    for a serious problem to develop As a critical resource that touches so many aspects of our society it makes sense to address the sustainability of water resources in a multidisciplinary manner Iowa is also ripe for change The severe floods of the last 20 years have created a population eager to learn how to better manage water resources says Cwiertny You have a community now that s going to be receptive I think and acutely aware of how water impacts them IIHR Associate Research Scientist Craig Just center with members of the UI s Sustainability Living Learning Community Cluster Power How does a collaboration between eight academics from very different fields work in the real world Although the cluster is relatively new so far it s working very well IIHR Research Engineer Jerry Schnoor the group s mentor leader has organized regular water sustainability seminars with a different cluster member presenting his or her work at each meeting We get to know each other understand our complicated research interests look for the synergies and look for the opportunities we can pursue together says Cwiertny He s organizing more casual get togethers so they can also talk more under relaxed circumstances Cwiertny is especially glad to see communication and policy experts among the cluster s members The ability to communicate is going to be really important he says We can develop the best technologies and engineering strategies but they don t get very far until it can be implemented as smart policy that people can support and buy into And change their behavior adds Just He believes sustainability is a behavioral issue rather than a resource or knowledge issue Changing behavior in the modern media world requires savvy communication The research has to be brought to life in communities through engagement and communication And collaborating can be fun For a native Californian like Cwiertny it was a no brainer to leave sunny California for Iowa and this professional opportunity I really do believe that we re doing good things and important things he says Plus your job has to be fun I will tell you I m having great fun in the time I ve been here at Iowa I get to learn new things all the time when I interact with people from other disciplines Just says He adds that learning to speak the languages with colleagues from other disciplines all English but still very different can be challenging But it s a challenge I m up for Tags Aaron Strong Adam Ward Ananya Sen Gupta Craig Just David Cwiertny Eric Tate Hans Joachim Lehmler IIHR Kajsa Dalrymple UI research Water Sustainability Initiative Last modified on June 25th 2015 Posted on October 2nd 2013 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

    low energy flow field and actively trying to reach the ocean When the energy level in the flow gets high or the velocity gets higher it turns around and swims tail first Weber explains If it gets bad enough that they want to escape they re pointed in the right direction Wanapum Dam fish bypass Using new acoustic data researchers were able to accurately triangulate the positions of the fish and learn more about their behavior near the dam They found that fish swimming up to a guide wall even at night would track along it until they sensed a change in the flow they didn t like They couldn t see it Weber says They were responding to the flow field They also noticed that the fish seemed to dislike rapid flow acceleration The fish sense that acceleration and they re avoiding it he explains They re going in tail first and thinking Oh this isn t right After retreating the fish mill around and may go up to the dam to test the waters again We have records of fish going up and trying this four or five times Weber says Some fish eventually choose to go through the turbines instead Think Like a Fish The question is why Apparently Weber says they prefer the smoothness of the flow acceleration up to the turbine According to Nestler what matters is the hydrodynamic environment a fish experiences Andy Goodwin wrote algorithms that reflected this new knowledge Their resulting computer model known as the Numerical Fish Surrogate was an important breakthrough It s the only model of its kind Weber explains We continue to apply it at a number of different dams These insights led to new fish passage designs with flared entrances to make the flow accelerations more gradual As important as the Numerical Fish Surrogate is Weber says it needs to be accompanied by good engineering judgment good biological judgment and careful laboratory and numerical simulations It s not the only tool in our toolbox Weber says The fish passage system now in use at the Wanapum Dam in Washington State was developed using this combination of scientific tools and methods It has helped the utility achieve a 95 percent survival rate for fish passing the dam Total Dissolved Gas TDG Modeling Website Tags dams fish passage IIHR Larry Weber Wanapum Dam Last modified on June 25th 2015 Posted on January 18th 2011 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
