Which one of the following rivers has the highest replenishable ground...
The correct answer is option 'C', the Ganga river.
Explanation:
Replenishable groundwater resource refers to the amount of water that can be naturally replenished and sustained over time. It is an important measure of the availability and sustainability of groundwater in a particular region.
The Ganga river, also known as the Ganges, is the river with the highest replenishable groundwater resource in the country. Here's why:
1. Geographical Factors:
- The Ganga river basin is one of the largest in India, covering a significant portion of the northern and eastern parts of the country.
- The basin includes areas with diverse topography, including the Himalayas, the Gangetic plains, and the delta region, which contribute to the availability of groundwater.
2. Rainfall and Snowmelt:
- The Ganga basin receives substantial rainfall, especially during the monsoon season, which contributes to the recharge of groundwater.
- Additionally, the basin also receives water from snowmelt in the Himalayas, further adding to the replenishable groundwater resource.
3. Percolation and Infiltration:
- The Ganga river basin has a network of tributaries, canals, and distributaries, which facilitate the percolation and infiltration of water into the ground.
- The soil composition and permeability in the basin also play a crucial role in allowing water to seep into the aquifers and recharge the groundwater.
4. Aquifer Storage and Recharge:
- The Ganga basin consists of several aquifers that act as natural storage units for groundwater.
- The river and its tributaries provide a continuous flow of water, allowing for the recharge of these aquifers and maintaining a high replenishable groundwater resource.
5. Cultural and Religious Significance:
- The Ganga river holds immense cultural and religious significance in India, leading to a high level of public awareness and conservation efforts.
- The government and various organizations have taken initiatives to protect and restore the river, ensuring the sustainability of the groundwater resource.
In conclusion, the Ganga river has the highest replenishable groundwater resource in the country due to factors such as its geographical extent, rainfall, snowmelt, percolation, aquifer storage, and cultural significance.
