The Brahmaputra is the fourth biggest river in the world in terms of annual discharge rate of about 19,830 cubic meter per second as its mouth and its catchments area is about 5, 80,000 sq.km located in the eastern Himalayan ranges and its neighbors that has occupied the area belonging to the four countries in percentage i.e. Tibetan Plateau of China (50.52%), India (33.62%), Bhutan (7.76%) and Bangladesh (8.10%). High order drainages of about 52 numbers of tributaries feed the Brahmaputra in the downstream side making it constant viable water resources in the region. Of these, the major 19 tributaries lie in the north bank while 12 others significant tributaries are in the south bank of the mighty river. In general, all total 15 numbers of principal tributaries lies in the Indian Territory. It may be worth mentioned that the Dihang (Siang), i.e. Tsangpo in the upper reaches and Subansiri contributes 37.40% and 10.66% surface run off to the Brahmaputra respectively. Moreover, the other two important tributories like Dibang (sikang) and Lohit contibutes around 7.65% and 9.50% surface runoff to the mighty river. Other tributaries such as Manas contributes water annually 6.75% (38,000 million cubic meters), Sonkosh contributes 3.18% (18,000 million cubic meters) and Burhidihing 2.65% (15,000 million cubic meters) annually to the Brahmaputra basin. Moreover, other important rivers are like Kopili, Jiabharali, Dudhnoi, Krishnai, Pagladia, Beki etc. The Northeast had a wonderful landscape with the broad Brahmaputra valley of Assam sandwiched by the Eastern Himalayas and Arakan Yuma ranges of hills. The Brahmaputra valley is the biggest in the region which has played an important role for the growth of the States and the regions economy. Mostly, Tsangpo contribution is very significant as concern to the recycling of water potentiality of Brahmaputra basin and its biodiversity apart from basins ecological balancing. Nevertheless, the river Brahmaputra is the sole identity of Assamese people flowing all along the state from east to west. The river Brahmaputra known as Tsangpo in the upper reaches, originates at an altitude of 5,300 meters from Kanglung Kung glacier located in southeastern part of Tibetan Plateau of China. After running for about 1700 km in the Tibetan Plateau the Tsangpo drains through the Tsangpo Gorge or Yarlung Zangbo Grand Canyon which is about a 2700 m deep, 240 km long canyon and finally it reaches the state of Arunachal Pradesh. The Brahmaputra being an international river, centre initiatives in association with the State Govt. can go long way in developing the region and in the country as a whole through proper planning and harnessing of available of water resource. The recent development on Chinas plan to divert water from the Tsangpo River to the worlds muddiest river, Huangho popularly known as the Yellow River appears to be a major threat to India. It has already reported by Indians National Remote Sensing Agency (NRSA) that China is constructing a Dam on its side of the Tsangpo River at Namcha Barwa located in the eastern plateau of Tibetan. The agency of National Remote Sensing is one of the agencies under the Indian Space Research Organization, Department of Space of India who has extracted information with the help of satellite images and its digital enhancement processes for Chinas planning to set up mega dam on Tsangpo. Though, India has not any plan to set up water resource project on Tsangpo yet Chinas plan is a serious matter to the whole northeast India as well as to the subcontinent and there is a possibility for furious disruption in planning of water resources management in the other rivers of the Brahmaputra basin in the forth coming days. Moreover, the India may not be aware of huge Tsangpos river characteristics, hydrological and morphological features due to the catchments falls in Tibet region. Therefore, Delhi may go for procuring all necessary data of the Tsangpo including Enginnering Geological Data of the Dams features for its analyzing whether its is going to the region as well as to the country be effected or not. Any upstream dam at a maximum altitude is a major concern and the setting up a Dam in the Namcha Barwa region is seriously a vulnerable option where it begins to drop it altitude abruptly. China should take up the matter with the Delhi as concern to the water safety and its risk hazards of the region and to maintain the ecological balance. Earlier, Chinese counterpart had given statement that the proposal of diverting water from the Tsangpo is not only unnecessary but also an unfeasible exercise and Chinese water resource minister Wang Shuchengs declared that there was no need for such dramatic and unscientific project. But this satellite image of Tsangpo at Namcha Barwa indicates that China is well ahead for their huge planning to build a dam on Tsangpo without concerning the matter of catchments sharing countries like India and Bangladesh and to be affected to Myanmar and Bhutan also. It may be mentioned here that this plan of diversion of water from Tsangpo was published in an American journal way back in 1996. This is also true that such an attempt was going on continuously and China must have now shelved the plan considering that the project involves major financial and technical difficulties. Now Arunachal Pradesh and Assam should harmoniously strive to gain as much as possible from their huge water resource base. This is the time to evaluate the present status of the Brahmaputra and explore strategy for the future to plan a programme of basinal water management system that will require a joint study of both the relevant Government Departments with the help of latest technology. However, as the major parts of the catchments of areas of Manas and Pagaldia rivers falls in the neighboring Bhutan, it is hope that that Delhi takes up the matter with Thimphu for mutually beneficial long term policies.About the Author:
