Optimal Water Quality Management Strategies for Urban Watersheds Using Macrolevel Simulation and Optimization Models
Publication: Journal of Water Resources Planning and Management
Volume 135, Issue 4
Abstract
This paper describes the development of an optimal water quality tool for managing wet weather discharges that uses a macrolevel simulation model (i.e., the Streeter-Phelps equation) linked with a highly efficient optimization algorithm (i.e., a modified version of the Box complex method). The proposed approach can be applied to an urban watershed impaired by multiple sources of wet weather discharges. As an application, the proposed approach is used to develop optimal water quality management strategies for the Beargrass Creek watershed in Louisville, Ky.

This work was supported in part by EPA grant: Water Quality 104(b)(3); No. UNSPECIFIEDCP-97485803 as administered by the Kentucky Division of Water. In addition to staff with the Kentucky Division of Water, the writers would also like to thank professional staff with the Louisville, Metropolitan Sewer District, Tetra Tech Inc., and O’Brien and Gere, who served as partners in an ongoing project to develop both pathogen and DO TMDLs for Beargrass Creek. All of the maps in the paper were generated using data obtained from the Louisville/Jefferson County Information Consortium (LOJIC) through its participating partner, Louisville MSD. This paper is dedicated to the memory of Dr. G. V. Loganathan who was tragically killed on April 16, 2007. Dr. Ormsbee was a suite mate and close friend of G. V. during the time they pursued their doctorates at Purdue University in the early 1980s. G. V. had extensive research interests in urban hydraulic infrastructure, including wet weather management, a topic which he actually worked on while at Purdue. Ironically, Dr. Ormsbee was first introduced to the Box Complex method in 1979 while working on his MSCE at Virginia Tech under the direction of Dr. Dinshaw Contractor, who subsequently left Virginia Tech to go to the University of Arizona. Dr. Loganathan was then hired as a new water resources faculty member by Virginia Tech in 1982.
