Literature reviews on various stream processes which contribute to reoxygenation and deoxygenation was presented. These processes include atmospheric reaeration, photosynthesis-respiration, biochemical oxygen consumption, and benthic demand. Measuring these parameters in a selected stream is a complex and costly operation. On the other hand, prediction models developed are specific to particular location and environmental conditions and can only be applied to similar situations. Computer models such as "RIVER" are available and could be used to predict dissolved oxygen concentrations along a waterway for a specified set of stream conditions. The model "RIVER" was calibrated by using the existing conditions of flow and water quality parameters along Phillippi Creek, Sarasota County, Florida. Also treatment requirements which could eliminate dissolved oxygen violations were predicted.

This creative project has culminated in a design solution to a water quality problem in the City of Indianapolis, Indiana. Pogues Run is a stream that has been buried in an underground culvert for almost a century. It has a long history of water quality problems including high bacteria levels and nonpoint source pollution. In addition, it has long been a flood threat to neighboring communities.To address the issue, a master plan was created for the last 1400' of Pogues Run before it emptied into the White River. The stream was removed from the culvert, brought back up to grade, a series of wetlands were developed to slow and filter stream flow, and an urban revitalization project was developed centering on the stream. The design solution provided flood control, stormwater storage and treatment, mixed-use redevelopment of historical buildings, a recreational area, and a high-density residential community. / Department of Landscape Architecture
