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.
