@Nuralain : thanks please also answer these questions Q2.do u think that the discharge of water in the rivers in general and the Kosi in particular ,remains the same, or does it fluctuate? Q3. When does the river course receive maximum quantity of water?
It fluctuates for almost all the rivers, including kosi. Maximum quantity in july-august, due to heavy rainfall and melting of glaciers during the summer months of may-june.
1) kosi has one of the largest alluvial fan in the world. 2)construction of unsustainable embankments, which only raised sediment deposition over the river beds. 3)like any other Himalayan river, kosi too comes down with good gradient 4) kosi is an antecedent river. Means, kosi does not care about underlying rock structure. In simple words, kosi's way is its way. 5)we know the rainfall during south west monsoon season decreases from east to west in the northern plains, kosi is one of the left east most tributary of Ganga.Huge rainfall implies more drainage but not much capacity to hold increased water. 6)like any other himalayan river, kosi too shifts channels, meanders thus bank erosions happen more frequently when you add some of the above factors. 7) political reasons like poor water mgmt between Bihar and Nepal regarding flood mgmt for fear of losing more in any negotiations. I hope, this helps. Cheers!
.Consider the following statements 1. The West flowing rivers contains very less amounts of Silt and due to its fast speed it cannot make delta. 2. Rivers arriving into a sea with high tidal range will not form delta because the changes in the tidal area will wash away the sediments brought by the river. 3. Western rivers flows in the fault region created by the mountains Vindhya and Satpura which are rocky and devoid of any alluvial material. Hence no Delta formation Select the correct statement/s 1. Only 1 2. 1 and 2 3. 1, 2 and 3 4. Only 2

Can anyone explain formation of westerlies to me? Is pressure at Sub tropical High higher than pressure at sub polar low? Because subpolar low are called 'low' as their pressure relative to polar high is lower. But if SPL pressure is actually higher than STH then how are westerlies flowing upwards? If STH is indeed higher than SPL, then I can understand the direction of flow.

4. Only 2
Ans is 1 only. bcoz take ganga-brahmaputra delta ,they have high tides but delta formation is present.
West flowing rivers have high gradients and running very fast, so rivers have less chance to spread out.
