Sentence examples for to drawdown data from inspiring English sources

In the case illustrated, improved fits to drawdown data are obtained and the resultant transmissivities and storativities are found to be lower by 30% and an order of magnitude respectively, than estimates from classical methods.

Here we use our ME-based method to assimilate drawdown data recorded during cross-hole pumping tests in the heterogeneous alluvial Lauswiesen aquifer near Tübingen, Germany.

Then RTA plots and equations were used to analyze the pressure drawdown data, and PBA plots and equations were used to analyze the pressure buildup data.

The solution takes into account both the vertical anisotropy (azx = Kz/Kx) as well as the horizontal anisotropy (ayx = Ky/Kx) and has potential application areas to analyze pumping test drawdown data from partially-penetrating inclined wells by representing them as tiny parallelepiped as well as line sources.

Also the solution takes into account both the vertical anisotropy (azx = Kz/Kx) as well as the horizontal anisotropy (ayx = Ky/Kx) and has potential application areas to analyze pumping test drawdown data from partially-penetrating vertical and horizontal wells by representing them as tiny rectangular parallelepiped as well as line sources.

However, the useful life of the BFD reduces to just 276 years when drawdown data are considered; these data show reservoir use would be affected once 40% of storage was filled with sediment, with a 60% drawdown return period of 1 in 15 years.

Similar results were found when known drawdowns were added to measured environmental fluctuations from two alternative background wells to compute "measured" water levels and estimate drawdown (data not shown).

With this new solution, the horizontal anisotropy (ayx = Ky/Kx) in addition to the vertical anisotropy (azx = Kz/Kx) can also be determined using observed drawdown data.

However, drawdown data were collected at regular time intervals.

Analysis of pressure drawdown data from the simulation runs is shown in Fig. 5.

Second, we determine which parameterization is most adequate given the observed drawdown data.
