A project of TREE - Tualatin River Environmental Enhancement Grant Program
Through partnership between Portland State University's Geography Department, U.S. Geological Survey, and the Center for Transformative Environmental Monitoring Programs (CTEMPS), this project will collect and analyze spatially and temporally detailed summer stream temperature data over two summers. Data will be collected using Distributed Temperature Sensing (DTS) in three sub-basins of the Tualatin River basin where stream restoration and beaver dams are located. Additionally, we will analyze basin-wide stream temperature collected by multiple agencies with landscape variables likely to be associated with the variation of stream temperature in order to assess effectiveness of restoration and beaver activities on stream temperature in the study reaches.
Our project is designed to answer the following:
Our project is designed to answer the following:
Question 1
Question 1
What are the watershed attributes that control spatio-temporal variations of temperature in streams with varying degrees of disturbance?
Question 2
Question 2
To what degree do beaver restoration and riparian shading affect stream temperature?
Question 3
Question 3
How well can Distributed Temperature Sensing combined with spatial algorithms detect thermal dynamics in streams?
