The Department of Civil and Environmental Engineering is pleased to announce Michael Waxter's MS Project Presentation: "Analysis of LANDSAT Satellite Data to Monitor Water Quality Parameters in Ten Mile Lake, Oregon."
Date: Thursday, June 5, 2014
Location: Engineering Building 202L (CEE Conference Room)
Adviser: Dr. Stefan Talke
The health of Tenmile Lakes in coastal Oregon has been on the decline since the introduction of invasive species of fish and plant life, including yellow perch and Elodea. The lakes are now on the Federal Clean Water Act list of impaired water bodies due, in part, to lack of dissolved oxygen and Hazardous Algae Blooms (HAB) blooms that occur during June through September. In this talk we discuss the possibility of detecting and monitoring these blooms using satellite measurements of water surface color. In-situ measurements obtained from the Tenmile Lakes Basin Partnership were used to calibrate reflectance from the Thematic Mapper on the LANDSAT 5 satellite. Results show a very good linear correlation between turbidity and reflectance which are inversely related in algae dominated lakes. Additionally, a correlation between biovolume and reflectance was obtained, however, the ability to predict bio-volume from satellite reflectance data is complicated by large amounts of organic matter in Tenmile Lake.
