Center for Infrastructure Modeling and Management

The Teaming Organizations


About Us

Going forward, the team striving to create a sustainable Center for Infrastructure Modeling and Management (Center) will expand to include a wide range of academic, private and public sector entities.  As a starting point, however, the team includes representatives from several institutions that broadly come under the umbrella of two lead organizations - the University of Texas at Austin (UTA), and the Urban Watersheds Research Institute (UWRI).  Key participating institutions under this umbrella are Brigham Young University, Texas Tech University, and North Carolina State University.  And, of course, the US Environmental Protection Agency has a pivotal role not only as the source of funding for this venture, but as a source of advice and as a foremost regulatory agency supporting the goals and objectives of the program.

The two lead institutions, UTA and UWRI, have elected to balance Center functions between them.  Research functions are focused under the leadership of UTA led by Program Principle Investigator Dr. Ben Hodges, while Center development functions such as training, coding, development and support functions are focused under the UWRI, led by Dr. Charles Rowney.  Between them, the two lead organizations provide a comprehensive ability to develop and launch the Center.  To prevent an inefficient schism between the lead entities, Drs. Hodges and Rowney have complementary roles in the research and Center development functions, and several team members operate on both sides of this program as well.  This arrangement is advantageous in that it efficiently meshes the merits of a proven academic institution well positioned to further the research needs of this program, with the benefits of an equally solid non-profit corporation able to interact to good effect with communities, partners, and research requirements so as to address the development needs of the Center.
