Analyzing Stream Discharge Trends: A Comparison of Streams A, B, and C

Compare stream discharge for Stream A, B, C

We compared the stream discharge for Streams A, B, and C using a line plot. Here are the key observations:
  • Stream A generally has the highest discharge among the three streams.
  • Stream B follows Stream A with a lower discharge rate.
  • Stream C has the lowest discharge rate throughout the observed period.
The line plot visually illustrates the differences in discharge rates over time, providing a clear comparison of the streams' behaviors.

Analyze trends in stream discharge over specific time periods

We analyzed trends in stream discharge over specific time periods by calculating the yearly average discharge for Streams A, B, and C. Here are the key observations:
  • Stream A: Shows fluctuations over the years with a noticeable increase in 2021.
  • Stream B: Similar to Stream A, it fluctuates but also peaks in 2021.
  • Stream C: Generally, shows a gradual increase in discharge over the years, with the highest average discharge in 2021.
This analysis indicates that all three streams experienced an increase in discharge rates in 2021, suggesting a trend of rising water levels during this period.

Plot and interprete the wavelet analysis for each stream

To perform a wavelet analysis, we'll first compute the wavelet transform for each stream's discharge data. This will help us understand the frequency components over time. After computing the transforms, we'll plot them to visualize the changes in frequencies. Let's start with the computation and visualization for each stream.
We performed a wavelet analysis for each stream (A, B, C) to identify frequency components over time. Here's a summary of the findings from the wavelet transform plots:
  • Stream A: Exhibited variations in frequency components over time, indicating changes in discharge patterns.
  • Stream B: Similar to Stream A, showed fluctuations in frequency components, suggesting variability in discharge rates.
  • Stream C: Demonstrated a different pattern compared to Streams A and B, with its own unique fluctuations in frequency components.
These wavelet transform plots provide a detailed view of the temporal changes in discharge rates for each stream, highlighting periods of high and low frequency components which can be linked to environmental or seasonal factors affecting water flow.

Compare the stream before and after 2013

To compare the streams before and after 2013, we'll split the data into two periods: before 2013 and from 2013 onwards. Then, we'll calculate the average discharge for each stream in these two periods and compare the results to identify any significant changes.
We compared the average stream discharge before and after 2013 for Streams A, B, and C. Here are the key findings:
  • Stream A: Average discharge increased from 8.49 to 9.42 cubic meters per second.
  • Stream B: Average discharge rose from 5.66 to 6.73 cubic meters per second.
  • Stream C: Average discharge remained almost the same, changing slightly from 1.06 to 1.06 cubic meters per second.
This comparison indicates an increase in discharge for Streams A and B after 2013, while Stream C's discharge remained stable.

Explore correlation between stream discharge and rainfall

To explore the correlation between stream discharge and rainfall, we need data that includes rainfall measurements alongside the stream discharge data. Could you please provide the rainfall data or confirm if it's included in the current dataset? If it's not available, we can simulate rainfall data to demonstrate how such an analysis would be conducted.

Visualize this for me

Since we don't have actual rainfall data, we'll simulate rainfall measurements to demonstrate how to explore the correlation between stream discharge and rainfall. This will involve generating synthetic rainfall data, merging it with the stream discharge data, and then visualizing the correlation between them for each stream.
We visualized the correlation between stream discharge and simulated rainfall data for Streams A, B, and C. Here's a summary of the visualization:
  • Stream A Discharge vs Rainfall: The plot shows the discharge and rainfall over time, allowing us to observe periods where high rainfall might correlate with increased discharge and vice versa.
  • Stream B Discharge vs Rainfall: Similar to Stream A, this plot enables us to identify potential correlations between rainfall and discharge rates.
  • Stream C Discharge vs Rainfall: This plot also displays the relationship between rainfall and discharge, although Stream C's discharge rates are generally lower than A and B.
The visualization helps in understanding how rainfall could potentially influence the discharge rates of each stream, although actual data analysis would be required to confirm any specific correlations.
