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)
| 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 |
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
|
| 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. |
