Weather Source + Conditions

Weather Underground: The total accumulation of precipitation during the recording of this experiment in 8.1 inches of rain. Tuesday, July 15th, had the most downpour with 1.95 inches of rain.

Sensor Location Notes

  • Upstream: The sensor was under accumulated amounts of debris which seemed to flow downstream during storms but got caught on the rebar. This caused a pileup.
  • Middle Stream: The Sensor here exhibited the same issue as the upstream sensor and experienced the same debris pileup.
  • Downstream: this Sensor was below water level with no debris pileup.

Wildlife Observered

  • Beach Trees
  • Deer
  • White Ash

Bank Stability

No bank stability In the upper stream portion. more fallen trees reside upstream along with little to no water insight. Upstream was covered in multiple fallen trees along the stream path. Downstream there were riffles that conducted smoother flow along the river. There were also exposed tree roots which also play a role in the bank stability.

Flow Speed Estimate

no speed was seen from upstream location. Downstream had moderate flow speed.

Plots

Analysis

The data show that the upstream sensor had the lowest temperature frequency of all the sensors. There were several contributing factors that reason this due to field observations. Due to a combination of canopy shading and debris accumulation around the sensor ultimately limited any daytime warming of the sensor. These conditions are what prompted the upstream sensor to be generally cooler during this study period.

Daily Temperature Mean

Upstream is expectantly experiencing more heat than the rest of then sensors.Both the middle and downstream stay relative to one another. The upstream sensor is generally cooler but experiencing more variability.

3-day Close-Up

Same observations but with the addition of the upstream sensor cooling consistently more than the other sensor which could mean extended shading.

1-day Close-Up

While the mid and downstream sensors seem relative to one another, the upstream sensor is constantly getting colder. This signifies that there is another input cooling the sensor, possibly groundwater.
