Professor Emeritus Jack Delleur is the recipient of the 2007 Ray K. Linsley Award. This award was established in 1986 to recognize individuals who have made outstanding contributions in surface water hydrology. The Linsley award is given once a year to an individual selected from a pool of nominations by the Linsley Award Committee and the Executive Committee of American Institute of Hydrology. Professor Delleur joins a distinguished list of previous recipients and will be honored at the American Institute of Hydrology (AIH) Annual Meeting and International Conference to be held in Reno, Nevada, from April 22-25, 2007.

Professor Delleur's distinguished service to the School of Civil Engineering and exemplary research in hydraulics and hydrology continues on. For forty years Professor Delleur has taught graduate courses in advanced (deterministic) hydrology, statistical hydrology and subsurface hydrology and hydraulics. He founded the graduate program in Hydraulic Engineering for the School of Civil Engineering and was co-principal investigator of the NSF project that funded in part, the graduate Hydromechanics Laboratory and the undergraduate laboratory. He is the author and co-author of numerous books, papers and technical reports covering hydrologic modeling, stochastic hydrology, urban hydrology and hydraulics and is currently the associate editor of the ASCE "Hydraulic Engineering Journal".

Professor Delleur has been active in both professional and honorary societies serving as an advisor to the U.S. Geological Survey Urban Runoff Programs, reviewer for the National Science Foundation, U.S. delegate to the International Joint Committee on Urban Storm Drainage, American Geophysical Union (AGU), the American Society of Civil Engineers (ASCE) and is currently the Vice-President for the Wabash Area Lifetime Learning Association (WALLA).

He has been honored for his leadership and research as a fellow of the Indiana Academy of Sciences, recipient of the Freeman Fellow Award of the ASCE, received the 2002 ASCE Ven Te Chow award, the NSF/CNRS US-France Senior Scientists Exchange Award and the Charles Harold Bechert Award of the Indiana Water Resources Association. Professor Delleur has also established the Jacques W. Delleur Award which provides financial support for one or more graduate students to travel to a relevant scientific or professional meeting in the U.S. or abroad annually.
