Using Fiberoptics to Measure Water Temperature

The video discusses the challenges faced in water resource engineering, particularly in the Western Cascades, where low elevation mountains are experiencing less snow and more rain. It highlights the impact of these changes on streams, groundwater, and downstream users, including agricultural and urban areas. The video also explores the role of manmade structures like dams and the use of fiber optic technology to measure temperature changes in streams. This technology helps pinpoint cold water sources and model the entire system to address environmental issues effectively.
