The Dhandhar River is a monsoon river that only flows during the monsoon season. It has relatively little water in the winter, whereas the volume of water grows in the summer. It originates in Jamnagar's Lalpur district. The primary fluvial sedimentary facies of the Late Pleistocene deposits in the Dhadhar River basin have preserved signs of palaeo-drainage and may act as an essential connection between the sub-humid Narmada basin in the south and the semi-arid Mahi basin in the north. This article will explain to you about the Dhandhar river which will be helpful in Geography preparation for the UPSC Civil service exam.

Dhandhar river

• The Dhadhar river is one of Gujarat's west-flowing rivers.
• It rises in Gujarat's Pavagadh Hills and runs through the districts of Vadodara and Bharuch.
• After 87 kilometers, the river Dhadhar gets the Vishwamitri tributary from the right bank near the Pingalwara hamlet.
• The river runs for around 142 kilometers from its headwaters to its mouth in the Gulf of Khambhat.
• Vishwamitri, Jambuo, Dev, and Surya rivers are significant tributaries of the Dhadhar river.
• The majority of the basin has a tropical wet climate, which is mostly attributable to the presence of the Western Ghats.
• Due to the relatively high elevation of forest land, the portion of the basin near the river's origin has a milder climate.
• The southwest monsoon has the most impact on rainfall. The impact is particularly noticeable in Vadodara, which is on the windward side of the Western Ghats.
• The Dhadhar River basin has maintained indications of palaeo-drainage and might act as a vital connection between the sub-humid Narmada basin in the south and the semi-arid Mahi basin in the north.
• Overbank fines coupled with crevasse splays are among the sedimentary facies recorded.
• Fine-grained overbank sediments are thought to have been produced during the flood stage by sheet flow of sediments over the banks of small distributary channels.

GS Mains Questions and Model Answers

Q1: Explain the significance of smaller rivers like Dhandhar in western India’s geography and economy.

Answer: Smaller rivers such as Dhandhar play an essential role in the geography and economy of western India. Geographically, these rivers originate in the Himalayan region or other elevated terrains and flow westward, eventually draining into the Arabian Sea. Their relatively smaller size and shorter course distinguish them from the larger rivers in India, such as the Ganges and Brahmaputra.

• Organized Debate and Decision-Making: Parliamentary Groups ensure that party members can collectively debate and decide on matters of national importance, presenting a unified voice in legislative discussions.
• Representation of the People: Each Parliamentary Group represents the interests of the people through their elected members, acting as the voice of various constituencies and communities in Parliament.
• Policy Influence: These groups influence national policies by debating bills, proposing amendments, and shaping the legislative agenda.
• Checks and Balances: The Opposition Parliamentary Groups play a crucial role in scrutinizing the government, ensuring accountability and transparency in the legislative process.
• Coordination: Parliamentary Groups coordinate party activities in Parliament, ensuring smooth operation and effective representation of party views.

In conclusion, Parliamentary Groups are essential in maintaining the democratic process by ensuring that party and coalition views are articulated and legislative functions proceed efficiently.

Q2: Discuss the environmental challenges faced by smaller rivers like Dhandhar and their impact on the surrounding region.

Answer: Smaller rivers such as Dhandhar face several environmental challenges that affect both their flow and the ecosystem they support. The primary issue is pollution, caused by untreated industrial waste, agricultural runoff, and urban sewage. This contamination degrades water quality, making it unsuitable for both human consumption and agricultural use.

• Pollution and Urbanization: Pollution from industries, agriculture, and urban development is a significant challenge for Dhandhar rivers, affecting water quality and flow.
• Climate Change: Climate change-induced irregular rainfall patterns result in fluctuations in river water levels, with some rivers running dry during certain seasons, leading to water shortages.
• Deforestation: Deforestation and urbanization reduce the natural water recharge capabilities of these rivers, threatening their flow.

Together, these environmental challenges significantly affect the sustainability and utility of these rivers for agriculture and local communities.

Q3: Analyze the role of smaller rivers like Dhandhar in the agricultural landscape of western India.

Answer: Smaller rivers like Dhandhar play a pivotal role in sustaining the agricultural landscape of western India. These rivers provide critical water resources for irrigation, which is vital for the region’s predominantly agrarian economy. The rivers’ water is used to irrigate crops such as cotton, groundnut, rice, and wheat, all of which are central to the economy of states like Gujarat, Maharashtra, and Rajasthan.

• Water for Irrigation: The rivers provide essential irrigation for water-intensive crops such as rice, cotton, and groundnut.
• Soil Fertility: These rivers help maintain soil fertility by providing nutrient-rich water to the agricultural lands.
• Vulnerability to Water Scarcity: The reliance on these smaller rivers makes the region vulnerable to water scarcity during dry spells or when the rivers’ flow is reduced.

Efficient water management practices are necessary to mitigate the risks related to water availability and ensure the long-term viability of agriculture in these regions.

Previous Year Questions on Dhandhar

1. UPSC CSE 2023

Question: What are the challenges faced by smaller rivers in India and their impact on the agricultural sector?

Answer: Smaller rivers in India face several challenges such as pollution, encroachment, and reduced water flow due to deforestation and climate change. These issues affect the agricultural sector by reducing water availability for irrigation, which is crucial for crops like rice, cotton, and groundnut. Reduced water levels can lead to crop failures, food insecurity, and economic losses in regions dependent on these rivers for farming.

2. UPSC CSE 2022

Question: Discuss the role of rivers in shaping the economy of western India, with special emphasis on the smaller rivers like Dhandhar.
