Plot a summary of model results for a single sub-basin

Description

Plot a standard suite of plots summarizing properties of a sub-basin including upstream area and model performance for discharge and concentrations of nutrients, sediment, and tracers.

Usage

PlotBasinSummary(
  x,
  filename,
  driver = c("default", "pdf", "png", "screen"),
  panels = 1,
  gd = NULL,
  bd = NULL,
  gcl = NULL,
  psd = NULL,
  subid = NULL,
  desc = NULL,
  timestep = attr(x, "timestep"),
  hype.vars = "all",
  from = 1,
  to = nrow(x),
  log = FALSE,
  xscale = "gauss",
  start.mon = 10,
  name = "",
  ylab.t1 = "Conc."
)

Arguments

x	Data frame, with column-wise daily time series of HYPE variables. Date-times in POSIXct format in first column. Typically an imported basin output file from HYPE using ReadBasinOutput. See details for HYPE output variables required for plotting.
filename	String, file name for plotting to file device, see argument driver. No file extension! Ignored with plotting to screen device. Device dimensions are currently hard-coded, see Details.
driver	String, device driver name, one of default, pdf, png, or screen. Defaults to default, which plots using default plotting device getOption("device").
panels	Integer, either 1, 2, or 3, indicating which panels to plot. See Details.
gd	A data frame, containing 'SUBID', 'MAINDOWN', and 'AREA' columns, e.g. an imported 'GeoData.txt' file. Only needed with bar chart panels, see Details.
bd	A data frame, containing 'BRANCHID' and 'SOURCEID' columns, e.g. an imported 'BranchData.txt' file. Optional argument. Only needed with bar chart panels, see Details.
gcl	Data frame containing columns with SLCs and corresponding land use and soil class IDs, typically a 'GeoClass.txt' file imported with ReadGeoClass. Only needed with bar chart panels, see Details.
psd	A data frame with HYPE point source specifications, typically a 'PointSourceData.txt' file imported with ReadPointSourceData. Only needed with bar chart panels, see Details.
subid	Integer, SUBID of sub-basin for which results are plotted. If NULL (default), a subid attribute is required in x. Only needed with bar chart panels, see Details.
desc	List for use with type. Class description labels imported from a 'description.txt' file, for bar labeling. See ReadDescription for formatting details. Only needed with bar chart panels, see Details.
timestep	Character string, timestep of x, one of "month", "week", "day", or "nhour" (n = number of hours). If not provided, an attribute timestep is required in x.
hype.vars	Either a keyword string or a character vector of HYPE output variables. User-specified selection of HYPE variables to plot. Default ("all") is to plot all variables which the function knows and which are available in x. See details for a list of known variables. Other possible keywords are "hydro" and "wq" (water quality), for which a pre-selected range of (available) result variables is plotted. Alternatively, a character vector holding HYPE output variable IDs to be plotted. Variables unknown to the function will be ignored with a warning.
from, to	Integer or date string of format \ interpreted as row indices of x.
log	Logical, log scaling discharge and concentrations.
xscale	Character string, keyword for x-axis scaling. Either "lin" for linear scaling or "gauss" for gaussian scaling. See description in PlotDurationCurve.
start.mon	Integer between 1 and 12, starting month of the hydrological year. For regime plots, see also AnnualRegime.
name	Character or expression string. Site name to plot besides bar chart panels. Only relevant with panels 1 or 3.
ylab.t1	String or plotmath expression, y axis label for T1 tracer time series panel (tracer concentration units are not prescribed in HYPE).

Details

PlotBasinSummary plots a multi-panel plot with a number of plots to evaluate model properties and performances for a chosen sub-basin. Performance plots include discharge, HYPE-modeled nutrient species for nitrogen (total, inorganic, organic) and phosphorus (total, particulate, soluble), and HYPE modeled suspended and total sediment concentrations.

Plotted panels show:

• Summarized catchment characteristics as bar charts: Upstream-averaged land use, soil, and crop group fractions; modeled nutrient loads in sub-basin outlet, and summed upstream gross loads from point sources and rural households (if necessary variables available, omitted otherwise).

• Goodness-of-fit measures for discharge and concentrations: KGE (Kling-Gupta Efficiency), NSE (Nash-Sutcliffe Efficiency), PBIAS (Percentage Bias, aka relative error), MAE (Mean Absolute Error), r (Pearson product-moment correlation coefficient), VE (Volumetric Efficiency).

• Simulation-observation relationships for discharge and concentrations: Simulated and observed concentration-discharge relationships, relationship between observed and simulated nutrient, sediment, and tracer concentrations.

• Duration curves for flow and concentrations: Pairwise simulated and observed curves.

• Annual regimes for flow and concentrations: Pairwise simulated and observed regime plots at monthly aggregation, with number of observations for concentration regimes.

• Corresponding plots for IN/TN and SP/TP ratios.

Per default, the function plots from available model variables in an imported HYPE basin output file, and missing variables will be automatically omitted. Variable selection can be additionally fine-tuned using argument hype.vars.

Argument panels allows to choose if bar chart panels should be plotted. This can be time-consuming for sites with many upstream sub-basins and might not necessary e.g. during calibration. If 1 (default), all panels are plotted. If set to 2, bar charts will be excluded. If 3, only bar charts will be plotted. Arguments gd, bd, gcl, psd, subid, and desc are only needed for bar chart plotting.

#' Device dimensions are hard-coded to a width of 13 inches and height depending on the number of plotted time series. When plotting to a screen device, a maximum height of 10 inches is enforced in order to prevent automatic resizing with slow redrawing. PlotBasinOutput throws a warning if the plot height exceeds 10 inches, which can lead to overlapping plot elements. On screens with less than 10 inch screen height, redrawing is inhibited, which can lead to an empty plot. The recommended solution for both effects is to plot to pdf or png file devices instead.

Value

Returns a multi-panel plot in a new graphics device.

Examples

# Source data, HYPE basin output with a number of result variables
te1 <- ReadBasinOutput(filename = system.file("demo_model", "results", "0003587.txt",

te2 <- ReadGeoData(filename = system.file("demo_model", "GeoData.txt", package = "HYPEtools"))

## Not run: 
# Plot basin summary for discharge on screen device
