River delta

A radical plan to save the delta

An international cohort of designers, engineers, hydrologists, planners and other professionals — along with a handful of Washington University faculty, students and young alumni — have won a global competition charged with developing a 100-year plan for stabilizing the Mississippi River delta. A delta, says the Sam Fox School’s John Hoal, that’s on life support.

Record Missouri flood manmade calamity

Why was the New Year’s flood in Missouri so bad? Most news reports blamed it on the heavy rain, but Robert Criss, PhD, professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis says analysis of the flood data shows much of the damage was due to recent modifications to the river.

Archaic Native Americans built massive Louisiana mound in less than 90 days, research confirms​

A massive earthen mound constructed about 3,200 years ago by Native Americans in northeastern Louisiana was built in less than 90 days, and perhaps as quickly as 30 days, according to new research in the journal Geoarchaeology. The site was recently nominated for a place on the UNESCO list of Word Heritage sites.

Hydrogeologist questions reservoir releases and blasting rock to deepen the Mississippi for barge traffic

Coverage of the recent shipping crisis on the Mississippi River assumes that the appropriate response to a problem like low water levels is to find an engineering solution. Washington University in St. Louis hydrogeologist Robert E. Criss disagrees. He feels the river has been over-engineered and that many of the engineering “solutions” are not economic if all of their costs, including those to the taxpayer and to the environment, are taken into account.

The sustainable rivers program will be held April 22 from 10:30 a.m. to 5 p.m. and will feature Washington University faculty Charles Buescher, professor of environmental engineering, Robert Criss, Ph.D., professor of earth and planetary sciences in Arts & Sciences and William Lowry, Ph.D., professor of political science in Arts & Sciences. The colloquium will provide a background history of the rivers in our region and their various uses in transportation, agriculture, power production, recreation and public water supply.
