Question

To evaluate the different effect on indian river system by the considering the diversified

physical condition of India ? ​

Answer 1

Answer:

The strong wet and dry seasons of tropical monsoon hydrology in India necessitate development of storage and flow diversion schemes for utilization of water to meet various social and economic needs. However, the river valley schemes may cause adverse flow-related impacts due to storage, flow diversion, tunnelling and spoil disposal. There may be critical reaches in which altered flows are not able to sustain the river channel ecology and riparian environment that existed prior to implementation of the storage and diversion schemes. In the past, environmental flows in India have usually been understood as the minimum flow to be released downstream from a dam as compensation for riparian rights, without considering the impacts on the river ecosystem. Rivers in India have been significantly influenced by anthropogenic activities over the past 60 years and have great social and religious significance to the vast population. This paper explores various aspects of past, present and future environmental flow assessment (EFA) in India highlighted by case studies from rivers across the nation. It demonstrates that multidisciplinary studies requiring expertise from a range of fields are needed for EFA, and that environmental flows are necessary for aquatic ecosystems to remain in a healthy state and for the sustainable use of water resources. The major focus areas for the development of EFA research in India are the creation of a shareable database for hydrological, ecological and socioeconomic data, developing hydrology–ecology relationships, evaluation of ecosystem services, addressing pollution due to anthropogenic activities and promotion of research on EFA. At the same time, efforts will be needed to develop new methods or refine existing methods for India.

Answer 2

The indian river system is diversified  due to physical characteristics of Indian landmass.

Explanation:

• The Indian river system is divided into two parts as the peninsular and the Himalayas river system which are diversified on the basis of the physical conditions like the mountains, plateau, and plains.  

• The peninsular river is those that flow in the southern parts of the country are marked by the plateaus and then flows into the sea.

• The Himalayan rivers are those that originate in the Himalayan and flow throughout the year and form river deltas. They are separated by the north and south ranges of central India.  

• The plains are fertile lands were these rivers deposits most of the sediments that they have brought downstream by the erosion and Indian desert consists of the barren and dry land where rivers are short-lived.

• In the hilly states of the northeast, the rivers are heavy and travel large distances as this region gert most of the rainfall the rivers create erosion.
