Distance drawdown curve
WebTheis developed a standard type curve which relates the theoretical response of an aquifer to pumping. The type curve is obtained by plotting W(u) (the well function of u) vs. 1/u … Webthe drawdown curve is as predicted by the Theis equation When the cone reaches the boundary this is the last moment that the drawdown curve will be as predicted by the Theis equation. Note drawdown equals drawup thus the head has not changed at the boundary. When the cone is beyond the boundary drawdown is calculated by summing the solutions

WebJul 25, 1984 · Distance-drawdown readings can also be analysed in the same way, and the overlay can be used to determine the time-drawdown curve for a known set of aquifer parameters. A single time-drawdown point can produce one aquifer characteristic if an assumption of the other characteristic is made. WebAug 14, 2024 · Because the distance from the pumping well to the sea boundary is approximately four times of the radius of influence, seaside boundary effect on the drawdown curve can be neglected. Therefore, mirrored drawdown curve of the seaside about the vertical axis through the pumping well (black color dash line in Fig. 7 ) should …

Thus, using distance drawdown curve, the radius of influence (R) at a ...
WebThe residual drawdown s’ at any point located at a distance r from the well is obtained using the relationship. The Drawdown curves during pumping and recovery are shown in Fig 7.13. The above approach assumes equal values of storage coefficient both before and after pumping. In practice S’ may be smaller than S due to imperfect elastic ...
