streamDepletr is an R package with functions for assessing the impacts of groundwater pumping on streams. There are two primary categories of functions:
- Analytical streamflow depletion models, which estimate the change in
groundwater inputs to a stream resulting from pumping (
hunt,glover,hantush,intermittent_pumping) - Depletion apportionment equations, which distribute streamflow
depletion estimating using the analytical models to different
reaches within a stream network (
apportion_inverse,apportion_web,apportion_polygon,apportion_wedge) - Data preparation functions to prepare inputs for the analytical
models and depletion apportionment equations
(
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 fractionQf<- glover(t= seq(1,100), # timesteps to evaluated=150, # well to stream distanceS=0.10, # specific yieldTr=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")
