2.1 Chenab River System and Basin Characteristics

The Chenab river is formed after the two streams namely the Chandra and the Bhaga

merge together near Tandi about 6 km. South of Keylong, the district headquarter of

Lahaul and Spiti of Himachal Pradesh. The Chandra and the Bhaga originates at about

5412 m and 4891 m from the north and south faces of Baralcha Pass respectively in

Himalayan canton of Lahaul Spiti valley. The total lengths of the Chandra and the Bhaga

upto their confluence is about 125 km and 80 km respectively. The combine river, known

as the Chenab or Chandrabhaga flows in a North-Westerly direction for about 48 km.

where it is joined by its biggest tributary , the Miyar-Nallah on the right bank. Thereafter,

it flows for about 96 km generally in northerly direction in Himachal Pradesh and crosses

the Pangi Valley before entering in to Paddar area of Doda district of Jammu and Kashmir

state .The river flows in a North-West direction for about 61 km where it is joined by a

tributary , the Marusudar on right bank near Bhandarkot . Further downstream, the river

flows in a southerly direction for about 32 km upto Thathri where it takes a West- ward

turn. In this reach , about 15 km downstream of Thathri, Niru nallahs joins the Chenab on

its left bank. The river Chenab there after flows generally in North-West direction for

another 41 km till it receives a tributary Bichlery on the right bank. Afterwards the river

traverses in Westerly direction for a distance of about 64 km. In this reach a number of

small streams namely Chenani, Talsuen, Yani , Ans etc join the right bank and Katu nallahs

, Mandial ,Painthal khud join the left bank. Downstream of Ans river confluence the river

changes its direction and flows in southerly course for about 55 km up to Akhnoor. There

after , it enters into Sialkot district of Pakistan. Total length of river from confluence of

Chandra and Bhaga is about 410 km.

The Chenab basin in India is spread over the two states, Himachal Pradesh and Jammu &

Kashmir which comprises the extreme western sector of Himalayas. Upper catchment lies

in Lahaul area and Pangi tahsil of Chamba district of Himachal Pradesh. This region is

roughly in rectangular shape with main Himalayas on the north, mid Himalayas on south

and the connecting lines of heights at either ends on east and west respectively. The

Chenab basin in Jammu & Kashmir lies in its southern part covering sixdistricts of Doda,

Udhampur , Kishtwar, Jammu and Rajouri. This region of state is called Jammu region. The

drainage basin covers the area partly between Shivaliks and outer Himalayas and partly

between outer and central Himalayas. The total catchment area of the basin within India

is about 29050 Sq. Km, out of which about 21206 Sq.km lies in Jammu region of J & K state

and about 7844 Sq km lies in Himachal Pradesh. The drainage area of Chenab River up to

dam site of Kirthai –I H E Project is 8530 Sq km, out of which 4608 Sq km is snow fed and

rest 3922 Sq km is rain fed.

5.0 GEOLOGY

5.1 Regional Geology

Catchment area of the river Chenab is generally narrow and elongated up to the middle

reach after which it widens in to fan shape. Total catchment area within the boundary of

India is about 29050 Sq km and stretches across Himachal Pradesh and Jammu and

Kashmir up to international boundary between India and Pakistan through the

formations belonging to different geological ages ranging from Palaeozoic to quaternary.

In the upper reaches Kirol , Chai , Granite and gneiss rocks are generally encountered. In

middle reaches and also in upper reaches to some extent formations of phyllites ,

quartzite , gneissic schist and dogra slates with gypsum and crystalline limestone bands

are found. In the lower reaches the river traverses through the formations belonging to

Sirban lime stones ,Eocnes and Lower Murries.

5.2 Seismicity

Designed has to be carried according to relevant Indian Standards—latest edition. The dam is

situated in close vicinity (less than 5 km ) of Main Central Thrust ( MCT ) which is interpreted to be

seismically active. In addition, the site is located between Zanskar thrust towards north ( 125 km )

and Panjal Thrust towards south ( 65 km ). Further, a number of major thrust / lineaments are

disposed within 200 km radius of the dam site. These include the Indus Suture Zone , Shyok Sature

Zone , Murre Thrust , Digdani Thrust Main Boundary Fault (MBF) etc.

A review of recorded Seismic activities shows that Bhaderwah Earthquake ( 1955 )magnitude 7.5

lies about 30 km south of the site of dam. The area around the site also keeps on experiencing

earth quakes of low to moderate intensities. The area must have experienced the earthquake

(1905) which had its epicenter in Kangra.

5.3 Geology of Project Area



The proposed dam axis is located at about 275 m upstream of the bailey bridge across

river Chenab in a valley with steep slopes. Large scale geological mapping in and

around the dam site , covering about 0.53 sq. Km area on 1:2000 scale has been done.

This reveals that the project area is represented by rocks of Quartz-mica-schist

belonging to Salkhala group. These rocks are thinly foliated and intersected by joints.

The strike of foliation plane varies from N 40° E- S 40° W to N 20° E- S 20° W with 35° -

40° dip due south east i.e. towards upstream side. The area upstream of the dam axis

to a distance of 600 m is marked by the presence of inner foliated marble bands. The

quartz mica schist is exposed on both the abutments. A thin cover of overburden

conceals the bed rock at few places.

The HRT lies entirely in quartz – mica – schist formation.

The underground power house which is located in the left side of the hill is represented

by quartz-mica-schist rock. The rock is thinly foliated and fairly jointed. The rocks are

rated fair to good.

6.0 CLIMATE AND WORKING PERIOD

The basin receives precipitation round the year. During Dec. to May precipitation is

mostly in the form of snow except in May when snowfall is confined to higher altitudes and

during July to October the precipitation is due to monsoon activity. June and November are

the months of least precipitation. Mean annual precipitation over the basin up to Kirthai

dam is 750 mm. The area has recorded minimum temperature of -2.40C and maximum

temperature of 380C.

7.0 CONSTRUCTION SCHEDULE

Completion time for all construction activities for the project as a whole i.e.

commissioning of all the units is 60 months.

8.0 STATUS OF INFRASTRUCTURE AND CONSTRUCTION FACILITIES
