StreamFlowTrend

This is a suite of R functions and vignettes used to explore the statistical underpinnings of trending annual streamflow metrics using three different methods:

1. Mann-Kendall test
2. regular linear regression
3. robust linear regression

The package contains the following function and vignettes.

stfl_function: R functions to:

• compute station specific trends using the regular regression (denoted as the LM method), the Mann-Kendall test for trend (denoted as the MK method), or a robust linear regression (denoted at the LMrob method).
• compute station specific plots of the results from above
• compute regional trends for a set of stations and give weights using all three methods
• add the regional trend to the previous plots
• create a “dot map” of the trends computed

v01-individual-station-analysis: Coming soon.

v02-collection-stations-analysis: Coming soon.

v03-regional-analysis: Coming soon.

v04-regional-analysis-AnnualStats: Coming soon.
