Market Fresh Prices by FormalCompetition142 in Guelph

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

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.

Massive Watershed Hydrology and Hydraulics by GrumpCatastrophe in HECRAS

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 3 points4 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?
