  • George Constantinescu: Rivers Run in the Family – IIHR – Hydroscience & Engineering – University of Iowa
    to apply to the University of Iowa and IIHR to pursue a PhD Turbulent Flows Constantinescu s research continues to focus on using eddy resolving numerical simulations to predict and understand the physics of turbulent flows He explores how the presence of vortices and large scale turbulence can be used to explain transport and mixing in rivers particularly with regard to flow and local scour around hydraulic structures Another area of interest is stratified turbulence and in particular the mixing processes that occur when two or more fluids with different densities meet With modern supercomputers Constantinescu explains it s possible to apply eddy resolving techniques that were originally developed in aerospace engineering to river engineering problems The Coming Revolution He predicts the next 10 to 15 years will be quite revolutionary in his field It s going to be quite an exciting time for research Constantinescu says He is also interested in the area of eco hydraulics which explores the effect of flow on plants fish and other living organisms in natural streams IIHR is a leader in this area thanks to the pioneering work of Jacob Odgaard and Larry Weber on the design of fish friendly passage structures at hydropower dams Constantinescu says It s an interdisciplinary field that brings together engineers biologists chemists and more Advanced techniques in numerical modeling now make it possible to simulate almost all the processes in a natural stream including nutrient and sediment transport biological processes and more simultaneously Constantinescu s keen interest in research is supported by his work as a teaching faculty member He has developed several graduate courses in his areas of research interest and he says teaching these classes is particularly rewarding He also appreciates the opportunities to travel that come with being a researcher and faculty member and he frequently travels for pleasure as well To Paris Mais oui Tags bridge scour George Constantinescu Hunter Rouse hydraulics IIHR John Kennedy UI engineering Last modified on June 25th 2015 Posted on May 20th 2014 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

  • Jacob Odgaard: Making an Impact – IIHR – Hydroscience & Engineering – University of Iowa
    a position with the United Nations and later a postdoc at Cambridge U K Next came a job at the Danish Hydraulic Institute which took him to nearly all corners of the world His only regret he says is that he didn t take time to see more of the countries he visited his focus on work was too intense At IIHR that focus did not relent Odgaard has worked on an astonishing number of research projects including some of the institute s most influential work Submerged Vanes For Odgaard perhaps the most exciting moment of his career came unexpectedly one afternoon at Oakdale where he was running experiments in a curved sediment flume The U S Army Corps of Engineers had commissioned him to study bend scour and bank erosion and ways to prevent it Based on an earlier model study Odgaard and Kennedy wondered what effect small submerged vanes or foils might have on the bend scour if correctly aligned Odgaard asked Mechanical Shop Supervisor Jim Goss to cut seven pieces of metal which he placed in the flume slightly angled to the flow Odgaard was astonished by what he saw They actually started moving sediment out to the bank He called Kennedy and asked him to come see for himself The vanes completely flattened the bed eliminating all the scouring It was fantastic Odgaard says Neither Jack nor I really thought they would work that well Together they wrote the first journal paper on submerged vanes and the complex flow patterns they create which can reduce scouring along riverbanks It was groundbreaking work still in use today although Odgaard says vanes are not the solution for all bank erosion problems For certain problems they can certainly do the job he says Odgaard also started fish passage research at IIHR in 1981 which has grown to be one of the institute s most important research areas We started out knowing absolutely nothing about how to deflect these baby salmon Odgaard says Odgaard and his team worked with clients in the Pacific Northwest to help guide fish safely through hydroelectric dams This was very rewarding because we learned so much about complex flow patterns in water intakes Odgaard says When Odgaard was approached for a position as associate dean in the College of Engineering he did not accept right away I didn t want to be a paper shuffler he says That was not me He preferred to do work with more concrete results But when he learned that he could influence the college s plans for expanding and renovating the engineering facility he saw that this work could have a tangible impact on generations of students It really became interesting he says The more impact the better Odgaard continues his teaching and research and shows no signs of slowing down When he s not at work he enjoys serving as a flight instructor and spending time with his family Even today when faced with a dilemma Odgaard thinks
