wtConfigurePumpwell: Pumped well parameter values

In KWB-R/kwb.wtaq: Interface to WTAQ Drawdown Model (http://water.usgs.gov/ogw/wtaq/)

Pumped well parameter values

Description

Define WTAQ parameters related to the pumped well

Usage

wtConfigurePumpwell(ipws = 0, ipwd = 1, rw = 1, rc = ifelse(ipwd == 


    0, 0, rw), zpd = 5, zpl = 10, sw = 0, qq = 0.05, tspw = data.frame(t = 60 * 


    1:3, dd = 2 * c(0.4, 0.6, 0.7)), pwname = "PW", ipump = 1, 


    irun = 1)

Arguments

ipws	Type of pumped well: IPWS = 0: Partially penetrating pumped well. IPWS = 1: Fully penetrating pumped well. Default: 0
ipwd	Type of diameter of pumped well: IPWD = 0: Infinitesimal diameter (line-source theory). IPWD = 1: Finite diameter. Default: 1
rw	Radius of pumped well screen, in units of length. Default: 1.0
rc	Inside radius of pumped well in the interval where water levels are changing during pumping, in units of length. Must be 0 if IPWD = 0. Default: value of rw, but 0 if ipwd = 0.
zpd	Depth below top of aquifer or initial water table to the top of the screened interval of the pumped well, in units of length. Default: 5.0
zpl	Depth below top of aquifer or initial water table to the bottom of the screened interval of the pumped well, in units of length. Default: 10.0
sw	Well-bore skin parameter, dimensionless. Default: 0.0
qq	Pumping rate of well, in units of cubic length per time. Default: 0.05
tspw	data.frame with column t containing the user-specified times for which drawdown at the pumped well will be calculated. If the data.frame has no rows, no drawdowns are calculated for the pumped well. The data.frame can (optionally) contain the drawdowns that have been measured for the pumped well at the corresponding times in an additional column dd.
pwname	Name of pumping well. This parameter is not evaluated by WTAQ but will be used in the result data frame returned by wtRunConfiguration. We introduce it in order to be able to identify the well within a wellfield. Default: "PW"
ipump	Option to suppress calculations of drawdown at pumped well: IPUMP = 0: Drawdown is not calculated at pumped well. IPUMP = 1: Drawdown is calculated at pumped well.
irun	Option to suppress drawdown calculations for the pumped well. Allows user to specify time-drawdown data, but those data are ignored during the simulation. Options are: IRUN = 0: Drawdowns not calculated. IRUN = 1: Drawdowns calculated.

Value

list with elements irun, ipws, ipwd, ipump,

qq, rw, rc, zpd, zpl, sw,

tspw, representing WTAQ parameters related to the pumped well. See
