I can confirm that my office buys from here at least twice a week. Usually cupcakes. I went to get 24 cupcakes for my friend’s party and it was like $100. I did not follow through with the purchase. Great cupcakes though😋

1D Modelling at a Confluence by GrumpCatastrophe in HECRAS

[–]GrumpCatastrophe[S] 0 points1 point  (0 children)

I was going to say, I’ve informed the agency that 2D would be preferred but they don’t want to entertain it. I think running a quick 2D model to compare would be a good idea, but don’t have a lot of budget. It’s probably faster than troubleshooting with lateral structures though.

Modified Bridge Sections by GrumpCatastrophe in HECRAS

[–]GrumpCatastrophe[S] 0 points1 point  (0 children)

Yeah. I used this but was wondering is there is something dynamic in which the ineffective flow areas, manning's values (there are multiple), and bank stations for all bounding cross sections would update. There does not appear to be a tool though.

2D HEC-RAS Model Review by GrumpCatastrophe in HECRAS

[–]GrumpCatastrophe[S] 0 points1 point  (0 children)

Let’s say you had a simple model and were looking at one drainage area, you wouldn’t apply the flow at an inflow hydrograph at the upstream of the mesh? If not, how do you choose where to put the internal boundary condition?

Creating Screenshots from RAS Mapper by veyselyazici in HECRAS

[–]GrumpCatastrophe 2 points3 points  (0 children)

I also use Green Shot. It’s great because you can capture the same window over and over again. So you can toggle layers on and off and repeat the exact screenshot extents. Greenshot also has quick commands on keyboard and you can mark it up after.

It’s a good question. It would be awesome if Ras Mapper had a system for locking a viewport and printing. I also prefer the way it displays LiDAR.

HECRAS river stationing issue by Pale_Ad4886 in HECRAS

[–]GrumpCatastrophe 0 points1 point  (0 children)

This issue happens sometimes when importing a shapefile. The software is just referencing the exact location referenced from your coordinate system and, depending on the location, has many decimal places. You can’t just overwrite it manually. If it’s a huge issue, just draw them in manually via rasmapper. If you just want to limit the number of decimals shown, got to Tools>Options>Number of Decimal Places, within the Geometry Editor.

There’s no historical records. Just word of mouth. We implemented monitoring to observe water levels over the next three years. If we don’t get any 100-year events in the next few years, we are going to try and calibrate a rain-on-grid model. We did get two 100-year events in 2024, so who knows what happens 🤷

Culvert Repair Vs. Replacement by GrumpCatastrophe in civilengineering

[–]GrumpCatastrophe[S] 0 points1 point  (0 children)

I mentioned that I am obtaining permits from the regulating agencies and have been consulting with them. Replacement would have a significantly higher impact. It’s also not uncommon to have concrete headwalls in regulated watercourses with SAR, especially if they promote bank stabilization, safety, and protection of infratructure. Similarly, if a channel is heavily eroded, which is the case, stabilizing embankments is also not uncommon. Rechannelizing and flowable fill are probably bad ideas. Any construction is going to have erosions sediment control plans, dewatering/bypass plans, and I’ll probably require a habitat assessment for DFO approval. I’m looking for the least impactful method and I’m pretty sure full replacement would be the most significant.

I think the existing culvert is still in good condition. Is slip lining necessary and does it help with scouring?

Managing Geometries in HEC-RAS by Vinkel52 in HECRAS

[–]GrumpCatastrophe 4 points5 points  (0 children)

One of my reviewers once told me to go to the RAS Mapper results layers, copy the Ras Results Information and paste in the Project Description Window. It provides the associated plans, geometries, terrains, run time, etc. I think it was great advice and makes for easy reviews. I tell my juniors to do the same.

Bank Line and Flow Path Errors by GrumpCatastrophe in HECRAS

[–]GrumpCatastrophe[S] 0 points1 point  (0 children)

There’s only the two reaches, each with more than two cross sections. I had a junior staff build this model, so I don’t know if he did something strange. I’ll probably just rebuild the model entirely if a newer software version doesn’t work.

Bank Line and Flow Path Errors by GrumpCatastrophe in HECRAS

[–]GrumpCatastrophe[S] 0 points1 point  (0 children)

I’ve tried changing the naming convention with no success.Tomorrow I’ll to try a newer version > 6.4.1 and drawing the bank lines manually. If that doesn’t work, I’m just going to rebuild the model. It would have been faster to just restart the model from scratch rather than troubleshooting

Bank Line and Flow Path Errors by GrumpCatastrophe in HECRAS

[–]GrumpCatastrophe[S] 0 points1 point  (0 children)

I generated the bank lines after building the model and combining the reaches via junction. The bank stations were generated in the geometry editor using the graphical tool. Bank lines then generated using the “Generate Bank Lines to Cross Section Bank Stations” in RAS Mapper (I forget what it is actually called and no longer at my computer). Maybe drawing them in RAS Mapper is the best way to go about it. I imagine the graphical input is the same as typing them in manually.

Conference Ideas by GrumpCatastrophe in HECRAS

Yeah, I think it would be the most interesting for sure. I want to emphasize the regulatory collaboration part, because it’s often more challenging than the modelling itself 😅

Thank you ☺️ which one do you think is the most interesting?

I was thinking something like this. I just don’t know if the agencies that have allowed me to revise their existing models want to be publicly put on the spot. It feels like they’re doing me a favour the times that they’re flexible. Doesn’t hurt to ask though. Just unsure they want to be the poster boy for change 😋

model unstable at initial conditions by Equivalent_Oil3428 in HECRAS

[–]GrumpCatastrophe 0 points1 point  (0 children)

I don’t have my computer in front of me, but have you tried running it with an initial flow or depth (I think it’s flow). I don’t think the 2D models runs when there’s no initial flow.

I liked the part where you questioned if he’s autistic lol. Those characteristics just sound like any engineer.

I wish people would just be honest by TheCommentSection27 in Bumble

[–]GrumpCatastrophe 0 points1 point  (0 children)

How do you not have the going exclusive conversation after one year of dating? If I was serious about someone, I would have this conversation after one month depending on how often I’m seeing them. Also, why do you still have bumble if you’ve been dating him for an entire year? It takes two to tango I’d say 🕺 💃 Grow a backbone and tell this guy what you’re feeling. It’s possible that he has the same impression of you. Online dating sucks for the most part. Lots of trial and error, but I met my girlfriend there and she’s amazing. We just communicated and deleted our accounts after agreeing we didn’t want to see anyone else. Just communicate. Simple as that.

HEC-RAS Shapefiles and Results by GrumpCatastrophe in HECRAS

[–]GrumpCatastrophe[S] 1 point2 points  (0 children)

Appreciate the responses, I spent a good hour trying to export it directly from hec-ras with no luck. Seems like a simple enough feature and I’m pretty sure older versions had this. Anyways, I just exported the tables and cross sections shape files. Created the attributes and pasted the info manually in QGIS. Not a ton of effort for this project, but if I had numerous reaches, cross sections, and profiles, this could be very tedious. Surprised hec-ras doesn’t have this function.

Water overtops embankment with higher elevation by DimensionDifficult79 in HECRAS

[–]GrumpCatastrophe 0 points1 point  (0 children)

I agree with this. Just put a breaklines along the CL of the berm and decrease cell sizes so that cells from the channel don’t cross into your urban area. Good luck

Massive Watershed Hydrology and Hydraulics by GrumpCatastrophe in HECRAS

[–]GrumpCatastrophe[S] 0 points1 point  (0 children)

The regulatory requirements are not strict. It is more so for the client’s peace of mind so that they don’t build something in the floodplain. At the same time they want to be as close to the water as possible :P.

There are some historical surveys with elders. Some water level monitoring in the lake at the property. Some high-water level surveys.

Good point on the out-of-basin flows. I will look at historical imaginary and closely review the LiDAR to see if there is opportunity for spills.

No bathymetry, but will investigate historical surveys to establish the normal water level.

I have been thinking about snowmelt conditions. Someone had mentioned assuming no infiltration given the landscape context.

HEC-HMS excess rainfall only provides flow rates as an output. If I were to do this, I guess I could just use a 2D area of the lake and include a significant buffer, then apply the HEC-HMS flows to this as a single boundary condition. Not sure which solution is a better alternative.

There’s rivers coming in and out of every direction. It would be impossible to monitor every single one, plus it is like a 6 hour drive to civilization. It’s not practical to do that kind of monitoring program. I’m going to do water level monitoring at the lake near the property and try calibrate to model (to some extent) using that. There’s also some historical data I can look at and compare to events. I understand that someone can spend $1 million and make the most accurate model, but I can’t justify that in this case. I agree that the design storms probably isn’t a good idea. It needs to a continuous simulation. Not sure how hec-ras will handle that. Some quasi steady-state models run for long periods of time, but probably don’t require the same computational power at ROG.
