CivE Week 9: The last week in the lab!

Hello there!

As week 9 gets under way, we are finishing up our analysis and making wish lists of everything we hoped we could have done with our projects. On Monday we met with our advisors to discuss a ‘stopping point’ for the summer. Although analysis never finishes, we have set down the boundary for how far we can take our projects in the time we have left. By mid-week, we will all have drafts of our final papers and by this Sunday, everything will be complete. The summer is coming to an end and it is bittersweet. 

I have definitely enjoyed my time here, and I plan on making the most of the last 12 days I have left. These last few weeks are sure to be packed full of adventures and fun as the festival and fair season continues going strong.

Francesca in Loring Park!

This past Saturday (8/2) I spent the day with Francesca at the art fairs around Minneapolis. We really enjoyed ourselves at the Uptown and Loring Park Art Festivals. After a full day admiring art in the outdoors, we headed inside to see fellow intern Jabari Jones play trombone with his band. Our advisor, Prof. Kimberly Hill, and her family were at the concert as well. It was a lot of fun to see everyone outside of the working environment!

Later this week, I will be presenting my poster at a research expo and the whole group will be taking a trip to University of Minnesota Duluth for a trip on the Research Vessel Blue Heron. I’m sure someone else will post about that when it happens!

Week 8 at CivE: The Rush to Finish has Begun!

As week 8 gets underway, we are all feeling the pressure of finishing up our analysis and experiments. I will be participating in the Summer Undergraduate Research Expo next Thursday in addition to our REU poster presentation.  This week it is time for me to buckle down and interpret my data so I can be ready to print my poster early next week and prepare for the expo!

Despite the work that needs to be done, we took a break yesterday to go on a field trip to Northfield, MN. We visited Carleton College on a private tour led by our very own Jabari Jones. The tour included walking through the arboretum, visiting the Geology Department, and searching for fossils in a shale outcrop. See below for some pictures from our adventure!

CivE Week 7 already?

Hey All,

It has been a while since I’ve posted, but here’s a quick update from the CivE building! We are all furiously working on analyzing our data. No one has used the specific code that we are using before in this research group, so we are slowly finding our way to the end together. velocityandbins

 

Last weekend, we also made a trip to First Avenue for a concert and to the Como Park Zoo and Conservatory!

Week 4 at CivE

Hey there,

I hope you all enjoyed your long weekend and had a good Fourth of July holiday! We certainly took advantage of our day off and had some adventures. A group of us decided to spend the day at Lake Calhoun. Although the weather wasn’t the best, we still enjoyed ourselves and took a swim. After a long day at the lake, we went to Sebastian Joe’s for some ice cream.

fun in the sun! 7_4_2014

(don’t worry, Francesca doesn’t always look that scary!)

We then went to see fireworks by the Stone Arch Bridge.

At the lab this week, we did some MATLAB and then decided to do an experiment with glass beads. We spent yesterday afternoon dipping beads in glycerin and then washing them off. We want to see if having the beads in glycerin and then washing them changes how they act in our flume. We are currently letting them dry, but hopefully by tomorrow afternoon we will have an answer to our questions!

Next week we should have some graphs and results!

Civil Engineering Week 3!

 

 

 

 

Hello!

Week 3 has ended and we are already in the midst of week 4! Last week we worked a lot with MATLAB to track our particles through the debris flow. We are still working on the analysis and simultaneously taking more data!

coffee at the mall                                                         During the weekend, we made a trip to Mall of America and spent some time wandering around the mall!                                          enjoying the view                                                        Monday evening we were able to attend a lecture by Dr. David Sedlak at the Science Museum of Minnesota. The lecture was on the different types of water systems we’ve had in the past and how we should look to improve them for the future. It was really great to hear someone put all of my classes together in a cohesive lecture!

After the lecture, we went on the the balcony of the museum and were able to see all of the flooding that is currently happening in St. Paul (above).lacCore tour                                                          Today we took a tour of the LacCore labs and were able to see how they analyze core samples!

Hopefully we’ll have some results to show you next week!

Week 2 at Civil Engineering!

This past week has been quite exciting! We ran more debris flow and sediment transport experiments. In both set-ups we were able to capture some high-speed video footage. Hopefully by the end of this week we will have had a chance to take that video footage and analyze a bit of it. I’m really excited to see what type of data we have so far!

Outside of lab we made a trip to Target Field to watch the Twins play. For some of the people on the trip, it was their first time actually being at a game!

Take a look below for some cool pictures/videos of the past week!

An Update from the Civil Engineering Building!

Hello! My name is Teri Oehmke and I will be one of the writers of the blog this summer. I am working on the debris-flow experiments in the Civil Engineering building at the University of Minnesota Twin Cities this summer.

Since the summer has only just begun, we haven’t had that many adventures so far, but I’ll fill you in on what we have done.  After orientation, a few of the interns decided that we need bikes for the summer, we had some fun going around to different stores to try to find bikes that were in our price range (cheap) and then pumping them up and getting them road ready. We still need to buy lights for night time riding, but we’ve enjoyed exploring the city with them during the day!

We also had a chance to do a few example experiments in the lab. We’ve run one day of debris-flow experiments and two days of sediment transport experiments. The debris-flow experiments basically consist of us weighing masses of beads to act as the debris-flow (supply) and another mass to act as an erodible bed. We then release the supply over the bed and see how much of the original supply is deposited on the erodible bed and how much of the erodible bed ends up in our tray at the end of the slope.

The sediment transport experiments deals with the relationship between the flow and the transport of a pebble placed at the bed. We played around with the weirs to change the flow height and speed and discover how different speeds affect the movement of the pebble.

We’ve also had some time to visit local events going on in Minneapolis. Last week we participated in the Northern Spark art festival. Despite the rain, we still had a great time.

That’s all I have for now. Stay tuned for more adventures next week!
