Hydrologic AnalySis Package

The Hydrologic Analysis Package (HASP) can retrieve groundwater level and groundwater quality data, aggregate these data, plot them, and generate basic statistics. One of the benefits of HASP is its ability to aggregate two time-series of data into one record and generate statistics and graphics on that record. By merging two data sets together, users can view and manipulate a much longer record of data. Users can download the aggregated record and see basic statistics that have been calculated with these data. HASP also allows users to plot groundwater level trends in major aquifers as well. The explore_aquifers function allows users to pull data from wells classified in Principal Aquifers and synthesize water-level data to better understand trends.

Installation of HASP

You can install the HASP package using the remotes package.

To install the remotes package, copy the following line into R or the “Console” window in RStudio:


To install the HASP package:

                        host = "",
                        build_opts = c("--no-resave-data",
                        build_vignettes = TRUE, 
                        dependencies = TRUE)

During this installation, you may be prompted to update or install some packages. Press 3 to skip the updates, but don’t forget to update all of your packages later.

Sample workflow

Get groundwater data:

site <- "263819081585801"

#Field GWL data:
gwl_data <- dataRetrieval::readNWISgwl(site)

# Daily data:
parameterCd <- "62610"
statCd <- "00001"
dv <- dataRetrieval::readNWISdv(site,
                                statCd = statCd)

Plot data:

y_axis_label <- readNWISpCode(parameterCd)$parameter_nm
title <- readNWISsite(site)$station_nm

                       parameter_cd = parameterCd,
                       plot_title = title,
                       y_axis_label = y_axis_label)

                      parameter_cd = parameterCd, 
                      stat_cd = statCd,
                      plot_title = title,
                      y_axis_label = y_axis_label)

               parameter_cd = parameterCd,
               plot_title = title,
               stat_cd = statCd,
               y_axis_label = y_axis_label)

gwl_plot_all(gw_level_dv = dv, 
             gwl_data = gwl_data, 
             parameter_cd = parameterCd,
             plot_title = title, 
             add_trend = TRUE)

Create Groundwater Report:

create_groundwater_report(siteID = site,
                          report_name = "L_2701",
                          report_folder = "reports",
                          output_type = "html")

Running this function will create an Rmarkdown file (Rmd). In RStudio, clicking the button “Knit” at the top of the file will render the Rmd file as either an HTML or Word document.

Water-quality plots

HASP also includes a few water-quality plot options.

# Water Quality data:

qw_data <- readWQPqw(paste0("USGS-", site),
                       "Specific conductance"))

qw_plot(qw_data, CharacteristicName = "Chloride",
        plot_title = title)

Sc_Cl_plot(qw_data, plot_title = title)

Composite workflows:

More information on the composite aquifer workflow can be found vignette("Priniciple_Aquifers", package = "HASP").

#included sample data:

aquifer_data <- aquifer_data
num_years <- 30

plot_composite_data(aquifer_data, num_years)

plot_normalized_data(aquifer_data, num_years)

Installation of R and RStudio

To use the HASP package, you will need to have R and RStudio installed on your computer. This installation will only need to be done once for each computer. This link has instructions for installing R and RStudio:

Running the apps

HASP includes two interactive applications as a way to explore the functionality of this package. One has functions for exploring data from a single site, and the other has functions for exploring data from an aquifer.

For more information see vignette("shinyApp", package = "HASP").

To run the single site application, use the following code:


To run the aquifer application use the following code:
