As part of the 2019 Water Quality Study, the field team conducted a longitudinal analysis of the Lower Deschutes River by rafting the river July 15 to 21, 2016 from the ReReg tailrace (RM 100) to the mouth of the river (RM 0.1).
The following figures depict data collected during this river float.
Combined Eulerian and Lagrangian viewpoints of simulated and observed temperature dynamics in the LDR. Plots labeled A1–A4 represent time series data of observations (in orange) and model results (in blue) at individual locations in the system. The vertical black line in each of the plots defines the point in time where the B and C snapshot figures were taken. Plots B1 and B2 outline the temperature at a particular moment in time for all locations in the LDR. The red dots in B2 are the observations at that point in time, at different gauged locations on the river. The colors in B1 represent the water temperature at a single point in time. Plot C represents the floating (Lagrangian) temperature observations in orange, with the modeled observations at each point in time and space in blue. Note that the two periods of time when the observations (orange) disappear correspond to gaps in the observed data.
Combined Eulerian and Lagrangian viewpoints of simulated and observed DO dynamics in the LDR. Plots labeled A1–A4 represent time series data of observations (in orange) and model results (in blue) at individual locations in the system. The vertical black line in each plot defines the point in time where the B and C snapshot figures were taken. Plots B1 and B2 outline the DO at a particular moment in time for all locations in the LDR. The red dots in B2 are the observations at that point in time, at different gauged locations on the river. The colors in B1 represent the DO at a single point in time. Plot C represents the floating (Lagrangian) DO observations in orange, with the modeled observations at each point in time and space in blue. Note that the two periods of time when the observations (orange) disappear correspond to gaps in the observed data.
Combined Eulerian and Lagrangian viewpoints of simulated and observed pH dynamics in the LDR. Plots labeled A1–A4 represent time series data of observations (in orange) and model results (in blue) at individual locations in the system. The vertical black line in each plot defines the point in time where the B and C snapshot figures were taken. Plots B1 and B2 outline the pH at a particular moment in time for all locations in the LDR. The red dots in B2 are the observations at that point in time, at different gauged locations on the river. The colors in B1 represent the pH at a single point in time. Plot C represents the floating (Lagrangian) pH observations in orange, with the modeled observations at each point in time and space in blue. Note that the two periods of time when the observations (orange) disappear correspond to gaps in the observed data.
