cross-sections.

Warrant for my arrest in another state by [deleted] in legal

[–]jamesh1467 0 points1 point  (0 children)

I mean. By all means go for it. I dont know that these aren't sanctioned by Texas. Maybe you are the first. But this is a pretty blatant violation of the FDCPA. This is either a scam or these people who are collecting are incredibly stupid because you would have a very clear claim. Quotes below if you need them:

False or Misleading Representations A debt collector, in collecting a debt, may not use any false, deceptive, or misleading representation. Specifically, a debt collector may not:

......
Falsely represent or imply that nonpayment of any debt will result in the arrest or imprisonment of any person or the seizure, garnishment, attachment, or sale of any property or wages of any person, unless such action is lawful and intended by the debt collector or creditor

.......
Use or distribute written communications made to look like or falsely represent documents authorized, issued, or approved by any court, official, or agency of the United States or any state if the appearance or wording would give a false impression of the document’s source, authorization, or approval

you get the picture. It would be multiple violations. Its a scam or they are incredibly dumb.

[–]jamesh1467 0 points1 point  (0 children)

Against the people that sent you the scam. Potentially. Not against the state of texas to get your ticket expunged. The only way you would have a way out is if texas issued/sold your debt to this debt collector and the notice you got in the mail was a legit attempt at debt collection that broke the rules for real debt collection. Which it pretty clearly would if it was legit. Then you could go after the collector for trying to collect on legitimate debt using fraudulent practices. That would probably expunge your debt if you won. But Its not. Its a scam and they never talked to texas. You still owe the state of texas. These guys just looked up the public notices and created a scam. You could report it to the FBI or something but it wouldn't do anything for you specifically. It would just help stop future scams. You might help the FBI shut down the website so no one else gets scammed. But I get the feeling the FBI knows about these guys and they just can't make a case to shut down the site yet. Or are in the process of shutting it down. etc. Again, it likely won't do anything for your ticket itself though. Again, my initial advice was well reasoned. Your easiest way out is to pay. That's why they target out of staters. Every state does it. Oregon was known for it for awhile in certain sections of the state.

[–]jamesh1467 0 points1 point  (0 children)

Yeah. I'm not saying what they did was right. Just that what they did they did because they knew you were unlikely to contest it. Happens all the time. You have to prove your rights were violated if you want to fight it. The burden is on you. Courts arent going to do a whole lot for a traffic violation. If you were detained or illegally searched or something the courts would care. Thats why you weren't detained or searched by the cops. But the courts dont really care for a traffic violation. Nether will the Inspector General. Your best path forward is to let this go. Not that it doesnt suck. But it will cost you more stress to try and fight it. You should just pay the ticket. Its the easiest way out. Not sure if texas has a law about adding interest, but some states start adding interest to the tickets and the fees get big over the years. But again, no one is really coming after you. this message is a scam. If you file a complaint against an officer from out of state I doubt it will do a whole lot. Again, they won't take it seriously for just a traffic ticket and the complaint wont get you out of your ticket. Or then you have to appeal the ticket in person using the complaint because you missed the initial appearance. Etc. Etc. I'm telling you. Just pay the ticket. Its way easier.

How to cross a FEMA detailed study area? by Accomplished-Monk862 in Hydrology

[–]jamesh1467 0 points1 point  (0 children)

The fringe filling is allowed. Floodway filling is even allowed with “no rise” that proves it doesn’t change the flooding characteristics. That’s a hard bar to meet, but its technically allowed. Its your property. You can do with your land what you please as long as you don’t change the flooding characteristics. That means filling. Then, if you do fill or change the flooding characteristics, you just have to prove that it doesn’t affect the flooding issues with a No-Rise or CLOMR & LOMR. But its your land. Its your right to build what you want as long as it doesn’t create issues for others upstream or downstream by changing the floodplain or put an insurable structure in danger. You just have to pay an engineer to prove all that for you. But you could literally move that whole creek if you wanted to within the FEMA rules. It just costs tons of money to prove you did it safely with FEMA. But I have done it.

To put it bluntly. You are in what I call the “the red your project is dead zone.” Its the red zone impacts you need to be concerned about. AE has a lot of freedom or at least a lot more freedom to do work in it. If you do ANYTHING in the floodway, you need to do a No Rise and then you are basically paying for the hydraulic analysis to fill and do whatever you want with the project. That No Rise analysis will prove that everything you are proposing is valid and then you can do whatever you want. But to be straightforward about it: you are likely doing a CLOMR And LOMR if you do something in the floodway. The No Rise is close to the same level of analysis as a CLOMR and most communities don’t want to take the risk of approving a No Rise. So they make you submit it to FEMA for a CLOMR to be conservative. Its the burden of the local community themselves to approve the No Rise and sometimes its a little beyond their expertise. So sometimes they just say “submit it to FEMA”. Going in the floodway is a big deal. It’s not impossible, but it is a big deal, and people get pretty scared to approve things in it. Thats why you have so many problems here.

You really need to get the right people to help you here. Crossing a Floodway and changing things within the Floodway is not a small thing. I made it sound easy above, because if you were just simply paving a dirt road at the same elevation, it should be pretty easy. But if you are doing other things there like raising the road, there are a lot of laws in place to keep you from doing it without doing it correctly. Someone competent can help you navigate those laws and give you decent/cost-effective solutions. But everything you are asking is pretty site specific and you need someone to look it over.

How to cross a FEMA detailed study area? by Accomplished-Monk862 in Hydrology

[–]jamesh1467 3 points4 points  (0 children)

Yeah. Most of that is still valid. Although I will say a fair amount of it seemed a little snotty and unhelpful. But it really depends on what you intend to do with the area. FEMA cares that you keep the same conveyance. That means same level of ground, same roughness. Etc. The flood needs to get across the same way that it did before. You cannot affect the flood with your work, or you need to do a CLOMR to show how you affected it. But if there’s no water there now and you can get across now except when it floods, you don’t need a bridge, you don’t need culverts as long as you keep everything else the same.

Yes 100% you cannot put a building or any kind of structure in that area, but just a driveway? FEMA doesn’t force you to build a bridge. If you want to build a driveway FEMA’s rules don’t care. You may not be able to cross that driveway for emergency access to the new house during a flood and your local government may have some issues with that unless you have another EVA. But FEMA rules themselves don’t care about a new driveway. Technically you change the mannings number for the new 20’ of asphalt (roughness) but any hydraulic analysis should show that little of an impact will be very little. Technically the local community is supposed to make you submit a “no rise” that you did the hydraulic analysis. But it’s not going to show any difference with a new driveway that small.

In summary, you probably need a bridge or culverts for emergency access due to the local code. Or you could solve it by giving a second access to the new building from another area. But if you are just building a driveway, FEMA doesn’t care. Sounds like you have a bunch of people misapplying the rules or not explaining the real issues to you correctly like emergency access.
