Regional flow in the aquifer was allowed to take different directions relative to the stream axis. Two critical pumping rates, Q C1 and Q C2, produce three capture-zone pattern scenarios: (1) at low pumping rates (Q < Q C1) water is solely withdrawn from the aquifer and no water from the stream enters the aquifer, (2) at medium pumping rates (Q C1 < Q < Q C2) a portion of stream water enters the aquifer but it is not captured by the well, and (3) at high pumping rates (Q > Q C2) pumped water is supplied from both the aquifer and the stream with different proportions. For the second and third scenarios, the stream length interval through which stream water enters the aquifer was determined and found to be more sensitive to pumping rate as the regional flow direction approaches the stream axis. The portion of pumped water supplied by the stream was determined in the third scenario. Finally, the capture-zone asymmetry with respect to its axial line was delineated.
