Grazie professore Zolezzi!


Steve, Guido Zolezzi and Christina talk around the Em3 in the Morris
Library rotunda on SIU campus.
Last week we helped SIU-Carbondale’s NSF-funded IGERT program welcome Guido Zolezzi for a special lecture.  Dr. Zolezzi is a professor in Civil and Environmental Engineering at the University of Trento in Italy.

Dr. Zolezzi heads the European SMART (Science for Management of Rivers and their Tidal Systems) program, an interdisciplinary doctoral partnership much like SIUC’s IGERT program.

He gave a fascinating talk on the downstream effects of dam releases in European rivers.  His work has been recently published in various issues of  Ecohydrology and River Research and Applications and includes study of thermal effects of power plants, thermal peaking on inverts, and upstream aggradation related to channel expansion.

I thought I understood urban rivers, but Dr. Zolezzi's research on the Kugart River, in the Kyrgyz Republic, a great story of how Cold-War Soviet engineers struggled with design of a high-bedload urban channel, changed my view of urban channel hydraulics and sediment transport.  Map link here.

A fantastic speaker in English and a charming man, Dr. Zolezzi is  currently on sabbatical at Texas A & M University. 

We set up an Emriver Em3 in SIUC’s Morris Library for a pre-lecture reception; we had a wonderful talk with Dr. Zolezzi there.

Thanks to our colleagues at SIUC for organizing this meeting, especially Nicholas Pinter.

Here are recent publications.  I could not find a comprehensive list in English, these are from Dr. Zolezzi's CV in Italian(PDF):
