Ajay River

Ajay River originates on a small hill which is about 300 meters high, south west of Munger in the state of Bihar. Then it flows through Jharkhand and enters West Bengal at Simjuri, near Chittaranjan. This river also forms the border between Bardhaman District and Jharkhand and then between Birbhum District and Bardhaman District, and finally it enters Katwa subdivision of Bardhaman district at Nareng village in Ketugram police station. It then goes on to join the Bhagirathi River at Katwa Town. Total length of the Ajay is 288 km, out of which 152 km is in West Bengal. The catchment area of Ajay River is 6,000 km2.
Some of the significant tributaries of Ajay are Pathro and Jayanti in Jharkhand, and Tumuni and Kunur in Bardhaman district of West Bengal. The upper reach of the river pass through hilly regions with laterite soil. It is only from Ausgram in Bardhaman district that the Ajay flows through alluvial plains. The Ajay valley was densely forested with sal, piyasal and palas trees till recent times when mining and other activities led to the clearing of forests.The Ajay is an ephemeral, monsoon inCuenced river, originated from the Chhotanagpur plateau at Batpar
of Jamui, Bihar, Cowing through heterogeneous lithology and merge with the river Bhagirathi in West
Bengal. Here, an attempt has been made to study the directional relationship between paleo-Cow and the
present Cow direction of the Ajay river in West Bengal. Paleocurrent data help to reconstruct the details
of paleo-Cuvial system, especially the sedimentary environment of the past. The present work was carried
out on the basis of detailed Beld work at different river segments. In this work, paleo-directional data were
obtained from the primary sedimentary structure. Present Cow direction data were collected using Coats,
microform developed on active channel bed and also from sediment grain orientation. By using collected
directional data, vector mean of paleo and present Cow direction were computed. Analytical results reveal
that difference is minimum between present and paleo Cow direction in studied segments. The directional
relationship between the paleo and the present Cow direction was divergent in two segments, convergent
in four segments and parallel in three segments. The results help us to understand the sedimentary
environment and changing Cow regimes of the studied segments.
History of Ajay River
In many researches about the history of ancient India it has been found that the river called Amystis that flows past a town called Katadupa, in the days of Megasthenes. However, there is another historian Wilfred opines that Amystis is modern day Ajay. In the recent times there has been numerous investigation regarding the remains of ancient civilization similar to Indus Valley Civilizationat Pandu Rajar Dhibi in the lower Ajay valley.
The Ajay River originates on a small hill about 300 metres high, southwest of Munger in Bihar. It then flows through Jharkhand and enters West Bengal at Simjuri, near Chittaranjan. It first forms the border between Bardhaman District and Jharkhand and then between Bardhaman District and Birbhum District, and finally it enters Katwa subdivision of Bardhaman district at Nareng village in Ketugram police station. It then joins the Bhagirathi River at Katwa Town.
As per government records there have been 14 floods recorded in the 20th century in the Ajay River. In order to prevent flooding the lower reaches of the river have embankments.
Jaydev Kenduli, claimed to be the birth place of the 13th century Sanskrit poet Jayadeva of Geeta Govinda fame, and Churulia, birth place of Kazi Nazrul Islam are located on the banks of the Ajay.(@পরিবেশ ও বাংলার নদী)
