Flushing Water Mains for Sediment

I saw this article talking about how the town Jackson MI was going to flush the water mains for iron and sediment. The water is still safe to drink, but could be discolored, and people are recommended to not wash their clothes with it. Since I study water, I was interested in the need to […]

Sediment in Venice

Inspired by my upcoming trip to Italy, my discussion this week looks at sediment in a lagoon in Venice. Venice is a city in Northern Italy that is made of many different islands that are connected by canals and bridges. The Venetian Lagoon is the overall term for the area encompassing Venice. Humans have had […]

Filtering Croton Water

Yesterday I visited the Old Croton Aqueduct with my club (Soil and Water Conservation Society).  We were able to walk into the 41 mile aqueduct built in the 1800’s, and see how it worked, and learn some of the history behind it. It was New York Cities first clean source of water (after they polluted […]

What is Marine snow?

Marine snow – though it sounds like magical ice snowflakes drifting through the ocean is actually made up of many more particles than its land counterpart. When things happen in the ocean such as dying/decomposing animals particles of these events break up, and slowly drift down to the sea floor. These biological components and additional […]

Gleying

(http://2.bp.blogspot.com/_6CGtXcavSuo/S-wH-dT28nI/AAAAAAAAAS0/WiTeWCZFDOQ/s1600/gleyed+soil.JPG) The image above is an example of gleying in soil. What is gleying? It is when low oxygen soil conditions (such as a high water table) cause iron and manganese to reduce, and make the soil gray. There are some cases where plants grow in soils that have low oxygen, and the roots that go […]

Major Rivers without Deltas

  Narmada River in India The Narmada River flows east to west, and is 815.2 miles long. It  originates in a small reservoir called Narmada Kund at a fairly high elevation, and empties into the Gulf of Khambhat. The high source elevation gives the water a lot of force, as the flow of the water […]

Yellow River Delta

I learned ( In my Natural Resources of China class) that much of the lowlands of China are a delta formed by the Yellow and Yangtze Rivers in China. This is where they do much of their agriculture, because most everywhere else in  the country is too mountainous. The Yellow River Delta is a river […]

Rakaia River Timelapse

https://earthengine.google.com/timelapse/#v=-43.53499,171.73082,10.818,latLng&t=0.00 After being inspired be a class discussion on rivers, and Google Earth Engine, I decided to look at rivers in New Zealand, and make a timelapse of its changes over time. I looked at the Rakaia River, which seems to be both meandering, and braided in parts. I think this helps exemplify that identify […]

Dust Storms

Dust storms are to deserts what floods are to rivers. They are quick, massive, and dangerous.  Like floods, they can also cause destruction to infrastructure, including homes, and people have been killed by them (Giuggio). However, the main danger presented by dust storms is longer term than being buried under piles of sand. Dust storms […]

Plinthite

I learned about this mixture in my soils class last week, called plinthite. I am not sure whether or not it is considered a rock, or soil. It is a mixture of clay, quartz and other minerals that hardens when it gets wet, supposedly irreversibly hard. I find this rather interesting, because I would think […]

Sand for Snow and Ice

Portland begins cleaning sand and gravel off roadways after recent snow storm This link brings you to an article about the Portland Bureau of Transportation, and how they use sand and gravel to provide traction for cars on the road, and the cleanup afterward. While cleaning up the sand and gravel may seem tedious, I […]

Parabolic Dunes

https://phys.org/news/2017-01-invasive-sedge-dunes-native-grass.html I saw this article about invasive species being better at protecting a dune from erosion than native species, and it got me to thinking. When we were outside Wilbur Cross we talked about two different types of dunes, barchan dunes, and parabolic dunes. Barchan dunes move with the limbs first, while parabolic dunes move […]

Stone Candle Holder

My parents just got back from a trip to Arizona, and the Grand Canyon. They brought me back this stone candle holder. I find the different layers incredibly interesting, but I’m wondering what all the dark lines between the different sections/top could be-they are slight ridges that stick out of the side of the holder. […]

The Grand Canyon, From the Sediment Perspective

Madeline Kollegger and Taylore Grunert The Grand Canyon is known around the world for its incredible layers, and defying depth. It formed from the bed of the Ancient Colorado River, as it wound around the plateaus in the Colorado Plateau Province. The water in the river, and the sediment it carried wore away at the […]

Sediment: Not Good To Spill

The sediment (which was accidentally spilled) was laden with heavy metals, and was part of a dam rehabilitation project upstream. As the fine grain sediment settled, in some places it made […]
