Sharavathi in Depth
Geology
The river basin mainly consists of Pre-Cambrian rocks. The two major groups of rocks found in the Sharavati river basin are the Dharwar Craton system and the peninsular gneiss.
The Dharwar Craton system: This system contains metamorphic rocks that are considered to be among the oldest in India. These rocks are derived from ancient sediments like conglomerates, ferruginous quartzites, greywackes, schists and limestones. They are rich in iron and manganese.
Peninsular gneiss: These are crystalline rocks and are made up of granite, granodiorite, granito-gneiss, migmatite etc.
Soils in the Sharavati basin are mainly lateritic in origin and tend to be acidic and reddish to brownish in colour. The various type of soil found here are clay loamy, clayey, clayey-skeletal, and loamy.
Climate
With a major part of the river lying in the Sahyadri mountains (Western Ghats), the Sharavati river basin receives a large amount of rainfall. Mean annual rainfall ranges from 6000 mm in the western side to 1700 mm in the eastern side of the basin. About 95% of the rainfall is received during the month of June to September (July being the rainiest) when the southwest monsoon is at its peak. There is some rainfall in the post monsoon season in the form of thundershowers mostly during October and some rainfall also occurs during the summer months of April and May.
During the morning, the relative humidity exceeds 75% for most times of the year. During the months of monsoon, the relative humidity during the afternoons is approximately 60%.
