draw the phreatic lines

Question

Accepted Answer

Phreatic lines are lines that represent the water table in an aquifer.

Phreatic lines are used to understand the groundwater flow and the level of saturation in an aquifer.
They are typically drawn as contour lines on a map, connecting points of equal groundwater elevation.
Phreatic lines can help identify areas of recharge and discharge, as well as potential groundwater contamination.
For example, if a phreatic line intersects a river, it indicates that the river is recharging the aquifer.
Phreatic lines can also be used to determine the direction of groundwater flow, as they generally slope downhill.
Understanding phreatic lines is important in managing water resources and designing wells and groundwater extraction systems.
