Robert E. Criss specializes in hydrogeology, the geology of water and systems of water. Much of his work has an environmental slant. His research spans many disciplines and has appeared in 50 different scientific journals, several government series and several books. He has conducted extensive field and geochemical work in many geologic environments in North America and has taught classes in geochemistry, hydrology, geochronology, speleology, field geology and related topics.
Criss frequently applies his knowledge of Missouri hydrogeology to local environmental problems. He has testified at many public hearings on flooding, floodplain development, landfill problems and groundwater contamination. His op-eds on these and other issues have appeared in several newspapers.
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.
As floodwaters surge along major rivers in the midwestern United States, a new study from Washington University in St. Louis suggests federal agencies are underestimating historic 100-year flood levels on these rivers by as much as five feet, a miscalculation that has serious implications for future flood risks, flood insurance, and business development in an expanding floodplain.
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 prevailing model for planetary accretion assumes that the Solar System’s planets formed in an extremely hot, two-dimensional disk of gas and dust, post-dating the Sun. In the March issue of Planetary and Space Science, two scientists at Washington University in St. Louis propose a radically different model, in which collapse takes place in a cold, three-dimensional dust cloud.
Washington University in St. Louis hydrogeologist Robert Criss, PhD, wasn’t particularly surprised by the spring floods on the Mississippi this year. Floods are becoming more frequent and more severe, he says. “We are increasingly constraining the river by building wing dikes and higher levees and then upping the ante by building in the river’s natural flood plains” Criss says. “There are far better ways to deal with this problem than have municipalities compete with one another to build the highest levee and fight over who has the right to be protected in times of distress.”
St. Louis floodplains are in danger of contamination from radioactive wastes dumped years ago at a landfill in North St. Louis County, according to Robert Criss, Ph.D. professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis.
CrissIt’s a 500-pound gorilla that Robert Criss, Ph.D., professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, sees standing on the speaker’s dais at political rallies, debates and campaigns. Its name is population growth. And sometime during President-elect Barack Obama’s first several months in office, he will have to factor it into future environmental policy, says Criss.”Population growth is driving all of our resource problems, including water and energy. The three are intertwined,” Criss says. “The United States has over 305 million people of the 6.7 billion on the planet. We are dividing a finite resource pie among a growing number of people on Earth. We cannot expect to sustain exponential population growth matched by increased per capita use of water and energy. It’s troubling. But politicians and religious leaders totally ignore the topic.”
