Sentence examples for drawdowns are from inspiring English sources

An instantaneous pressure pulse is induced in the stress interval and resulting drawdowns are recorded in both the stress and the observation intervals.

Because the main drawdown flow periods (DD5, DD11, DD13 and DD18) are conducted slightly below the dew-point and for very short times, pressure drawdowns are governed by non-Darcy flow and mechanical skin only.

After a steady-state flow field is reached and the pumping rate and chamber drawdowns are measured, a tracer is released into the injection chamber, and the concentration breakthrough curve is recorded in the extraction chamber.

Drawdowns are defined by ( dd_{i,j,k,t} ) and are equal to the difference between an initial head at locations i, j, k at the end of stress period t, ( (h_{i,j,k,t} )^{^circ } ), and the head calculated at the location at the end of the stress period after implementation of the optimal management strategy,( h_{i,j,k,t} ): dd_{i,j,k,t} = (h_{i,j,k,t} )^{^circ } - h_{i,j,k,t} (2.2).

The sum of water levels from well UE-20n 1 and known drawdowns are herein referred to as "measured" water levels that represent both pumping and nonpumping stresses.

Past drawdowns were carried out in peacetime.

During these tests, drawdowns were monitored at different depths along several deep boreholes.

The measured and computed drawdowns were compared to evaluate the efficacy of the developed spreadsheet programs and matching of the observed time-drawdown and type curves by employing two performance criteria: correlation coefficient (R) and root mean square error (RMSE).

The actual transfer of funds, commonly referred to as "drawdowns", is usually done electronically by requesting the funds to the Federal agency via website or a network.

The reliability of differentiating drawdowns from environmental fluctuations with the drawdown estimation approach was tested by analytically simulating "measured" water levels where drawdowns were known (numerically simulated).

RMS errors of prediction for noiseless drawdowns were insignificant relative to drawdowns estimated from hypothetical "measured" water-level records.
