California Flood Risks Are a "Disaster Waiting to Happen," Say UM Engineers

Clark School Engineers Report on Country's Aging Water-Related Infrastructure; Restoring Ecosystems May Hold Key to Flood Prevention

By Missy Corley

COLLEGE PARK, Md.-- While flooding in California's Central Valley is "the next big disaster waiting to happen," water-related infrastructure issues confront almost every community across the country, according to engineers at the University of Maryland's Clark School of Engineering in separate reports to California officials and in the journal Science.

An independent review panel chaired by Clark School Research Professor of Civil Engineering Gerald E. Galloway said the area between the Sacramento and San Joaquin river floodplains faces significant risk of floods that could lead to extensive loss of life and billions of dollars in damages. The panel's report, "A California Challenge: Flooding in the Central Valley," was commissioned by California's Department of Water Resources.

The panel pointed out that many of the area's levees, constructed over the past 150 years to protect communities and property in the Central Valley, were poorly built or placed on inadequate foundations. Climate change may increase the likelihood of floods and their resulting destruction. The panel recommends that state and local officials take swift action to reduce the risk to people and the environment.

The comprehensive flood-risk abatement strategy the panel recommends focuses on land-use planning and integration with other basin water management activities.

"The challenges that California faces are widespread across the nation," Galloway said. "The recent failure of a levee in a Nevada irrigation canal points out growing infrastructure problems."

Another civil engineering researcher from the Clark School, Lewis "Ed" Link, also served on the California panel.

"I believe the State of California is taking a very enlightened approach to difficult issues," Link said. "Supporting this study is a good example, as is their examination of risk for the entire Central Valley. They are looking strategically at measures that can create long-term solutions, a model for others to follow."

Aging Infrastructure and Ecosystem Restoration

"As we move forward with infrastructure enhancement, we must consider how, in the process of carrying out these activities, we can restore and enhance the natural and beneficial functions of the floodplain, which can at the same time reduce flood losses," Galloway said.

Link and Galloway were prominent figures in the review of the levee system around New Orleans after Hurricane Katrina devastated the area. Link served as director of the federal government's Interagency Performance Evaluation Task Force, which evaluated the hurricane protection system around New Orleans. Galloway is a former brigadier general with the Army Corps of Engineers and has been part of the State of Louisiana review team looking at long-term plans for restoration of the Gulf Coast.
