    and Cedar Rapids The tool allows users to view flood levels at various river stages Elkader Mayor Robert Garms says that the IFC s efforts to better prepare Iowans for flooding are very valuable It helps communities have a better understanding of what can happen he says Left Flood inundation map of Elkader Iowa illustrating 2008 flood levels Right Flood inundation map showing 2014 flood levels in Elkader Jennifer Cowsert Elkader City administrator says people are very interested in viewing the IFIS website she even had businesses cards printed with the web address to hand out I can show them a map and how it will impact their property Cowsert says She believes that the IFC carries more weight in the minds of individuals when family homes and businesses are on the line and that the IFIS maps have been spot on Cowsert says the maps were particularly useful during flooding in June 2014 We moved campers out of the city campground moved items out of two public buildings started making sandbags and then watched and waited Cowsert says She admits that the real cost of the damage debris removal a damaged flood wall and levee and an exposed sewer line couldn t be avoided but that if the river had gone up more the sandbagging could have helped prevent losses to businesses Turkey River Watershed Management Authority Cowsert is very familiar with the IFC She also represents the city on the Turkey River Watershed Management Authority TRWMA which has partnered with the IFC s Iowa Watersheds Project funded by the U S Department of Housing and Urban Development HUD to model flood reduction strategies The IFC s involvement in the Turkey River watershed and in the TRWMA has been very positive Cowsert says The IFC helps the authority move forward and stay focused on its mission She adds that the IFC helps elevate the TRWMA to a state level It isn t just our little part of northeast Iowa and our flooding concerns anymore It reminds everyone that our part of the state affects everyone else and vice versa and that flooding in Iowa is a concern for the entire state not just the communities that feel the brunt of the flood waters Roger Thomas Elkader s Main Street Coordinator and Economic Development Director as well as local state representative says he believes IFC involvement will continue to help in technical ways that may open up funding opportunities for members of the TRWMA I think the Iowa Flood Center brings attention to flooding concerns in Elkader by bringing attention to the whole watershed as well as the Turkey River itself Iowa s Flood Partners Jeff Zogg knows that flooding which has accounted for almost three fourths of all presidential disaster declarations in Iowa is a big deal for Iowans And for Zogg it s one of the most important parts of his job As senior hydrologist at the National Weather Service NWS office in Des Moines Zogg is responsible

  • Floodplain Mapping: Kalona, Iowa – IIHR – Hydroscience & Engineering – University of Iowa
    results of IFC s own 2D modeling of the area The map looked quite a bit different than the FEMA original Using LiDAR laser radar data to develop a digital elevation model the IFC team modeled the geometry of the river and creek beds as well as the surrounding area Using the new map Kalona s flood insurance tab would be cut almost in half This is a more advanced engineering approach Weber explains And it s more appropriate The new maps will undergo another round of revisions when the IFC team applies a major precipitation event to the model This added layer of complexity will better show where the true risk is Weber explains We want to be able to provide the best possible map The services of the Iowa Flood Center have been crucial to Kalona as the town finds its way through a complicated and costly situation says City Administrator Ryan Schlabaugh The goal is to have the most accurate map possible he says and the Iowa Flood Center is helping us do that Weber says that by working through this process with Kalona the IFC has learned important lessons that can be applied elsewhere IFC researchers are in the midst of a four year Iowa Floodplain Mapping Project To complement the Kalona mapping project five undergraduate engineering students are also working on a floodwater management plan for Kalona suggesting flood mitigation projects such as rainwater storage structures and buffer strips Although the process has by no means been a simple one for Kalona the community is in effect leading the way through complicated waters Tags FEMA Iowa Flood Center Iowa flooding Iowa Floodplain Mapping project Kalona Iowa Larry Weber LiDAR Nate Young Last modified on June 25th 2015 Posted on February 28th 2012 Home About Greetings from the Director Fact Page IIHR at a Glance Where is IIHR Communications History IIHR s Historical Studies History Resources Hans Albert Einstein His Life as a Pioneering Engineer Sustainability at IIHR Evolving with the Times Intellectual Connections Worldwide IIHR Alumni Worldwide Archives Films by Hunter Rouse Employment Contact IIHR Webcam Education Graduate Program Admission Assistantships and Fellowships Graduate Student Opportunities Undergraduate Opportunities International Perspectives Service Projects Habitat for Humanity s Women Build Project Fluids Lab Meet Our Faculty and Staff Brandon Barquist Talking Shop Pablo Carrica Enjoying the Challenge George Constantinescu Rivers Run in the Family Carrie Davis Playing in the Mud Teresa Gaffey Transformations Anton Kruger How Stuff Works Troy Lyons Bridging the Gap Ricardo Mantilla Going with the Flow Jacob Odgaard Making an Impact Michelle Scherer Solving the Puzzle Fred Stern Revolutionizing Ship Hydrodynamics Stephanie Surine She s a Rocker Eric Tate Studying the Human Costs of Flooding H S Udaykumar The Reluctant Engineer Gabriele Villarini Working the Numbers Mark Wilson What s Not to Like Meet Our Students Tibebu Ayalew Accidental Engineer Ali Reza Firoozfar The Experimentalist Ruben Llamas Success among Friends Beda Luitel Finding a Way Kara Prior For the Love of Discovery Harvest Schroeder

  • Iowa Watersheds Projects – IIHR – Hydroscience & Engineering – University of Iowa
    end of the day we wouldn t be any smarter Weber says Earlier this year the team assembled a watershed selection committee that represented many viewpoints and stakeholders from across the state The committee analyzed proposals from nine watersheds and selected four to participate in the project each representing a different geographical and topographical area of the state as well as a different land use pattern The project is broken into two phases the first of which is the hydrologic assessment What exactly is a hydrologic assessment Steussy defines it as modeling to help us understand the movement of water in the watershed When rain falls where does it end up she says The hydrologic assessment will use computational modeling to identify areas in the watershed where the constructed projects will have the most impact on reducing downstream flood damage Graduate students Nick Thomas Matt Wunsch Chad Drake and Will Klinger use physically based computational models to represent the terrain land use geography etc in each of the four watersheds They re also collecting data and further developing the model It s rewarding work says Drake a first year graduate student He is researching the Upper Cedar River Watershed I ve enjoyed studying the impact water can have on people Drake says I also like the close proximity of the project to its practical applications In the meantime Weber and the rest of the team are holding regular meetings with constituents in the watersheds It s impossible to overestimate the impact of this human aspect Weber says Landowner participation and watershed engagement are the most important element A 50 Year Vision After 18 months of modeling and meetings watershed representatives will choose a few very small areas of the watershed in which to build the improvements with advice from the IFC researchers That s Phase II expected to begin in 2014 The improvements could include farm ponds wetlands floodplain easements and more The projects will be kept small so researchers can clearly assess and analyze their impact But even areas that don t directly benefit from the construction of a project will have an advantage moving forward Weber says They will be left with valuable documents and data developed through the hydrologic assessment allowing them to better compete for funds in the future The payoff for researchers and Iowans will come at the end of the project when they can begin to understand what works best in each watershed and which strategies can be scaled up for implementation throughout the state Weber hopes that the results of the Iowa Watersheds Project can help provide a long term plan for improving the state s flood resiliency I like to think about vision he explains In this case a 50 year vision for watershed enhancement Tags Chad Drake HUD IIHR Iowa Flood Center Iowa flooding Iowa Legislature Iowa National Guard Iowa Watersheds Project Larry Weber Marian Muste Nick Thomas Sara Steussy Water Resources Coordinating Council Last modified on June 25th 2015 Posted

  • Partnerships for Iowa Watersheds – IIHR – Hydroscience & Engineering – University of Iowa
    incredibly challenging says Jennifer Filipiak of The Nature Conservancy However we are all motivated by a singular vision a sustainable Cedar Iowa River watershed Jason Smith of the U S Army Corps of Engineers agrees and adds that including many points of view is important I think it keeps the approach balanced he says Public participation is also an important part of the process I believe the biggest opportunity for change lies in how the project seeks to engage the public in watershed management and planning says Mary Beth Stevenson a representative of the Iowa Department of Natural Resources who serves as Iowa Cedar Rivers Basin coordinator Intelligent Digital Watershed One of ICWICT s primary goals is to develop tools to help people make informed land use decisions that weigh the economic environmental and social aspects of their choices One such tool is the intelligent digital watershed developed to support integrated and sustainable water resources management and a better understanding of human natural system interactions through the use of advanced computer and communication technology The best available hydrological sociological and economic data are used in this cyberinfrastructure based system for monitoring modeling and forecasting within a watershed The information is made available in a user friendly and easily accessible system Giving land managers the opportunity to visualize the broad impact of decisions made locally could be a powerful agent of change Stevenson explains Muste has been one of the drivers of the cyberinfrastructure efforts on campus since 2004 when he created a multidisciplinary research group in response to the National Science Foundation NSF cyberinfrastructure initiative Muste and his colleagues were awarded NSF grants in 2006 2008 and 2011 supporting cyberinfrastructure projects designed to understand and manage watersheds in an innovative way Filipiak believes ICWICT s work is critical Globally our freshwater resources are imperiled Humans need water in so many different ways for so many different reasons Water really is life The HELP initiative is a global network including more than 90 HELP basins in about 70 countries The Iowa HELP watershed is one of five in the United States and the first in the Midwest To learn more about the Iowa Cedar Watershed Interagency Coordination Team visit http iowacedarbasin org Tags Cedar River hydrology IIHR Iowa River Iowa watersheds Marian Muste UI research UNESCO HELP water quality Last modified on June 25th 2015 Posted on March 6th 2012 Home About Greetings from the Director Fact Page IIHR at a Glance Where is IIHR Communications History IIHR s Historical Studies History Resources Hans Albert Einstein His Life as a Pioneering Engineer Sustainability at IIHR Evolving with the Times Intellectual Connections Worldwide IIHR Alumni Worldwide Archives Films by Hunter Rouse Employment Contact IIHR Webcam Education Graduate Program Admission Assistantships and Fellowships Graduate Student Opportunities Undergraduate Opportunities International Perspectives Service Projects Habitat for Humanity s Women Build Project Fluids Lab Meet Our Faculty and Staff Brandon Barquist Talking Shop Pablo Carrica Enjoying the Challenge George Constantinescu Rivers Run in the Family Carrie
