Watershed development refers to the conservation, regeneration and the judicious use of all the natural resources such as land, water, plants, animals, etc., within a particular watershed. Watershed management tries to bring about the best possible balance in the environment between natural resources on the one side, and human on the other. Attempts to overcome problem of soil degradation on large tracts of cultivable land in a watershed are being made through large investments in watershed management.
The World Bank assisted Karnataka Watershed Development Project, KWDP -II, popularly known as SUJALA project has been implemented in following districts of Karnataka state viz., Bidar, Kalaburgi, Yadgiri, Koppal, Gadag, Davanagere, Chamarajanagar, Tumkuru, Vijayapura, Raichur and Chikkamagaluru in selected 931 micro-watersheds (Batch 4,5,6 of IWMP) covering an area of 4,46,954 ha.
The UAHS, Shivamogga is involved in Chikamagaluru and Davanagere district under the KWDP-II, SUJALA-III project covering Tarikere, Kadur, Channagiri and Chikkamagaluru taluks comprising of 200 micro watersheds over an area of 1,20,278.81 ha.SUJALA-III project locations of UAHS, Shivamogga

Chikkamagaluru is situated in the Mallenadu region of Karnataka in the Deccan plateau in the foothills of the Western Ghats. It lies in the south central part of Karnataka, between 12° 54′42″ - 13° 53′ 53″ N latitudes and 75° 04′ 46″ - 76° 21′ 50″ E longitudes, with a geographical area of 7201 km2. The district receives normal average rainfall of 1925 mm. 30 per cent of the district (2108.62 km²) is covered with forests. According to 2011 census, Chikkamagaluru had a population of 118,496 within that males constitute 51 per cent of the population and females 49 per cent.

Chikkamagaluru district falls in Krishna basin and is the birth place of six rivers like Thunga, Bhadra, Hemavathi, Vedavathi, Yagachi and Netravathi. District comprises of 7 taluks namely, Kadur, Mudigere, Chikmagalur, Koppa, Tarikere, Sringeri and N. R. Pura. Nearly 50 per cent of the area in Tarikere taluk is covered by gneiss and rest of the area is occupied by schist formation. About 41 per cent of the geographical area of the district is under cultivation. Irrigation through dug wells and shallow tube wells is more prevalent. Major Agricultural crops cultivated in the district are paddy, jowar, ragi, pulses, sunflower, groundnut and Horticultural crops like coffee, coconut and arecanut.
It is located at 13.72°N 75.82°E. It has an average elevation of 698 metres (2290 feet). Agriculture is the primary occupation here. Betelnut, Paddy, Ragi, Arecanut, Coffee, Coconut, Banana, Pan leaves, Mango and Corn are the major cash crops grown in this region. The region was formerly a major rice producing area which have been largely replaced by arecanut.
It is located at 13.553345°N 76.011260°E. It has an average elevation of 763 metres (2503 feet). The larger portion of the taluk consists of the Malnad or hill country, which contains some of the wildest mountain scenery in southern India. The stable crop is rice, chiefly grown on the hifi slopes, where the natural rainfall is sufficient, or in the river valley, where the fields can be irrigated.
Davanagere is a city in the centre of the southern Indian state of Karnataka. Hitherto being a cotton hub and hence popularly known before as the Manchester of Karnataka, the commercial ventures of the city is now dominated by education and agro-processing industries. Davanagere became a separate district in 1997, when it was separated from the erstwhile undivided district of Chitradurga for administration conveniences.
The Davanagere district enjoys semi arid climate, dryness in the major part of the year and temperature varies from 19º to 39º C. In general, southwest monsoon contributes 58 % of total rainfall and northeast monsoon contributes 22 % rainfall. The remaining 20 % rainfall is received as sporadic rains in summer months. It receives low to moderate rainfall. Normal annual rainfall varies between 556 mm in Jagalur and 808 mm in Channagiri taluk.
Davanagere district forms part of the southern maidan having extensively undulating plateau with elevations ranging from 600 to 1000m. Thungabhadra and chinna Hagari rivers drain Davanagere district. Part of the district covering Jagalur, Harihar,Harappanahalli, and Davanagere taluks are grouped under the central dry zone and Honnali and Channagiri taluks in the southern transition zone of Karnataka.
The geological formations in Davanagere district placed under Dharwar type of schist belts. Based on the path of deposition, the Dharwarian schist belt is mainly classified into Kudremukli belt, Bababudan belt, Shimoga belt, Chitradurga belt and Sandur belt. The southeast part of the Shimoga belt traversed the Davanagere district from northwest (Honnali) to southwest (Channagiri) direction. This belt forms the main extent of the schistose rocks with exposed Islands of basement gneissic complex at Honnali and Channagiri region.
Physiographically of the area has been broadly divided into two landscapes based on geology. They are Schist and gneiss. Based on slope and its relief features, the area has been further subdivided into four landforms, viz; mounds/ridges, summits, side slopes and very gently sloping uplands.
Channagiri is a panchayat town in Davanagere district in the state of Karnataka, India. Channagiri is located at 14.03°N 75.93°E. It has an average elevation of 662 metres (2171 feet). The city has multiethnic population.
