July 1998 Newsletter

Dear Iowans:

Let’s see. June rain amounts exceeding those of the disastrous summer of 1993; July heat so unbearable we actually long for an Iowa winter; thunder and wind storms aplenty—must be time for IIHR’s summer newsletter. We Iowans can joke among ourselves about things such as our weather, but make no mistake about it, our experience has been that if people get beyond some silly misconceptions to give us a try, they seem to be hooked by the quality of life and the education and research environment here. Peppered throughout this letter are comments in this regard that we have received from alumni during the last few months. We anticipated just four short months ago that in resuming summer publication of this missive with so little time lapsed, we might be able to share all of the current news on a postcard. WRONG. The letter is as long and information-packed as ever, so let’s get right to it!

You recall that one of the highlights of the last letter was the report on the success of the first course in “International Perspectives in Water Resources Planning,” which was held in India. Tatsuaki Nakato (Ph.D. ’94) and Jacob Odgaard are busy planning the next course for May 1999 in Japan and Taiwan, and Jacob recently traveled to China and met with Zengnan Dong (visitor ‘83–84) and others (he also visited with Bingnan Lin (Ph.D. ’51) to discuss the year 2000 course in China. In preparing a brochure for the international course, we did a count, by country, of alumni who reside outside the United States. The largest contingent, hands down, is in Taiwan. There are 30 Iowans of the IIHR variety there! Then there is India with 19, Korea with 17, Japan and China with 15 each, and Venezuela with 12. One of our most loyal alums, C.L. Yen (Ph.D. ’67), is at IIHR for a five-week stay. He is officed here while he uses UI library facilities to compile a data base on hydraulics of high-velocity flow (cavitation, air entrainment, gate vibration, supercritical flow, and flow separation in channels). We welcomed other visitors, Hyun Goo Kim from Pohang University of Science & Technology in Korea, who is working with V.C. Patel and Ching Lin on problems related to turbulence in stratified flows; and Shigeaki Shiotani, who is on the Faculty of Fisheries of Nagasaki University. He is working with Fred Stern on problems related to numerical simulation of viscous flow with free surface around a ship model. Grzegorz Ciach (Ph.D. ’97) returned from Poland for two months this summer to work with Witek Krajewski on problems related to radar and satellite rainfall estimation and validation, before he assumes a postdoctoral research position at Oklahoma University. Misha Spasojevic (Ph.D. ’88) returned for an indefinite stay at IIHR, as he becomes involved in some computational hydraulics projects. Postdoctoral associates departing the staff since last we wrote include Yinchan Wei, who had been assisting Wilf Nixon in ice research, and Madhu Sreedhar, who, after many months of long-distance commuting, left to join his wife full time in Chicago. We said goodbye to Stephen Coleman, visitor and sediment researcher from the University of Auckland in New Zealand. He had been here for five months while we grew accustomed to his jovial nature.

New staff additions include associate research engineer Yong Lai and assistant research engineer Marian Muste (Ph.D. ’95). Yong, a 1990 graduate of Arizona State University in Mechanical Engineering, came to us from Southwest Research Institute. He has extensive experience in computational fluid dynamics, turbulence modeling and heat transfer, including engine combustion and cooling. He will work on projects in computational fluid dynamics and hydraulics to advance IIHR’s capabilities in those areas. Marian has been a postdoctoral associate here since receiving his Ph.D. and now joins the permanent staff, with his expertise in experimental methods and measurement techniques in hydraulics and fluid mechanics. He will continue to devote time to designing a new modern fluids instructional laboratory in cooperation with IIHR affiliated faculty.

IIHR continues its receptivity to cooperative projects with other research organizations. Earlier this year, IIHR and the Danish Hydraulics Institute (DHI) signed a collaborative agreement and some reciprocal visits have resulted. Larry Weber (Ph.D. ’93) of IIHR visited there for discussions last spring, and Vladan Babovic of DHI visited here. Later this month, Asger Kej, managing director of DHI, will visit. He expressed the desire, after the agreement was signed, that “meat be put on the skeleton.” It appears as if that is happening. In addition to the visits, a student from IIHR, Huei-Tau Ouyang, will begin a thesis research project that will be jointly supervised by DHI staff and faculty here. As part of a long-term cooperative effort, among IIHR, Osaka University, University of Osaka Prefecture, Hiroshima University, Yokohama National University, and Kobe University of Mercantile Marine, for the development of computational fluid dynamics and optimal-design methods relating to ship hydrodynamics, and through support of NSF, Fred Stern, and Eric Paterson (Ph.D. ’94) attended the Third Osaka Colloquium on Advanced CFD Applications to Ship Flow Hull Form Design, which was organized by Fred and Yusuke Tahara (Ph.D. ’92). CFD development in this project also involves concurrent and complementary physical experiments, conducted by experimental ship hydrodynamicist, Joe Longo (Ph.D. ’96). As a result of a cooperative agreement with Istituto Nazionale per Studied Esperienze di Architecturi Navale (INSEAN), Giulio Avanzine and Angelo Olivieri were here from Italy for two weeks working with Joe, Fred, and Eric on research that combines computational and experimental ship hydrodynamics and uncertainty analysis. Larry Weber is collaborating in fish work with ENSR Corporation, which has brought Mark Allen (M.S. ’96) back on a couple of recent occasions. Ehab Meselhe (Ph.D. ’94), assistant professor at the University of Southwest Louisiana, returned to explore some joint research projects in sediment transport modeling, and Jose Matos Silva (Ph.D. ’82) is spearheading cooperative research among several research organizations in Portugal and IIHR on water intakes. Forrest Holly and Helmut Kobus (Ph.D. ’65), on behalf of UI’s Department of Civil and Environmental Engineering and three institutes of the University of Stuttgart, signed a cooperative agreement for faculty and student exchange. This will bring an M.S. student to IIHR from Stuttgart this fall. Carlos Alonso (M.S. ’67) visited relative to a collaborative project between the U.S. Department of Agriculture’s National Sedimentation Laboratory (USDANSL) and IIHR (Rob Ettema is the researcher at this end) to evaluate erosion processes in rivers covered with ice and fixed debris. Rob has another connection to USDANSL in that he served as an external reviewer of it earlier this spring. In another interesting collaboration, Rob has teamed with researchers at Iowa State University in a study sponsored through the NASA Iowa Space Grant Consortium to investigate planar-surface (e.g., airplanes) icings, which also include phenomena related to slush formation and thermal de-icing processes.

The relevance of the research is in its product, and IIHR continues its strength in application of research. IIHR’s experimental and CFD work related to ship design and codes developed through efforts of the ship hydrodynamics research team, comprising Fred Stern, Eric Paterson, Joe Longo, Bob Wilson, Madhu Sreedhar, and several students, has been well received by Navy labs and representatives of the nation’s largest shipyards, many of whom attended a workshop at IIHR in April to view our facilities. CFD has reached a level of maturity that it is being used to design ships of the future, and IIHR is considered by expert users to be among the top developers. Allen Bradley is assisting engineers in DuPage County, Ill., in the use of an improved statistical methodology he developed to estimate flood frequencies in urban areas for floodplain mapping, and he and Anton Kruger are making use of NEXRAD radar-rainfall archives to design a rain gage network for New York City’s water supply drainage basins in the Catskills Mountains. The latter project is a unique application of remote sensing to water resource management, using newly available information to quantify spatial rainfall variations in complex terrain. Over the years, Witek Krajewski has made significant contributions to the radar-rainfall estimation algorithms used operationally by the National Weather Service with the NEXRAD weather radars. In related research, as we write, the new, unique, Iowa Mobile Hydromet Lab (vertically pointing radar with doppler capability and 2-D distrometer and rain gauges mounted on a specially equipped trailer) is in tow to Florida, where IIHR researchers will join a field campaign with researchers from NASA, NCAR, Texas A&M, and the University of Colorado. This project is known as the TEFLUNB experiment and is part of the Tropical Rainfall Measurement Mission (TRMM). The research is vital in understanding global climate, because rainfall in the tropics drives the climate system. Forrest Holly’s thorough studies and extensive thermal-plume monitoring and modeling have resulted in removal of the temperature standard for cooling water discharges from the National Pollution Discharge Elimination System permits for three power plants. S.C. Jain’s expertise in designing site-specific dropshafts for management of stormwater runoff in urban environments is sought by many cities and engineering firms, and Kent Johnson’s monitoring of the water quality in the Coralville Reservoir has to be one of the longest continuing project ever undertaken here. The Rock Island District Corps of Engineers has supported this work, begun by Professor Emeritus Don McDonald, since the early 1970s. Jeff Marshall is completing a study of vortex-body interaction, funded by ARO, and is currently initiating investigations of turbulence evolution in vortex-dominated flows and two-phase turbulent flows. These flows are basic to processes such as aircraft trailing vortices, sediment transport in river flows, and rotocraft aerodynamics, so while studies of them are fundamental in nature, it is not difficult to envision the applicability of this research to real-world situations.

IIHR underwent an internal/external review, which began last fall and just was completed and which generally affirmed IIHR’s mission and research. The external review committee was a stellar group, chaired by Willard (Sandy) Boyd, former UI president, and comprising Norman Brooks, former director of Keck Lab at Caltech and professor emeritus there; Jeffrey Koseff, professor and head of Civil and Environmental Engineering at Stanford; Richard Stanley, chairman of the board of Stanley Consultants, Inc.; Francois Abboud, head of Internal Medicine at UI; and Jon Kuhl, professor in Electrical and Computer Engineering at UI. Among the recommendations made by the external committee are to put greater emphasis in research on environmental problems, increase external promotion and advocacy, and seek UI assistance to accelerate the modernization of the HL building (our icon).

One interesting sidelight is that as part of the internal review (self-study), we surveyed IIHR graduates of the years 1992 through August 1997 for their opinions of their education and research experience here. The 33 of 56 former students who returned questionnaires rated their overall IIHR experience and the preparation it provided them for the work force to be 4.5 on a scale of 1 (lowest rating) to 5 (highest rating). There also were many comments, both positive and relating to areas in which we can improve, which have been of enormous benefit. We thought it might be interesting for you to see where some of our recent graduates have begun their careers, so attached is a list with that information.

In many of our initiatives, whether they be cooperative agreements, travel, or surveys for important information, we realize the importance of staying in touch with you. With this in mind, may we ask that you please complete and return the enclosed biosketch? We now have computer capabilities to compile a detailed directory and to store personal information, if you wish to share that. The biosketch form also is on our website (, so you can return it electronically, if you have those capabilities. Please do this so our directory includes you.

IIHR is becoming a regular conference center. It seems that we consistently are involved in organizing one conference or another, for hither or yon. (The yon include the Fourth International Symposium on Hydrologic Applications of Weather Radar, held April 5–9, 1998, in San Diego and co-organized by Witek Krajewski, Anton Kruger, and Kosta Georgakakos (staff  ’85–94) of the Hydrologic Research Center, and the Osaka conference mentioned earlier.) The success of IIHR organized conferences is due in no small measure to Twila Meder, who seems to have organization of them down to a science. Our current project is the American Towing Tank Conference, a session of which will honor Lou Landweber, in Iowa City in September 1998. If you can’t attend it, you might consider coming to Hydroinformatics 2000, which will focus on the latest scientific and technological developments in hydroinformatics, as well as presentations on state-of-the-art applications of this technology to real-world problems. This will be the fourth conference in this series, with previous ones held in Delft and at ETH in Zurich and the 1998 production upcoming next month at DHI. The Iowa City conference will be held July 23–26, 2000. If you can’t make it then, another opportunity for a conference in Iowa City surely will arise. But you know you do not need an excuse to come home to visit; drop by any time. If you need assistance of any sort, call Judy Holland of the office staff. She is always willing to help. Return of family always is such a joyous occasion. Until next year …

Other News of the IIHR Staff

Wilf Nixon’s ice research and the ice laboratories of IIHR were featured on a segment of NBC-TV’s Today show early this spring. Wilf has had a big year. He was promoted to full professor and received the College of Engineering Service Award. He also is a regular contributor to the Daily Iowan with his “Viewpoint” columns. Bill Eichinger was voted secretary of the Engineering Faculty Council, but even more important, he hit the only homerun for the octogenarian faculty team that came together in response to a softball challenge from the ASCE student chapter. Among the other courageous faculty there were Forrest Holly and Tatsuaki Nakato. V.C. Patel will be keynote speaker at the Third International Conference on Hydrodynamics in Seoul, Korea, and an invited speaker at the Seventh International Symposium on Flow Modeling and Turbulence Measurement in Taiwan, both in October. Jacob Odgaard served as external reviewer of DHI. Anton Kruger and Marian Muste were invited to an interagency (U.S. Geological Survey, U.S.  Army Corps of Engineers, Agricultural Research Service, Bureau of Reclamation, Forest Service, and Bureau of Land Management) workshop on “Sediment Technology for the 21st Century,” to present their technique of using image-based instrumentation for monitoring processes in flows with alluvial sand, which they developed. Of the several presented, their technique was ranked first and most promising of the sediment-related technologies. The book Flowing Through Time: A History of IIHR, by Connie Mutel, is moving through the production process and soon will go to the printer. It will be available in late fall 1998. Students Brian Nelson and Jeff Streitz just returned from HYDROVISION 98, an international conference held this year in Reno, Nevada, with the news that they placed first the 98 Hydropower Contest with their turbine design. They received a cash prize, scholarship funds, and a valuable experience.

Alumni News

Attention graduates circa 1951. Bill Fannon (M.S. ’51) said that Jose De Abreu-Lima (M.S. ’51) reminded him it is approaching 50 years since you received your degrees, and they want to organize some sort of commemoration. Bill had the idea of trying to pull together some biographies to publish in a newsletter or, considering its age, a sheepskin-bound manuscript. We told him that we already had planned inclusion of a biographical form in this letter, so maybe you of vintage ’51 could include more personal details for use in Bill’s effort. Many of you will remember our intransigent perambulator Fazle Karim (Ph.D. ’81), who, throughout his residence in the United States, steadfastly has refused to own a car or learn to drive. He tells us that the demands of getting the family from here to there in Tucson, Ariz., and his wife Zinnat finally convinced him a couple of years ago to invest in an automobile. Though he no longer is a purist, he still holds to principle and will not drive. That’s Zinnat’s job. Manos Anagnostou (Ph.D. ’97) will leave NASA to assume a tenure track faculty position at the University of Connecticut, where he will join Fred Ogden (staff  ’92–95), assistant professor on the staff there. Also, Manos and Svetlana, who met as UI students, were married last week. Call this the cupid capitol. Kazuki Yabushita (visitor ‘95-‘97) wrote to tell us he was married in January to someone he met in Iowa. He says the time he spent here was the best term of his life, and that he misses Iowa very much. We were surprised by a visit from Selcuk Uzuner (M.S. ’75) just a few weeks ago. He and his wife and son began their extensive tour of the United States in Iowa City, because it, according to Selcuk, is the most special place in the country. During his visit, we reflected that Turkey is not represented currently in our student body. So this is a call to all six alumni there and the expatriots in the United States with connections back home: send us your best and brightest. Jerry Schnoor and his family just returned from a trip to Switzerland and the Swiss Federal Institute of Technology in Zurich, where they saw Andreas Mueller (frequent visitor) and joined him for Sunday lunch at his house. Jerry, by the way, received the College of Engineering’s research award this year. V.C. used the occasion of graduation ceremonies at Michigan, where his son received his Ph.D., to visit Ana Sirviente (Ph.D. ’96), who is on the faculty there, and Sanjiv Sinha (Ph.D. ’96), also on the staff at Michigan, and their baby, Hana Neelam Sinha. James Robertson (Ph.D. ’41), moved 4,000 feet down the mountain, from Silverthorne to Aurora, Colo. On their departure from the heights, he and his wife were honored by the Summit County Seniors and the Breckenridge Music Institute for their volunteer work. He also was chosen as 1997 Senior of the Year by the Area Agency on Aging. He sent a letter in which he recounted his experience working with Lou Landweber at the David Taylor Model Basin in 1941 and recalled also the fish ladder studies at the Burlington Street Dam. He remembers a large catfish that had climbed up a ladder through an opening not much larger than it. Veera Rajendran (Ph.D. ’98) obtained a postdoctoral associate position in the aerospace engineering department of the University of Cincinnati. Mikio Arie (M.S. ’55) retired as president of Hokkaido Institute of Technology (HIT) on April 1, 1998, but kept the position of chair of the Board of Trustees of Hokkaido Shoshi Gakuen, an educational institution that includes HIT. George Constantinescu (Ph.D. ’98) has a postdoctoral research position at Arizona State University. Eric Paterson and Fred Stern met and celebrated with many Iowans during their Japan junket. Among them were H.T. Kim (Ph.D. ’89), Yasuyuki Toda (visitor ’88–90), K.N. Chung (Ph.D. ’89), Yusuke Tahara (Ph.D. ’92), W.J. Kim (Ph.D. ’89), Kazuki Yabushita (visitor ’95–97), and Kazuhiro Mori (visitor ’81–82). Vince Neary (Ph.D. ’95) has joined the faculty of Tennessee Technological University. He sent a photo of his newborn son, which is included in the photo section of this letter.
