Today Caleb and Dr. Stonedahl showed Caleb Gibson what we have been working on so far this Summer, and we also took more data from the two Permeameters. In between our first and second run of the peremeameters the Humboldt one stopped running, so we were not able get any more data from it today, and we also noticed that there was air between the sand and the permeable plate in the permeameter, so we want to make sure that doesn't happen again.

We also went to lunch and met with the other groups in the SRI and we all presented our weekly updates to each other.

For the program we have worked on trying to find a better method for the blue detection, and still haven't made much progress on improving it. We think that we will try using separate methods for the dark sand and the lighter sand, to see if that will allow us to get more accurate results from the darker sand.

For tomorrow:
Run both permeameters.
    Hopefully we will be able to get all the measurements.
Work on program.

Today Caleb and Dr. Stonedahl took measurements from the Nicole permeameter and the Humboldt permeameter, and the values stayed pretty consistent. Even after we changed the level that the Humboldt permeameter was sitting at, it didn't have an effect on the values after we changed it back.

 

Caleb also began working on a program to test how well the blue detection in the timelapse pictures is working. First he had to go through a set of timelapse pictures and mark where they are blue, so that we could see if the blue detection is detecting the same spots in the original timelapse pictures are blue.

Differences in the initial and current timelapse pictures

For Tomorrow:
Run both permeameters.
Continue drying sand.
Finish blue comparison program.
Caleb can start working on poster and presentation.

Again, Nicole collected data on the Nicole permeameter and the new Humboldt permeameter. She taught Caleb the method so that he could gather data while she is gone. Nicole also created powerpoint graphics of the Humboldt permeameter to use for the presentation. Additionally, Dr. Stonedahl and Nicole discussed and planned the format of Nicole's final poster.

Humboldt Permeameter

Campus was having a crisis drill today while we were researching. Don't worry though Caleb, Nicole, and Dr. Stonedahl were not harmed. We did have to go under caution tape to get into Dr. Stonedahl's office. Because of the drill we could not get to our sand drying lab to check on our sand. 

Do not enter the chapel

Caleb worked on the program yet again with Dr. Forrest Stonedahl's help. Caleb also researched other methods of detecting the blue, but could not find any.

Today Caleb has worked more on the program, mainly working on making the code look nicer and not as much of a mess, but also testing methods to see if we can improve the blue detection. He also compared the physical, simulation, and XOR'd bitmaps with images to see how well it is matching up, and there tends to be extra areas in the darker sand that are identified as blue, so we need to try and eliminate that from happening.

A figure of the percent match for each frame.

Nicole has worked on parts of the presentation with Dr. Stonedahl. We also got our replacement tube for the Ordered Permeameter and got it put together and set up in the hydrology lab. We also worked on drying the sand more.

New Permeameter Setup

To Do:
Run the old permeameter and the new permeameter.
Create data sheets for the new permeameter in excel.
Print out more data sheets.
Make sure Caleb knows how to run the permeameter.
Continue working on program.
E-mail Dr. Lillis.
Continue drying more sand.
Avoid the Crisis Drill.

Hopefully we won't get shot.

Again Nicole collected data from the falling head permeameter and the Nicole permeameter. The Nicole permeameter cooperated a lot better today, so that was nice. Sadly, our falling head permeameter shattered our hearts today. When Dr. Stonedahl was cleaning it out the glass cylinder decided it was done with our research and broke into a lot of little pieces. Jokes on it though because we were still able to collect today's data. Dr. Stonedahl ended up finding two more glass cylinders to replace the fallen soldier. Nicole also calculated how much the Caleb permeameter cost and created more graphics for the presentation.

Gone but never forgotten

We finally received the Humboldt permeameter today. Funny story though... one of the tubes arrived broken. The permeameter gods were not with us today. Dr. Stonedahl sent a way kinder email than most would at this time to the company and they are shipping us a new tube. Hopefully we can figure out how to replace the tube when it arrives.

Today wasn't completely awful though. We finally started making progress on drying the sand. We are using heat lamps and the sun to dry out the sand. We will continue this process next week.

Drying the sand

Caleb fixed an error in his code. He also did more research on ways to compare the color values to determine if the cells are blue.

To do:

Figure out how to set up the fancy permeameter

Make more progress on the program

Today Caleb made more progress on the program, writing the code so that it will compare four windows centered on the midpoint between the center of the cell and each corner. He has also continued working on finding an improved method to detect the blue cells in the Physical model timelapse pictures.

Nicole continued to take more data from the falling head permeameter and the Nicole permeameter. We noticed that the Nicole permeameter's sand level was dropping a lot between data collection of heads A and B. Luckily, it was still above the head difference so we could continue collecting data today. Nicole also worked on the SRI official blog as well as the presentation.

At today's official SRI lunch we met the donor that makes all of this research possible. We again discussed the progress of our research.

Caleb refused to smile and HAD to have ice cream

After lunch we worked on ways to dry out the sand. We made a trip to Walmart and Menards to buy heat lamps and aluminum containers to help us dry out the sand. Fingers crossed that it works.

To do:
Pick up permeameter from post office
Continue drying out sand
Take more data points

Today a lot of progress has been made with the program. It can now loop through specified frames of the physical and simulated models, and compare them to see if cells are matching in whether or not they are blue. The code to determine whether or not the physical cells are needs more work on it, so that we can be sure it is giving us the proper values on all the frames. After this step we want to make it so we are looking at four total points instead of just the center point.

We weren't able to take measurements with the Nicole Permeameter today because it wasn't running properly when we went to start it. We then took our falling head measurements. Then, we got help from Kinesiology (Suzanne Wiese), to let us in the exercise physiology lab to use the scales so we could weigh the permeameters. After we measured them, we calculated the volume each of the permeameters could hold, and then we were able to calculate the mass of the permeameters with sand inside. (The sand still has not dried.) Nicole, Dr. Stonedahl, and Justin Keister played the Hyporheic Game. Then we tried to figure out t-tests. Put stuff in MATLAB.

We started the day off by running the Nicole permeameter. Then Nicole collected today's data from the falling head permeameter. Dr. Stonedahl then decided to go frolic in the flowers while Caleb and Nicole were hard at work researching. Unfortunately, our attempts at drying the sand did not work and we are still waiting for the mountain of sand to dry. Nicole finished powerpoint graphics of the PVC pipe permeameters today. She also made more progress on the presentation.

Nicole and Caleb "missing out"

Caleb made more progress on the program. He decided to use a window of twenty-one pixels with a cut off of -1 to determine whether or not it was blue for the simulated picture. He also decided to use a window of twenty-one pixels with a cut off of .05 to determine if the cell is blue in the physical picture.

We start today with running both of our permeameters, and finished three runs in the day. We also came up with new ways to dry out the sand. An excel sheet was set up to keep track of the cost of the permeameter. The presentation for the SRI has been started.

Progress has been made on the program. We're able to subtract one image from another to see if we're able to compare the two for which squares the Blue Salt Solutions have traveled to, we would like to improve on it more, but it's starting to get close.

Notes for tommorow:
Do more Permeameter tests.
Continue work on presentation.
Continue work on program.
Remove Herobrine.

We started the day off by visiting the dog group. They explained their protocol and practiced it on a few members of the SRI.

Then Dr. Stonedahl and Nicole collected data from the Nicole permeameter. After each run we have to wait an hour before we can collect data again. In the meantime, Dr. Stonedahl and Nicole collected today's data from the falling head permeameter test. Before lunch Dr. Stonedahl and Nicole collected the second set of data from the Nicole permeameter and set it up to run the hour during the lunch break. Tragically, when we returned from lunch we realized that the constant head flow was interrupted. Some sand ended up partially drying out because of the lack of constant flow of water through the permeameter, ending our data collection for the day.

Dr. Stonedahl and Justin

Caleb continued to work on his computer program. Dr. Forrest Stonedahl visited and was able to help Caleb with his program. Caleb also consumed three ice cream cones today during the course of two hours. Dr. Stonedahl came in second with eating two ice cream cones.

Today we began with setting up a table to write down data for our falling head tests, so that we could begin taking measurements. Caleb also began working more on his program, and eventually we had to go to lunch to meet with other groups at the SRI. At the lunch each group shared updates of the progress they have made on their respective projects. After lunch, we began taking measurements with the falling head tests and recording data. Our first run of measurements with it seem to be matching with previous runs, but we haven't done enough tests to be sure of it, yet. The constant head permeameter was also set up, and measurements were taken from it. At the end of the day we set both the falling head and constant head permeameters up so more tests can be run tomorrow.

Setting up for second falling head test

For tomorrow:
Continue working on computer program
Take measurements from both permeameters.
Fix constant head spreadsheet by adding meters to h
send permeameter back

Today Nicole and Dr. Stonedahl started the day off by noticing that the permeameter had leaked all night. We searched all over for the leak and found out that it might have been leaking in many places. The major leak was coming from a piece that we added a screen to this year to try to stop the flow of sand into other portions of the permeameter. It might have been from the piece being extremely hard to screw together and not having a tight enough seal. We also re-puttied the other pieces and that helped contain the leak. Nicole and Dr. Stonedahl also finished the permeameter today by adding a ruler. The permeameter is ready for business tomorrow.

Nicole and Dr. Stonedahl also put together the Hvorslev falling head permeameter test. It will be ready for testing tomorrow.

Caleb spent the first half of the day beginning a program to compare the blue dye from the simulated and physical runs last year. After some amount of time working on it, he realized that he chose the wrong image to select the coordinates from (it was a picture from before the camera was adjusted), so he had to go back and re-do the coordinates that will at some point be plugged into the program along with the time lapse pictures.

Dr. Forrest Stonedahl and Caleb

For Tomorrow:

Collect first data from the Falling Head Permeameter and the Nicole Method

Mail Back Permeameter

Make a list of supplies for putting together the permeameter

Caleb can continue working on program

Present to other groups at lunch

Today Caleb began working on marking pixel coordinates from one of last year's runs, so we can begin working on a program to compare the simulated and timelapse runs. Nicole and Dr. Stonedahl finished the design of the permeameter --- including designing new pieces to secure and keep the permeameter level. Sean, Noah, and Kris from galvin helped cut the pieces for it.

Drilling holes into wood

After setting up the permeameter, we found a small leak from the bottom. Rulers will still need to be attached to the tubing of the permeameter.

For tomorrow:

Wake up

Send permeameter back

Add rulers and levels to permeameter

Starting falling head permeameter measurements

Get started on programs for comparing simulated/physical runs from last year

Dr. Stonedahl is supposed to bring the Heaven Piercing Giga-drill.

Today was the beginning of the USRI. Caleb and Nicole started the day off right by both showing up late. Natalie also attended orientation and might be joining us. We started by testing Nicole's permeameter that we built before the school year ended. We are proud to announce that there were NO LEAKS!!! Then we went to Subway. After Subway we took a trip to Menards. We got the final materials for Nicole's permeameter today. Fun fact: If you ask a Menards worker where something is located they will most likely know the exact isle. Caleb glued the final PVC pipe pieces together. We then set up computers for the summer. We also attempted to put together the very expensive permeameter. It did not come with instructions :). When we called the company the worker thought we were stupid for asking for instructions. We are pretty sure that we ordered the wrong tube even though Dr. Stonedahl thought it might be wrong in the first place but still ordered it.

Write a blog post
Put the drain in permeameter
