Underground Water

Underground water is responsible for the following features:-

Springs – including hot springs and geysers.

It is a natural outflow of: water at or below the plane where the water table intersects hill- eide. It may flow strongly and even gush out with considerable force, or just ooze or seep out. It may be permanent or intermit- tent: (tmeporary). Where a Line of springs appears there is a. Spring Line.

Classification of springs accord- ing to the mode of formation: --** (Genetic Classification) Different types of springs are associated with different types of landforms. (1) Springs along, against or

across gullies in hilly areas. (see Fig. 1)

springs, a) Due to faulting, a porous rock layer iemak brought against an inpermeable layer. Where the water-table. and the porous rock layer. reaches the surface there occurs a spring. The depressed area is floored by impermeable rock and becomes a marsh, b) Where a system of jointing in a rook, e.g. Granite or limestone, reaches the surface aprings will occur, Water enters the Via the joints. c) An intrusion dyke divides a permeable layer of rock into two with their own separate water tables. Where the water tables outcrop, springs occur. (See Fig. 6a,b,c.)

Artisen Wells (See Fig. 9) - where the strata are arranged in a gently inclined downfold, foraing a shallow basin with the acquifer outeropping on the margins, cone ditions are particularly suitable for: the supnly of well-water. It sometimes happens that the acquifer 13 enclosed above and below by impermeable beds, while ite rim ie higher than the centre of the bar dri In this case, if a well is driven: through the overlying impermeable beds the water may rise under hyraulic pressure, near or actually to the surface. The former is know as 'semi-artisen well and needs pumping. The latter is an artison well. e.g. the London Basin is an artisen basin.
