56 We Are IIHR

Follow IIHR, the Iowa Flood Center, and the Iowa Geological Survey on social media. Director of Development and Communications Carmen Langel Editor/Writer Jacqueline Hartling Stolze Design Benson & Hepker Design Photographer Aneta Goska On the Cover With 100 years of research and stories to share, this issue of IIHR Currents is devoted almost entirely to a pictorial timeline of our history.

ow many times have you walked by the old millstones built into the west entryway to the Stanley Hydraulics Lab, perhaps without giving them a thought? For me, starting when I was a student and now as IIHR director and faculty member — well, it’s simply too many to count! Lately, though, I’ve begun to pause and ponder the millstones for a moment on my way out the door. For one thing, they are beautiful — a testament to the workmanship and industry of a generation that has passed. History is also much on our minds here at IIHR as we begin our centennial year, and it recently occurred to me that the millstones offer an apt metaphor for the solid foundation upon which IIHR is built. Or, with a nod to Sir Isaac Newton, we stand upon the shoulders of giants. IIHR’s founding director, Floyd Nagler, had a passion for rivers, waterpower, millstones, and turbines. Nagler wrote fondly of the “awe and delight” he felt when visiting old water mills. In the 1920s and early ’30s, Nagler directed his staff to keep their eyes open for abandoned mills as they conducted fieldwork around the


Standing on the Shoulders of Giants from the director state. An IIHR survey team found the entryway millstones north of Iowa City in the mud of Mill Creek in Big Grove Township (Mill Creek would later be dammed to form Lake Macbride). Legend has it that Nagler carried the massive stones to his car singlehandedly. While I can’t vouch for this, I do believe that Nagler, with his remarkable energy, focus, and vision, established the hydraulics lab on sturdy bedrock that continues to serve us well, even as we evolve with the world around us. Thanks to Nagler and all the directors, researchers, students, and staff who came after him, IIHR has been able to effectively navigate a changing landscape for a full century. Part of IIHR’s success has to do with the fact that we have remained true to our central pursuit of excellence in fluids-related research and education. But at the same time, the institute has been flexible and visionary enough to understand what is needed at a societal level and to respond, or even foresee, “the next big thing.” Of course, I give much of the credit for this vision and foresight to our “founding fathers” — Nagler and the remarkable directors who followed. They demonstrated an extraordinary ability to see and understand what society needed, often before anyone else did, and to position IIHR to meet the need. To cite just one example, Kennedy foresaw American cities’ need for large underground sanitary and stormwater storage systems to replace aging, inadequate sewers. Under his leadership, IIHR became (and continues to be) a world leader in the design and modeling of the dropshafts, tunnels, and storage chambers essential for modern combined sewer overflow systems.

Over the decades, people have looked to IIHR to address many fluids-related issues. As a world-renowned lab, we respond to these needs with integrity and with purpose, always staying true to Nagler’s vision, which has continued to develop to the present day. It’s not just the directors who have built IIHR — it’s also every person who has ever played a role here over the years. To carry the metaphor a bit further, we stand upon the bedrock of Nagler’s foundational vision; each of us who contributes bears a bit of the load, like a brick in the iconic physical structure we inhabit. We are fortunate to have inherited a magnificent legacy, one that we cherish, honor, and respect. But the world in which we operate continues to change, as it has for 100 years, and we remain well-positioned to address these changing needs, today and in the decades to come. I would like to invite all of you to join us in our centennial celebration in 2020. We have many exciting events planned, especially for our alumni and friends! Please take a look at the details on page 3 and make your plans to attend!

Once Upon a River from the editor

I

often think of myself as IIHR’s storyteller-in-chief, and I can’t think of a better job anywhere! For 10 years, it’s been my job and my pleasure to tell you the stories of IIHR in our annual magazine, IIHR Currents. Ten years is a milestone, but it’s a mere grain of sand compared to the full hourglass of IIHR’s 100-year history. By the way, if you haven’t already heard, IIHR is celebrating its centennial in 2020! We have lots of exciting activities planned and we hope you’ll attend. Please do join us in Iowa City this August to celebrate. But the centennial also presented us with a challenge: how best to cover 100 years of history in the limited space available in IIHR Currents? The solution we landed on was a timeline. We wanted to recreate something like an old-fashioned scrapbook — the kind that your mother or grandmother might have delighted in crafting with scissors and a pot of glue. Scrapbooks at their best are a crazy quilt of photos, artifacts, and impressions that combine to create a joyful, multi-layered experience. We hope you enjoy the results as much as we enjoyed making it! As Carmen Langel (director of development and communications) and I began pondering our communication plan for the centennial, we often thought of how fortunate IIHR is to have a professionally curated archive chronicling our history with documents, photographs, and artifacts. For this we must thank Connie Mutel, our recently retired senior science writer and founding archivist. Connie’s exacting standards of accuracy and the care she took with every detail have been a true gift. She also wrote the definitive history of IIHR from 1920 through 1998, Flowing through Time: A History of the Iowa Institute of Hydraulic Research. My copy of Flowing through Time is dog-eared and bristling with post-it notes. How many times have I referred to it over the last few months? I can’t even begin to guess. Connie’s work has made our jobs so much easier! I have been privileged to collaborate with Connie on the sorting, preservation, and cataloguing of IIHR’s photo archives. It was fascinating and the best possible preparation for this year of retelling IIHR’s history. I don’t claim to be an archivist such as Connie, but I do love history, and IIHR’s archives are stuffed full of stories waiting to be told. I’d like to thank our amazing photographer, Aneta Goska, who also took on the daunting task of scanning and organizing our archival photos. With the help of several students, Aneta provided us with an electronic library of images that we will use for years to come. We hope you enjoy this issue of IIHR Currents, and we look forward to seeing you in August! See you soon, Jackie Hartling Stolze Editor, IIHR Currents Lead Communications Specialist, IIHR P.S. We’re excited to share the news that IIHR Currents won a gold award in the Best Annual Report category of the Council for the Advancement and Support of Education’s “Pride of CASE V” awards program!

hat is it that makes IIHR—Hydroscience & Engineering so extraordinary? It’s a question we could likely debate for the next hundred years. One thing is clear, however—since its beginnings, IIHR has inspired people to do amazing work. Maybe there’s something in the water here that brings out the best in us. Once upon a time, perhaps, it was more common to feel this strong sense of identity, of cohesiveness, of belonging. Today it is a rarity, and something that we must defend and preserve. It all began with IIHR’s founding director, Floyd Nagler. He brought passion and energy to the new institute; he also treated the institute’s people like family. Later, each IIHR director put his own stamp on the institute. As leaders, they were unique and distinctive, and they inspired fierce loyalty and dedication in their colleagues and employees. People were proud to say they were part of the Iowa Institute of Hydraulic Research, just as we take pride in our association with IIHR today. Each of us — whether director, researcher, staff, student, or alumnus — feels that strong sense of identity and mission. IIHR continues to attract and retain top-notch people. We at IIHR also make it a point to honor our history, and to keep it in mind as we move forward. Nagler might be surprised by some the recent developments at IIHR, but he would no doubt be proud of its continued evolution. He would still recognize the same IIHR spirit that he knew in his day. Perhaps most important, we at IIHR understand that we are involved in something bigger than ourselves. Our work has important implications for the well-being of our state, our nation, and our world. It’s energizing to know that IIHR’s research literally makes the world a better place. This sense of context keeps us going when we’re tired, when we’re discouraged, and when we might want to relax and take an easier route. From top to bottom, IIHR’s people care about the institute and give it their best work and deepest commitment. IIHR’s retired senior science writer Cornelia F. Mutel said it well. “People here really love what they are doing. You can sense that energy when you step through the door.” Step through the door with us now for a walk through IIHR’s first century. We hope you enjoy this timeline of important events in the history of IIHR— Hydroscience & Engineering.

IIHR culvert research helps solve practical problems for highway improvement. IIHR’s fascination with Ralston Creek begins. Nagler initiates data collection in this small watershed, including flow in the channel and over the ground. This research continues through 1988, creating the longest set of in-depth groundwater data on a small watershed in existence. David Yarnell of the U.S. Department of Agriculture (USDA) sets up an office at the hydraulics lab. The USDA would fund a series of culvert studies at the institute in support of the U.S. highway system, which is in its infancy. Yarnell is the first of several agency representatives to rent office space at the lab, facilitating partnerships and providing muchneeded research funding.

Nagler, a man of great energy and can-do spirit, begins his quest to expand the Hydraulics Lab. The first of these expansions occurs in 1928 with the opening of a new 60-by-30-foot laboratory (below) with three stories and a basement. It features experimental equipment such as flumes, weighing tanks, measuring basins, a pump room, and a circulating water system. The top floor is dedicated to classroom and office space.

Through the 1940s, IIHR also helps educate University of Iowa medical students on the dangers of waste back-siphoning.

1939 Hunter Rouse arrives at IIHR. Educated at MIT and in Europe, he comes to Iowa from a position at CalTech. He has already written his first hydraulics textbook, Fluid Mechanics for Hydraulic Engineers. IIHR holds the first of many professional Hydraulics Conferences (below). Held every three years until 1958, these conferences provide an opportunity for networking and information exchange among leading experts in the field.

IIHR Goes World War II brings new research initiatives and funding sources to the hydraulics lab, along with intense pressure and long hours. After others leave for the day, Rouse and Shop Manager Dale Harris frequently work long into the night on classified projects. When their energy begins to flag, they retreat to a nearby all-night diner for ham and eggs to sustain them for a few more hours of work. Around 3 am, they head home for an hour or two of sleep before returning for another day. Occasionally this research was visible to passers-by — case in point, studies of firefighting nozzles for use on U.S. ships conducted in the Iowa River outside the lab. IIHR helped develop nozzles that produced a more focused, powerful water stream that was more effective at putting out fires.

1940s Rouse says that while there is nothing wrong with teaching the use of gauges, calibration of flow meters, measurement of head loss in a pipe, and the like, “the error lies in disregarding the fact that [the engineer] needs to know a great deal more.” (photo: H-Rouse Teaching Cavitation Tunnel) Rouse initiates the first formal fluid mechanics teaching laboratories at the University of Iowa. He designs, constructs, and tests teaching instrumentation at IIHR. For example, in the early 1940s, Rouse designs and builds a complex pipe system to determine resistance to flow through smooth and rough pipes. For decades, this experiment occupies part of the first floor in the C. Maxwell Stanley Hydraulics Lab. A refurbished version is still in use today in the new Fluids Lab.

Iowa Flood Ce Helping Iowans Become More Flood-Resilient 4 4 • IIHR Cu rr ents


2009

After the catastrophic flood of 2008, the Iowa Legislature creates the Iowa Flood Center (IFC), as proposed by IIHR’s Witold Krajewski and Larry Weber. Krajewski is the first director of the IFC, which provides Iowans with accurate, scientific information to help them better understand and prepare for their flood risks with improved flood monitoring and prediction. Through collaborations with communities, individuals, government agencies, and decision-makers, IFC brings engineering and scientific expertise to flood-related issues. In 2011, the IFC launches the Iowa Flood Information System (IFIS), which puts data directly in the hands of the people who need it — emergency managers, public safety personnel, and the general public. With this information, Iowans can make better decisions to protect their property, their families, and their livelihoods.

‘‘

It was the opportunity to have a team, to set a technical vision for the center, and then get people on board—experts, faculty, researchers, engineers, to work toward the vision.

Expanding IIHR’s Expertise Below Ground 4 8 • IIHR Cu rr ents


2014

The Iowa Geological Survey (IGS) begins a promising new partnership with IIHR. IGS has a long and storied history in Iowa dating back to 1855, when it was created by the Iowa Legislature. IGS scientists bring new capabilities to IIHR, including the mapping of Iowa’s earth and mineral resources, innovative geophysics skills, groundwater modeling, and more. These capabilities, in collaboration with IIHR’s expertise in fluids-related research, contribute to new research advances in hydrological and surface water processes, including river mechanics and watershed processes. This new partnership creates an organization with expertise that covers all aspects of Iowa’s hydrologic cycle — precipitation, evaporation and evapotranspiration, surface flow, infiltration, and groundwater flow. As water becomes an evermore-precious commodity, many Iowa cities, industries, and livestock producers turn to the IGS for expertise on modeling and management of water resources.

2016 The U.S. Department of Housing and Urban Development (HUD) awards nearly $97M to the state of Iowa for the “Iowa Watershed Approach (IWA) for Urban and Rural Resilience.” This statewide watershed improvement program slows down water moving through the landscape by building farm ponds, wetlands, and other conservation practices in the watershed. IWA restores some of Iowa’s natural resiliency to heavy rainfall, while also improving water quality, adding natural beauty to the landscape, creating wildlife habitat, and restoring ecosystem services.
