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.

Iowa’s flood season started off with an splash this week. The state saw road closures, city evacuations and one even one collapsed bridge. In wake of major damage from east to west, Gov. Kim Reynolds issued a statewide disaster proclamation Thursday.

The official proclamation activates the State Emergency Operations Center to coordinate disaster response using state resources. It also activates the Iowa Individual Assistance Grant Program for qualifying residents; those with household incomes up to twice the federal poverty level have 45 days after the proclamation to apply for up to $5,000 in flood damage repairs.

The proclamation also activated the Disaster Case Management Program in 21 counties. Case managers help those seriously affected by disasters overcome adversity by helping them create a disaster recovery plan and offering guidance, advice and referrals.

Better safe than sorry

The flood season has only just begun and is expected to be brutal this year. Flood insurance takes 30 days from purchase to become active, but flood risk is an all-year hazard, especially in Iowa. It is not too late to protect your household from future floods.

Do you live in a flood plain? Find out here and remember that over 20 percent of flood insurance claims come from properties outside the supposed “high-risk” zone. The average claim is about $30,000: six times more than the maximum granted by the Iowa Individual Assistance Grant Program and with no income requirement.

Be aware of present flood risk as well. Watches are ongoing in much of the state. Be sure to…

  • Avoid driving across even shallowly flooded roads.
  • Keep at least a day’s supply of shelf-stable food and water in your home, especially if you live in a floodplain.
  • Check here for up-to-date road closures.
  • Visit the Iowa Flood Information System for flood alerts and more.

While Iowans rejoiced over spring-like weather this week after a long, brutal winter, flooding caused by rapid snowmelt and heavy rains has threatened communities across the state.

Iowa weather services have been reporting higher-than-average risks for major flooding this spring since late February, and many outlooks have only increased within the last week, according to the Des Moines Register. The risk is most pronounced along the Mississippi River, where a Quad Cities survey found the risk of flooding through May to be 95 percent last week. The National Weather Service says flooding in the Quad Cities could break records.

The National Weather Service issued a flood watch Wednesday morning that will last until at least this evening across most of the state. In some areas the watch will extend into next week. Below is information on flooding and alerts throughout the state as of this morning.

East

  • Major flood stage was reached in Waterloo, Maquoketa and DeWitt as of Thursday morning. Moderate flood stage was reached in many areas Wednesday, including Kalona, Atkins and Augusta (IFIS).
  • Yesterday, Cedar Rapids expected a “moderate flood stage” when the Cedar River crests early next week. Officials said this should be fairly insignificant for residents. The city had already reached moderate flood stage as of Wednesday night (Gazette/IFIS).
  • An ice jam raised alarm in Ottumwa Wednesday morning, though it only caused minor agricultural flooding (Des Moines Register).

Central

  • Squaw Creek in Ames reached major flood stage Wednesday afternoon. As of Thursday morning, all areas were at or below moderate levels (IFIS).
  • An ice jam collapsed a bridge in Johnston Wednesday evening. The trail leading to the bridge had been closed prior to the collapse (Des Moines Register).
  • Des Moines Public Works closed parts of George Flagg Parkway and Fleur Avenue. These could remain closed for days (WHOtv).
  • An ice jam in the Raccoon River flooded rural communities in Dallas County (Des Moines Register).

West

  • Western Iowa was hit worst of all. As of Thursday morning, eight communities from north to south were at major flood stage (IFIS).
  • The Boyer River in Hogan and the West Nishnabotna River near Avoca reached major flood stage Wednesday afternoon. A Red Cross station was set up in Avoca for those displaced from homes (kwbe/IFIS).
  • Underwood in Pottawattamie County lost function of its sewer lift system Wednesday. Residents were asked to stop flushing toilets temporarily (kwbe).
  • Harrison County Emergency Management ordered a partial evacuation of Missouri Valley Wednesday night. As of 9:20pm, 2,600 people were underwater (Des Moines Register).
  • Several roads have been closed as well. Check 511ia.org for current closures. 

Take care around even shallowly flooded areas, especially when driving. Remember that while newly-purchased flood insurance takes 30 days to go into effect (and will therefore not help you this week), Iowa’s flood season has only just begun.

Climate Assessment predicts water stress on multiple levels for U.S.

We already know climate change is having major impacts on rainfall. The 2018 Iowa Climate Statement said the strongest rainfall events of the year may double in intensity by 2025.  Climate change will alter the hydrologic cycle in other ways as well, majorly changing society’s relationship with water.

The Fourth National Climate Assessment, controversially released Black Friday, details the forecasted changes to water supplies in the U.S.. It compiles the findings of over 300 experts and has been reviewed by 13 federal agencies, in an effort to inform top decision-makers and common citizens.

More intense rainfall will be met with more intense drought and reduced snowpack, which is bad news for communities that rely on glacial melt for their water supply. These changes are exacerbating water availability issues caused primarily by overuse of groundwater aquifers in much of the U.S..

As higher temperatures create even higher demand for water for drinking and irrigation, this problem will only get worse and worse, which will have major implications for both the food supply and the industrial sector.

The altered hydrologic cycle will impact the quality of our limited quantity of water as well. Rising water temperatures will impact the health of ecosystems, and changes  runoff patterns of pollutants into water will impact human health and pose challenges for water treatment facilities. Sea level rise could also threaten coastal drinking water supplies with the potential intrusion of saltwater flooding.

The report says the biggest water issues for the Midwest are adapting stormwater management systems and managing harmful algae blooms. Iowa is already familiar with floods produced by intense rainfall.  Algae blooms, fueled by nutrient-runoff from farm fields, will be further increased by rising temperatures.

Other water-related challenges detailed in the assessment include the deterioration of water infrastructure and managing water more strategically in the future.

 

Hurricane Harvey worsened by Houston skyline

Houston can partially blame the unprecedented flooding it experienced during Hurricane Harvey last year on its skyline. A new study co-authored by Gabriele Villarini, associate professor of civil and environmental engineering and director of IIHR-Hydroscience and Engineering at the University of Iowa, found that Houston’s topography exacerbated Harvey’s rainfall.

Researchers obtained data on rainfall and water discharge in Houston during the storm from various national agencies, and compared it to a computer model that simulated the same storm with a twist. In the model, the city of Houston was replaced with undeveloped farm fields to calculate the built environment’s effect on the storm’s behavior.

The analysis concluded that urban development in the Houston area increased the likelihood of intense fooding 21 times during that particular storm. In other words, if Houston were really an expanse of farmland instead of a city, less rain would have fallen.

“The buildings stop the air from being able to move forward, away from the ocean,” co-author Gabriel Vecchi from Princeton told NPR. “They sort of stop the air in that general area, and the air has nowhere to go but around the buildings, or up.”

Vecchi said when tall buildings push air farther upwards, the amount of atmospheric water vapor that condenses into rain increases. Houston’s skyline not only stalled the storm, but squeezed more rain out of it.

 

 

 

Iowa expects to get drenched

Julia Poska | October 5th, 2018

After its third-wettest September on record, Iowa can expect a rainy October, too. The DesMoines Register reported that 4 to 5 inches of rain are forecasted to fall over most of the state in next few days. For some localities, it’s already started.

Southwest Iowa may be hit the hardest. Forecasts there predict 6 or more inches of rain.

The rain is expected to fall almost endlessly at least into early next week. National Weather Service meteoroligst Brooke Hagenhoff told the Register that the widespread nature of the forecast will likely increase the rainfall’s impacts on rivers and low-lying areas.

Some parts of the state are already saturated. Despite a fairly dry start to the month, flood alerts have been active for parts of the Des Moines, Cedar and Iowa Rivers throughout this week thanks to late-September rains in northern Iowa. The Iowa Flood Information System gauged a major flood stage for the Wapsipinicon River at DeWitt as of Wednesday afternoon.

 

How to curb Iowa flooding according to an agricultural engineer

Sandbags like these are not an adequate solution to Iowa’s flood problem, Kamyar Enshayan warned (flickr).

Julia Poska| September 21, 2018

In an effort to call Iowa to action, Kamyar Enshayan, director of the University of Northern Iowa’s Center for Energy and Environmental Education, called on his expertise as an environmentalist and agricultural engineer for a Des Moines Register OpEd earlier this week.

Enshayan warned Iowans that flooding will only get worse as the climate changes and gave those upstream three pieces of advice to protect their downstream statesmen.

First, he said we should hand floodplains back to nature. He called for an end to construction and development along riverbanks, arguing that the ecosystem services floodplains provide are more valuable than riverside property.

Natural floodplains improve water quality, provide great wildlife habitat, offer natural flood protection and reduce flood disaster and recovery costs according to the Nature Conservancy. 

Second, we need to make Iowa more “spongy” with sustainable cropping and biodiversity solutions. Enshayan suggested increasing crop diversity in longer rotations to promote healthy soil. Deep-rooted native prairie plants and natural wetland ecosystems will also help contain water.

Finally, he said we must get to the root of the problem and reduce carbon emissions to mitigate climate change. He pointed to methane-emitting landfills and Iowa’s continued dependence on coal as areas for potential improvement.

Enshayan addressed policy makers at the end of the piece, saying they should listen to scientists and engineers like himself to proactively protect people and resources.

“Sand bagging is not enough, not a lasting solution, and does not address upstream problems,” he said.  “Let’s work on lasting solutions.”
