WebT = 2.3Q/2π ∆s r … (5.52) The computed value of T and other known data for the observation well are substituted in Eq. (5.48) and the distance of the pumped well from the recharge boundary a is determined. Since the drawdowns are affected by recharge, the storage coefficient S cannot be computed from the distance-drawdown field data graph. WebDec 11, 2000 · When the groundwater system has adjusted to the pumping, the resulting pattern of water table depression is sometimes referred to as steady-state drawdown; this feature is illustrated in figure 1. The pattern of water table distortion is called the cone of depression , and the area over which the depression can be detected is called the …
