Flash back to the 2008 flood that caused so much damage to the University of Iowa, here we are almost 11 years later and it looks like global warming is forcing us to get prepared for whatever may come our way.
Back in 1905, the university had been warned by landscape architects, not to build so close to the water, as it could cause problems, but the university was struggling to find land. Due to the flooding, over 20 building were affected on the university of Iowa campus. The flood made costly calls for change, causing the university to spend millions for the damages.
The flood of 2008 may not be the worst we have seen just yet, around the United States, floods, wild fires, hurricanes and other natural disasters have gradually become worse and caused mass devastation in different areas.
University of Iowa’s Don Guckert has been keeping the university safe and travelling the country to inform or educate other institutions about the disasters that occurred at the University of Iowa and how to be prepare for a natural disaster. He has gotten busier over the last five years as global warming has become a bigger issue as time passes.
We all know that its not easy to avoid but preparing for it can help save countless lives and heavy costs. University of Iowa is still rebuilding from the flooding that occurred.
Recent Iowa State University data shows that 100-year flood plain maps actually map 25-year flood plains. The data also shows that an increasing frequency of large rainfall events throughout Iowa. In Cedar Rapids, the number of heavy rainfall events has increased by 57 percent over the last 100 years.
Kamyar Enshayan, director of the University of Northern Iowa Center for Energy and Environmental Education says that part of the reason for these increases in flooding is coming from changes in land use.
“Over the last 100 years, we have significantly altered the hydrology of our state. The part that we can do something about that would have fairly immediate results is land use change, meaning changing the way our cropping system works, and reestablishing some of the elements we’ve lost like wetlands and forests.”
Currently, the vast majority of Iowa’s agricultural land has, for a long time, been under cultivation in a two-year, corn-soybean rotation. Long-term studies at Iowa State University have demonstrated that moving to a three or four-year crop rotation would lead to a significantly different system that could naturally reduce flooding.
Researchers in Iowa are now analyzing the impact of upstream flood mitigation efforts — as well as determining the costs of potential efforts.
For example, the cost of funding watershed management projects, to help mitigate flood in the state is estimated to be around $5 billion, which is a bargain when put in the context of the cost of flood damage recovery. The damage from the 2008 flood alone was estimated at $10 billion across the state.
Flood mitigation efforts in the state thus far have centered around building levees, flood walls, and protecting utilities, but Iowa researchers have found that upstream structures like wetlands and detention pounds are an effective means of flood prevention. Sen. Rob Hogg of Cedar Rapids said that some lawmakers have acknowledged the need to ramp up these strategies, but the conversation is often buried by health care and education budget arguments. Hogg said, “If you can’t reach agreement over funding the basics, it’s really hard to get to the next level, to discuss funding water management.”
The increasing frequency of extreme rainfall may demand that flood mitigation take center stage at the capital. “We were hard-pressed to get 4-inch rainfalls 100 years ago, and now it’s very common,” said Jerry Schnoor, co-director at the University of Iowa’s Center for Global and Regional Environmental Research. Eugene Takle, director of the climate science program at Iowa State University, agreed, “In the Cedar River basin, we found the 100-year flood a century ago is now very likely to be a 25-year flood.” The Cedar basin’s record flood in 2008 had a $5 billion price tag.
Takle and other experts say these changes are primarily due to climate change. Rising greenhouse gases in the atmosphere allow it to hold more water vapor. “When you have more water vapor, you can expect more rain events,” he said. Takle’s data support this claim: atmospheric water vapor has increased by 31 percent in the winter months since 1970 and by 14 percent in the spring; average annual rainfall in Iowa has risen by 33 percent since 1970. Takle said, “This is consistent with what the climate models said would happen. The Midwest has experienced a big increase in extreme events.” According to NOAA National Centers for Environmental Information, Iowa has had 26 flood disasters with damages adding up to more than $1 billion since 1980.
Larry Weber, director at the University of IIHR – Hydroscience & Engineering, parent organization of the Iowa Flood Center, said that the loss of prairie potholes and wetlands, which can soak up heavy rainfalls, has contributed to these flooding events. He said, “We’ve taken away a lot of those natural storage areas.”
Iowa lawmakers passed a sales-tax funding plan in 2012 to provide $1.4 billion in flood prevention structures, but more funding is needed. Eight-nine towns and cities have identified $35 million in flood prevention structures that do not have funding. Some Iowa lawmakers are working to increase the sales tax by three-eighths of 1 cent in order to fund the Natural Resources and Outdoor Recreation Trust Fund, which would provide $180 million each year to restore wetlands, protect wildlife habitat, reduce runoff and improve trails, and more.
One and a half million dollars in federal supplemental aid money allocated to the Iowa Flood Center’s Iowa Watersheds Project after the 2008 flood has reduced flooding downstream by 15-20 percent in the Otter, Beaver and South Chequest watersheds. The center received $98 million in federal grant money this year for similar flood mitigation projects in 25 additional watersheds. Weber said, “We’re making great strides in the places where we work, we just need to be working in more places — whether it’s through our projects, or the work of other state and federal agencies, private landowners, and nonprofit groups.”
The proposed removal of the Quaker Mill dam near Manchester and the repair of a breached levee should be highly favorable to all parties involved, according to backers of the project. They predict that it will benefit the environment, recreational users, local government, and even the dam’s owners. Continue reading →
FEMA claims that the building was not damaged enough to warrant a full replacement, but UI officials argued that because no insurance company will cover the school’s art collection at the existing location, a new facility is necessary.
“We are very disappointed that the state and university’s appeal for the replacement for UI art museum has been denied by FEMA,” said UI spokesman Tom Moore in an email. “University officials are reviewing our next steps in coordination with the state.”
