The Web-Based STRMDEPL08 evaluates four analytical solutions that simulate streamflow depletion by a nearby pumping well. It is based on STRMDEPL08 (Reeves, 2008) and the earlier STRMDEPL (Barlow, 2000). These two earlier programs are written in Fortran, require text input files, and produce tabular output. The web-based version was written to provide an easier interface to the analytical solutions with more convenient units and simplified output. (View more...)

Units used

  • ft: foot
  • ft2/day: square foot per day
  • gpm: gallons per minute
  • ft/day: foot per day
  • Note, 1 cubic foot per second = 448.8 gallons per minute

Storage Coefficient:  
Specific Yield of Aquitard:  
Hydraulic Conductivity of  Aquitard (ft/day):  
Stream Width (ft):  
Thickness of Aquitard (ft):  
Distance from Streambed  
to Bottom of Aquitard (ft):

For analysis of intermittent pumping, the stand-alone executable STRMDEPL08 is recommended. First, populate the requred fields above, then click the button to the right to generate the text for the input file required by STRMDEPL08. The daily series of input pumping rates must be added by the user. See the STRMDEPL08 documentation (Appendix 1) for details on the input file. (After choosing this option, please reload this page to allow other options to be submitted.)
