streamDepletr is an R package with functions for assessing the impacts of groundwater pumping on streams. There are two primary categories of functions:
hunt
,
glover
, hantush
, intermittent_pumping
)apportion_inverse
,
apportion_web
, apportion_polygon
, apportion_wedge
)depletion_max_distance
, prep_reach_dist
,
streambed_conductance
)Combined, these functions will allow the user to estimate the impacts of an existing or proposed well (or group of wells) on individual stream reaches within a stream network.
You can install streamDepletr from CRAN:
install.packages("streamDepletr")
Alternately, you can use devtools
to install the development version:
devtools::install_github("FoundrySpatial/streamDepletr", build_vignettes=T)
Calculate and plot streamflow depletion as a fraction of the pumping
rate (Qf
) over the 100 days of pumping:
require(streamDepletr)
#> Loading required package: streamDepletr
# calculate depletion fraction
Qf <- glover(t = seq(1,100), # timesteps to evaluate
d = 150, # well to stream distance
S = 0.10, # specific yield
Tr = 50*1e-5*86400) # 50 m thick aquifer with hydraulic conductivity of 1e-5 m/s
# plot
plot(seq(1,100), Qf, type="l", xlab="Time [days]", ylab="Qf, Streamflow Depletion Fraction")
