Explanations:The Mahanadi is a significant river in eastern India, primarily flowing through the states of Chhattisgarh and Odisha. The river's origin and course are important geographical facts that are often tested in competitive examinations. Let's delve into the details of the Mahanadi river and its drainage basin.
The Mahanadi originates in the highlands of Chhattisgarh, specifically near the village of Sihawa in Raipur district. This is a well-established geographical fact and is the correct part of the first statement. The river then flows eastward through the state of Odisha, eventually emptying into the Bay of Bengal. The river's course does not pass through Andhra Pradesh, which makes the second statement incorrect.
The drainage basin of the Mahanadi is the area of land where water from rain or snow drains into the river. The basin covers parts of both Chhattisgarh and Odisha. However, the specific percentage of the drainage basin that lies in Odisha is not fifty-three percent, as stated in the third statement. The actual percentage is closer to sixty percent, with the remaining forty percent in Chhattisgarh. This makes the third statement incorrect as well.
Understanding the origin, course, and drainage basin of the Mahanadi is crucial for geographical knowledge. The river plays a significant role in the hydrology and agriculture of the region, and its management is a topic of interest for environmental and economic studies. The correct answer to the question is that only the first statement is true, as the Mahanadi does indeed rise near Sihawa in Raipur district of Chhattisgarh.
