Wells are defined by the coordinates of the center of the well, a pumping rate, and a well radius. A positive pumping rate indicates production and a negative rate indicates injection. The recharge is distributed over the entire infinite plane of the model. An ellipse defines the shape and position of the water-table mound created if there is no regional gradient. The recharge rate should be a positive value.
Ponds are circular recharge or discharge areas.
Ponds are defined in a manner similar to wells. The coordinates of the center of the pond are given along with the radius of the pond. A positive rate indicates infiltration and negative indicates discharge from the aquifer. Linesinks are linear recharge or discharge features. After defining all aquifer properties and analytic elements, you run WinFlow by selecting Calc from the main menu and Recalculate from the pull-down menu.
