Abstract

Water table contour lines (or flow lines) are similar to topographic lines on a map. They essentially represent "elevations" in the subsurface. These elevations are known as the hydraulic head. Water table contour lines can be used to tell which way groundwater will flow in a given region. Lots of wells are drilled and the hydraulic head is measured in each one. Water table contours are drawn that join areas of the equal head. These water table contours lines are also called equipotential lines. The map of contour lines is called a flow net. Groundwater always moves from an area of the higher hydraulic head to an area of the lower hydraulic head, and perpendicular to equipotential lines. In our project, we implement the concept of water table contour map and hydrological studies on Erode district using GIS software which plays a vital role in the latest technology.
