GENERATING ROBUST SOLUTIONS - A WATER-QUALITY MANAGEMENT EXAMPLE

An approach is presented for analyzing a water quality management prob lem that consider's multiple pollutant transport responses within an o ptimization model formulation. The multiple pollutant transport respon ses represent different possible scenarios that could occur in the wat er body. Solutions to the optimization model are obtained that are rob ust with respect to the actual pollutant transport response. The desir able characteristics of the solutions obtained to this waste load allo cation problem are demonstrated through the application of the approac h to a case study based on the Willamette River in Oregon.
