rvn_rvh_summarize {RavenR}R Documentation

Summarize RVH object

Description

Summarizes the RVH object provided in a number of useful ways, and returns a list with the summarized information.

Usage

rvn_rvh_summarize(rvh = NULL, return_list = TRUE)

Arguments

rvh

rvh object as returned by rvn_rvh_read or rvn_rvh_query

return_list

boolean whether the to return the summary list object, if FALSE only TRUE is returned (default TRUE)

Details

The total subbasin area is the total area of all subbasins in the RVH object. If there are multiple outlets in the model, or additional subbasin information that is not part of the model domain, this will be counted in the total area and other summary diagnostics. Consider using rvn_rvh_query to isolate portions of the domain in such instances.

Information for dominant Terrain and Aquifer classes is also returned, but only if there are Terrain or Aquifer classes respectively other than '[NONE]'. The number of unique HRUs include Terrain and Aquifer classes in the consideration of unique HRUs if there are instances of classes other than '[NONE]' for these classes.

Value

Returns TRUE if the parameter return_list is FALSE, otherwise returns a list with multiple items:

total_subbasin_area

total subbasin area, computed as the sum of all areas in rvh$SBtable$Area

num_subbasins

total number of subbasins

num_hrus

total number of HRUs

num_unique_hrus

total number of unique HRUs, i.e. HRUs with unique combination of LandUse, Vegetation, Soil Profile, and Terrain/Aquifer if relevant (see details)

Examples

# load example rvh file
nith <- system.file("extdata","Nith.rvh",package = "RavenR")
rvh <- rvn_rvh_read(nith)

# summarize rvh
rvn_rvh_summarize(rvh, return_list=FALSE)

# query of HRUs upstream of basin 39, then summarize
rvh %>%
  rvn_rvh_query(subbasinID=39, condition="upstream_of") %>%
  rvn_rvh_summarize(return_list=FALSE)
