Water Contour :

Contours are drawn on the maps to show up and down on the earth. Similar to show water level under ground, water contours can be drawn. Land Contour remains unchanged over the years but water contour change with the season. In rainy season water level comes upwards and in summer it goes down.


Ground water Flow: Flow of ground water and flow of electricity have lot of similarity.

Ground water Flow Flow of Electricity

Flow due to difference in water level Flow due to difference in voltage

Flow depends on permeability of land flow depends on electric conductivity

Level difference Current (Flow) =------------------- Same law is applicable to electricity Land resistance

Area of pore  Flow - proportional.
