Module ANS-IT . The module ANS-IT is used for forecast of drawdown in pumping and observation boreholes with various hydrogeological conditions
The module includes: • Forecast of drawdown in pumping and observation boreholes with various hydrogeological conditions and hydraulic boundaries of the I, II and III types; • Estimates of recommended pumping rate for aquifer tests to achieve target drawdowns in pumping and observation wells; • Selecting best locations for pumping and observation wells in plan and profile for successful hydraulic tests ; • Calculation of radius of influence for pumping wells; • Accounting for partial penetration of wells, well-bore storage and skin-effect; • Time-variable pumping rate; • Assessment of recommended pumping duration for best application of graphical matching methods; • Standard, semi-log or log-log plots for time-drawdown, distance-drawdown and combination plots; • Forecast and plots of water level recovery during a test; • Piezometric/drawdown maps and profiles; • Data export and import in EXCEL.
