This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sherry Chen (hydrologist) rather than just read about it. In short: Sherry Chen (Chinese: 陈霞芬) is an American hydrologist who worked in the National Weather Service (NWS) office in Wilmington, Ohio. She was accused of spying and arrested in October 2014.

Key takeaways

  • Sherry Chen (hydrologist) belongs to earth science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Sherry Chen (hydrologist) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Sherry Chen (hydrologist) from memory before moving on to harder problems.

Reference excerpt

Sherry Chen (Chinese: 陈霞芬) is an American hydrologist who worked in the National Weather Service (NWS) office in Wilmington, Ohio. She was accused of spying and arrested in October 2014. In March 2015, federal prosecutors dropped all charges against her without explanation before the trial began. Even with the case dropped, Chen was fired from her job in March 2016 for many of the same reasons that she was originally prosecuted for. In October 2016, Chen filed a case of wrongful employment termination to the Merit Systems Protection Board (MSPB). In April 2018, MSPB issued a decision stating that Chen was "a victim of gross injustice" and ordered the Department Of Commerce (NWS is an agency under DOC) to give her job back with back pay. In June 2018, DOC filed an appeal of the MSPB decision, but this has been delayed. In January 2019, with her case in an indefinite limbo, Chen's legal team filed a civil lawsuit against the U.S. government for the malicious prosecution and false arrest in the United States District Court for the Southern District of Ohio. The case was settled on Nov. 10th, 2022. Ms Chen was awarded $550,000 up front, followed by $1.25 million to be paid out by the US government over the next 10 years.

Background and employment in NWS Sherry Chen is a naturalized U.S. citizen born in Beijing, China. From an early age, she was interested in engineering, especially in the abstract nature of water and air. She earned advanced degrees in Hydrology in Beijing, married and moved to the United States to pursue a graduate degree in Water Resources and Climatology. After graduation, she worked for the Missouri Department of Natural Resources for over 11 years before moving to the Ohio River Forecast Center (OHRFC) of the National Weather Service in March 2007. Chen's primary work was to develop and implement the Ohio River Community HEC-RAS Model, which was the largest of its kind in the nation at that time. The goal of the computer model is to significantly improve flood prediction for over 2,000 miles along the Ohio River and its tributaries. The modeling effort is a critical part of the joint mission of OHRFC and the U.S. Army Corps of Engineers (USACE). Her team received the 2011 National Weather Association Larry R. Johnson Special Award for the "development of and operational success with the Ohio River Community HEC-RAS Model during May 2011 Ohio and Mississippi River flooding". Chen worked during a critical period of the record-setting flood event to get the best possible model results to aid the USACE in their operational decision-making process.

Federal prosecution and case dismissal Chen's case was triggered by her trip to Beijing to visit her elderly parents in 2012. Chen says that one of her relatives had a dispute with local government about a water pipeline and approached Chen for help since Jiao Yong, vice minister at China's Ministry of Water Resources, is Chen's former classmate in Hydrology. Chen met with Jiao for 15 minutes and told him about her relative's complaint. Towards the end of the meeting, Jiao said his office was trying to fund the repairs of China's aging reservoir system and would to know how this may work in the U.S. As a favor, Chen agreed to help. Once she returned to US, Chen searched the National Inventory of Dams database using a colleague's password he gave to her and sent Jiao some public websites. She also asked the chief of the water management division of the US Army Corps of Engineers (ACE), who said Jiao could talk to her directly. Chen then emailed Jiao to contact this colleague, without following up further herself. Not long after, this colleague reported Chen to the government security agency suggesting that she may be a Chinese spy attempting to gather U.S. Army Corps of Engineers water control manuals. In June 2013, Chen was interviewed for seven hours in her office by two special agents from the Department of Commerce. Chen says she tried to cooperate and told the agents everything she knew, but they later claimed that Chen was lying to federal investigators because she misremembered when her meeting with Jiao was, stating 2011 rather than 2012. On October 20, 2014, six FBI agents took Chen away in handcuffs in front of her colleagues. The Department of Justice (DOJ) issued an indictment with a punishment of up to 25 years in jail and $1M in fines. The original charges included accusing Chen of stealing data, intentionally exceeding authorized access to a database and making two false statements to investigators. Chen's lawyer, Peter R. Zeidenberg, a partner at Arent Fox in Washington, D.C., defended her case. He found fatal flaws in the case and filed three motions pointing out these flaws and requesting that the DOJ have the case dismissed. The prosecutor went back to grand jury to fix the problems and came back with eight charges and added another prosecutor on his team. After extensive interviews of witness including almost all of Chen's coworkers, search of the history of Chen's bank account statements over twenty years since she came to the US, personal and official email accounts, computer activities, the government decided to drop all the charges against Chen in March 2015 without explanation.

Worked examples

Example 1 — a first encounter with Sherry Chen (hydrologist)

Start with the simplest possible case. Write down what Sherry Chen (hydrologist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sherry Chen (hydrologist) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sherry Chen (hydrologist) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sherry Chen (hydrologist)

In research
Sherry Chen (hydrologist) appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Sherry Chen (hydrologist) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Sherry Chen (hydrologist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics American hydrologists, Espionage in the United States, Living people, so understanding it makes those chapters shorter.
In everyday life
Look for Sherry Chen (hydrologist) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
