5. GELOGICAL SETUP 
The geological formations in the district are represented by 
Quaternary deposits of Indo-Gangetic Plains (area covered- 
94.16%) and Tertiary rocks of Middle Siwalik Group (5.84). 
The Quaternary deposits range in age from Pleistocene to 
Recent period. Their thickness varies from a few meters to 
about 1200 meters. The Quaternary deposits have been 
classified into the newer alluvium of Pleistocene period known 
as Bhangar (with associated gravel talus known as Bhabhar) 
and older alluvium known as Khaddar. The Bhangar comprises 
6. HYDROGEOMORPHOLOGY 
Hydrogeomorphological mapping by using high spatial 
resolution satellite images has emerged as a powerful tool for 
delineating ground water prospect zones, specially in the 
regions comprising fluvial / denudational and structural 
geomorphic units. The area under investigation is characterized 
by three main geomorphic units viz. NW-SE trending mountain 
ranges, piedmont zone and alluvial plain. 
The Hydrogeomorphological interpretation in the area was 
carried out on 1:50,000 scale using Indian Remote Sensing 
(IRS) 1C, False Colour Composite (FCC) imageries (February 
& October 2000) and Survey of India topographical sheet (53 
B/13,14,15 & 53 F/1,2,3). 
Based on image characteristics of landforms (tone, texture, 
drainage, size, association etc.), their genesis, occurrence and 
composition, the various hydrogeomorphic units in the area 
were classified into forms of fluvial origin and denudational 
origin. The village level information collected for ground water 
recharge, depth to Water table, water table fluctuation and 
501 
of stream laid silt, sand, clay and calcareous nodules, 
comparatively occupies the higher terrain, whereas the Khaddar 
comprising of poorly sorted silt, sand, gravel and clay occurs 
adjacent to the river channels. The Bhabhar occupies the outer 
margins of the Siwaliks. The rocks of Middle Siwalik group are 
exposed in the northernmost parts of Yamunanagar district in a 
2 to 8 km wide zone. It is marked by alternating sequence of 
massive sandstone, red shales, clay and occasional pebbly beds. 
quality of water coupled with interpretation of satellite images 
helped in the final preparation of hydrogeomorphological map. 
Geomorphic landforms in Yamunanagar district are dominated 
by forms of fluvial origin covering about 80% of the district 
area. The denudational landforms accounting for 12% of the 
area occupy the northeastern parts of the district in the Siwalik 
hill region. An area of about 140 sq. km. (8%) is occupied by 
rivers and water bodies (Table 2). 
6.1 Forms of fluvial origin: Alluvial plain and flood plain 
constitutes the main forms of fluvial origin in addition to 
Palaeochannel, channel bars and valley fills. These are 
characterized by very gentle sloping, thick deposits of river 
alluvium mainly pebbles, cobbles, boulders, sand, silt and 
clays. These units form the main source of ground water in the 
region. The alluvial plain extends south of piedmont zone 
occupying elevation of 300 to 350 m above msl. They have a 
southwestward slope with an average gradient of 1.5m /km. 
Units of fluvial origin covers 80.2596 (1428.02 sq. km.) area of 
the district which belongs to alluvial plain [(deep/shallow) 
(74.31%)] and flood plain [(deep/shallow) (5.78%)] units.
