Engineering with Replicas to Save Dams

 Engineering with Replicas to Save Dams


Michael Johnson, Utah State University hydraulics engineering professor, and other engineers created the Oroville Dam replica.

***Originally, I put "Michael Johnson" is enclosed in commas but didn't like the way it was shown. Normally in work like this, the person's name is first and their title is in commas.; Utah State University hydraulics engineering professor Michael Johnson and other engineers created the Oroville Dam replica


Michael Johnson created this dam replica to examine one of two channels that run the width of the spillway to allow air into the water to prevent bubble formations that can damage the concrete spillway of the real dam.


These new channels, called aerators, cost $300 million to reconstruct and will be applied by November when the winter rains and snow come to increase the water's volume in the dam.

***I just made a small change at the end. I switched the words around and removed some while keeping the same meaning.; These new channels, called aerators, cost $300 million to reconstruct and will be applied by November when the winter rains and snow come to increase the volume of the water in the dam.


The simulation of the 100-foot (30-meter) long replica, that took 40 days to build, begins with a crew member opening a large valve that sends water down a chute modeled after the spillway and crashing into blocks that disperse and send waves to a replica of the river.

***I enclosed "that took 40 days to build" in commas. That was like side information or an appositive which always are separated in the sentence by commas. And I removed "it" at the end, it was not needed. ; The simulation of the 100-foot (30-meter) long replica that took 40 days to build begins with a crew member opening a large valve that sends water down a chute modeled after the spillway and crashing into blocks that disperse it and send it in waves to a replica of the river.


With the help of the simulation, hydrologists can calculate the velocity of the water and track down how much air is going into the water, which can lead to the complete testing of the aerators.

***With this sentence, I just wanted to "polish" it. Change phrasing and words to make it more appealing. For example, I gave the transition some help.; With this simulation, hydrologists can calculate the velocity of the water and track down how much air is going into the water, which leads up to the complete testing of the aerators.


By utilizing this new type of technology, there will be fewer floods, evacuations, and less anxiety about the disastrous effects of inefficient dams.

***The beginning of this sentence or the one before it can be changed. If you already used it once, there no need to use it twice. So, I found a replacement for this beginning transition. And I thought "inefficient" would be a better word than "faulty."; With this new type of technology, there will be fewer floods, evacuations, and less anxiety about the disastrous effects of faulty dams.

CTE in Football

 CTE in Football ***The title needs something more descriptive than "Football Disease." It doesn't tell the reader anything about what the passage is about. In fact, football disease could mean anything. That's why it is important to be specific and detailed. The new title "CTE in Football" gives a different light to the passage. The reader now knows what the passage will be talking about.; Football Disease Football is a very dangerous sport that involves with uncountable injuries. However, one serious injury can cause brain cell damage and death: Chronic Traumatic Encephalopathy, or CTE, a degenerative brain disease that affects the brain over time. ***I decided to combine these two sentences since they are both short and simple. The first sentence remained to same then a colon was added to reveal what this injury is and what it does.; However, one serious injury can cause brain cell damage and death. Chronic Traumatic Encephalopathy(CTE) is a degenerative ...
