Civil and Environmental Engineering Undergraduate Honors Thesis Defense: Corina Overman
Wednesday, August 16, 2017 - 2:00pm

The Department of Civil and Environmental Engineering is pleased to announce Corina Overman's Honors Thesis Defense: "A Statistical Model of Lower Columbia River Water Temperature, 1938-2003." 

Date: Wednesday, August 16, 2017
Time: 2:00pm
Location: Engineering Building 202L (CEE Conference Room)
Adviser: Dr. Stefan Talke

The Columbia River is home to anadromous salmon populations that migrate upriver every year to spawn. In recent years, high summer water temperature in the Columbia River has caused an increase in salmon mortality. Different possible explanations for increased water temperature include climate change, deforestation, and decreased streamflow due to dams. In this study, robust linear regression models of water temperature at Bonneville Dam based on air temperature in the Columbia Basin and discharge at The Dalles were developed. Comparison of historical and modern models provided a way to examine the change in water temperature over time and assess the contributions of different factors to increased water temperature.
