A leader in Texas water management

Latest Zhang project will help Texas improve water supply reliability, reduce flood damages

2023-12-01

(Press-News.org) A University of Texas at Arlington civil engineer is leading a statewide initiative to use more accurate forecasting to guide reservoir storage and release to improve water supply reliability and reduce flood damages.

Yu Zhang, a UT Arlington associate professor in the Department of Civil Engineering, is heading a new project—“Advancing Forecast-Informed Drought Planning for the West Gulf Region Through Integration of Climate Forecasts and Predictions of Reservoir Water Balance Predictions”—funded by the National Oceanic and Atmospheric Administration (NOAA)’s Climate Program Office. UTA received nearly $560,000 of the $719,000 grant.

Zhang is helping the state of Texas adopt what’s called Forecast-Informed Reservoir Operations (FIRO), in collaboration with Texas Water Development, U.S. Army Corps of Engineers, NOAA, the National Weather Service and the U.S. Bureau of Reclamation (USBR). Successful implementation of FIRO, according to Zhang, is predicated on accurate forecasts of reservoir inflow across a range of lead times, including at seasonal time scales of three to nine months.

“We want to introduce forecasts from dynamic climate models to complement and expand current climatology-based ensemble forecasts,” Zhang said. “We will develop forecasts for water withdrawals, diversions and lake evaporation to better represent weather/climate varying water demand.”

Zhang said the results of the research should inform the development of FIRO strategies and implementation of drought measures. The project also contains a dimension of informing USBR on its diversion project that supplies water to New Mexico and Texas. The ultimate aim is to help address water supply challenges in those two states.

Zhang is a leader in Texas in water management projects and developing better weather forecasting models. He is working with the General Land Office to develop a sediment management plan for the state, which includes assessing the amount of sediment transported from Texas rivers into the Gulf of Mexico. He also is working on a NASA-funded project to help forecasters better predict extreme weather events using a variety of existing NASA data sources.

Public gardens contribute to invasives problem

2023-12-01

Botanist Denis Conover does not have to go far to study the growing problem of invasive plants. During an autumn stroll outside his office at the University of Cincinnati, the biology professor pointed out numerous examples of nonnative, invasive species in campus landscaping. “This is winged euonymus, otherwise known as burning bush. And here is Chinese silver grass. It’s a popular ornamental, but the seeds are dispersed by the wind,” he said. And there were many others: English ivy, wintercreeper, Callery pear. For his latest study published in the journal Ecological Restoration, he and his students examined the impact ...

A color-based sensor to emulate skin's sensitivity

2023-12-01

Robotics researchers have already made great strides in developing sensors that can perceive changes in position, pressure, and temperature – all of which are important for technologies like wearable devices and human-robot interfaces. But a hallmark of human perception is the ability to sense multiple stimuli at once, and this is something that robotics has struggled to achieve. Now, Jamie Paik and colleagues in the Reconfigurable Robotics Lab (RRL) in EPFL’s School of Engineering have developed a sensor that can perceive combinations of bending, stretching, compression, and temperature changes, all using a robust system that boils down ...

new study from Simon Fraser University researchers examines the Canadian military’s efforts to reduce the impacts of underwater noise pollution on species during training exercises in the Pacific Ocean but caveat that more can still be done. The paper, published today in Marine Policy, takes aim at a report commissioned by the Canadian Department of National Defence (DND) to reduce the effects of noise pollution from military small-arms munitions training within “Whiskey Hotel”, a 330-square-kilometre ...

Coverage of Bruce Willis’ frontotemporal degeneration shows media misconstrues the disease

2023-12-01

A new paper in Innovation in Aging, published by Oxford University Press, shows that a great deal of media coverage of the actor Bruce Willis’ condition, frontotemporal degeneration, was inaccurate, revealing the public’s limited knowledge of the disease. In 2022, Willis’ family released a statement saying that he had been diagnosed with aphasia, an acquired language impairment, and would retire from acting. Ten months later, the family issued another statement indicating doctors had diagnosed Willis with a more specific condition, frontotemporal degeneration. ...

Potential pitfalls when using the Cre-LoxP system in cancer research
