Another Dangerous Fire Season Is Looming In The Western U.S., And The Drought-Stricken Region Is Headed For A Water Crisis, Mojtaba Sadegh, Amir Aghakouchak, John Abatzoglou

Civil Engineering Faculty Publications and Presentations

Just about every indicator of drought is flashing red across the western U.S. after a dry winter and warm early spring. The snowpack is at less than half of normal in much of the region. Reservoirs are being drawn down, river levels are dropping and soils are drying out.

It’s only May, and states are already considering water use restrictions to make the supply last longer. California’s governor declared a drought emergency in 41 of 58 counties. In Utah, irrigation water providers are increasing fines for overuse. Some Idaho ranchers are talking about selling off livestock because rivers and reservoirs …

The Year The West Was Burning: How The 2020 Wildfire Season Got So Extreme, Mojtaba Sadegh, Ata Akbari Asanjan, Mohammad Reza Alizadeh

Civil Engineering Faculty Publications and Presentations

More than 4 million acres of California went up in flames in 2020 – about 4% of the state’s land area and more than double its previous wildfire record. Five of the state’s six largest fires on record were burning this year.

In Colorado, the Pine Gulch fire broke the record for that state’s largest wildfire, only to be surpassed by two larger blazes, the Cameron Peak and East Troublesome fires.

Oregon saw one of the most destructive fire seasons in its recorded history, with more than 4,000 homes destroyed.

What caused the 2020 fire season to become so extreme?

Thermoelectric Half-Heuslers: Synthesis, Processing, And Performance, Joseph Robert Croteau

Boise State University Theses and Dissertations

Thermoelectric half-Heusler compounds have potential to convert the heat wasted from industrial and transportation processes to useful electricity. Among the highest performing half-Heusler compounds are nano-structured bulk materials which have been arc-melted, pulverized into a nano-powder, and sintered by DC-hot press. High performing n- and p-type half-Heusler compounds with nominal composition of Hf_0.25Zr_0.75NiSn_0.99Sb_0.01 and Nb_0.75Ti_0.25FeSb, respectively, have been provided to us in both dense and powder form by our collaborators at the University of Houston. We consolidate these powders by SPS, refine these powders to improve both particle size …

Making The Human Dimensions Of Sustainable Community Development Visible To Engineers, Juan Lucena, Jen Schneider, Jon A. Leydens

Jen Schneider

Recently, engineers – particularly those working on sustainability-related initiatives – have increasingly turned their efforts towards under-served communities. This paper summarises the findings in Engineering and Sustainable Community Development (Juan Lucena et al., 2010) aimed at a diversity of these efforts which are grouped here under the term ‘engineering to help’. These initiatives often exist under names such as community service, humanitarian engineering, and engineers without borders or activities such as the Institution of Civil Engineers' co-sponsored workshop ‘Helping local communities to help themselves’. Although there has been a blossoming of engineering-to-help-related programmes around the world, there is a …

Putting Partnership First: A Dialogue Model For Science And Risk Communication, Jen Schneider, Roel Snieder

Jen Schneider

In April 2010, the New York Times reported that Vattenfall AB, an energy company owned by the Swedish government, had built one of the first coal-fired power plants designed to capture ~90% of the CO₂ it produced, with plans to sequester that CO₂ underground in geologic repositories near its plant in Brandenburg, Germany (Voosen, 2010). By most measures, if the plant's operations were proven to be successful, it could have served as a model for other carbon capture and sequestration plants worldwide.

Engineers, Development, And Engineering Education: From National To Sustainable Community Development, J. Lucena, J. Schneider

Jen Schneider

In October 2007, Norman Borlaug wrote in Science magazine that ‘more than 200 science journals throughout the world will simultaneously publish papers on global poverty and human development – a collaborative effort to increase awareness, interest, and research about these important issues of our time’. Borlaug, Nobel Peace Prize laureate and father of the green revolution, was demonstrating that the scientific community is at last taking questions seriously of sustainability and development. Borlaug's own contentious role in the history of ‘development,’ however, points to the complexity of the term and the contested role scientists and engineers have played in that …
