September 1998

This report of the activities of the Iowa Institute of Hydraulic Research (IIHR) covers theperiod July 1997 through June 1998, which coincides with The University of Iowa’s fiscal year.Lists of the active grants, publications, conference presentations, theses and awards of IIHR staffand students are included. Some other highlights and accomplishments of the period aresummarized below.

One of the unquestioned highlights of the report period was the success of the first courseon International Perspectives in Water Resources Planning. This course was developed by IIHRin collaboration with two universities in India, Dharamsinh Desai Institute of Technology,Nadiad, Gujarat and University of Roorkee, Roorkee, Uttar Pradesh. It involved weeklymeetings and seminars at IIHR that focused on how cultural, historical, societal, economical andpolitical considerations have impacted water resources development in India and culminated in a20-day visit to India between semesters of the academic year. Eleven students (ten from TheUniversity of Iowa (UI) and one from a Florida university) participated in the course.

Other new international initiatives included the effectuation of cooperative agreementswith Danish Hydraulic Institute, which has resulted in reciprocal visits and plans for substantivecollaborations, and Istituto Nazionale per Studied Esperienze di Architecturi Navale (INSEAN)in Italy. The INSEAN agreement promotes cooperation between it and IIHR on research thatcombines computational and experimental ship hydrodynamics and uncertainty analysis. Also,IIHR hosted students from abroad under agreement for them to conduct their thesis research herewhile receiving their degrees from their home institutions. These included two students fromKaiserslautern in Germany and one from Danish Maritime Institute.

Work on the Iowa Mobile Rainfall Laboratory, comprising vertically pointing radar withdoppler capability, a disdrometer for rain-drop analysis, and rain gages mounted on a speciallyequipped trailer, was completed. This facility allows IIHR’s participation in the currentTEFLUNB field experiment, which is part of the Tropical Rainfall Measurement Mission(TRMM), in Florida. The mobile laboratory with its specialized instrumentation can be towed toexperimental sites across the nation.

IIHR underwent an external review during the report period. This included a self-review,as well as a review by a committee external to IIHR. The external review report affirmed IIHR’smission and research and suggested areas, such as environmental fluid mechanics, in which IIHRis well positioned to focus future research efforts. Other suggestions related to the necessity forIIHR better to promote itself and to the need for UI assistance to accelerate the modernization ofthe Hydraulics Laboratory Building.

Construction was completed on the extension of the Wind Tunnel Annex mezzanine,which added 1,655 sq ft to IIHR’s floor space. The university approved the use of space justwest of the Model Annex for construction of an undergraduate fluids laboratory and designs arebeing considered for it.

IIHR expended a total of $3,717,213 during FY 1998 in pursuit of its education andresearch mission. Of this amount, $2,298,563 was expended for research through grants andcontracts proposed and administered by IIHR staff and $1,186,748 was expended for IIHR’sadministration and laboratory and equipment maintenance. The remaining $231,902 wasinvested by IIHR in its infrastructure ($11,168 for construction and remodeling and $220,734 forequipment). IIHR received an additional $150,000 in equipment- and renovation-matchingfunds from the university and college administrations.

The IIHR staff looks forward to the challenges and rewards that surely will presentthemselves in 1998-99.
