A study just done by me in the 80-100 and 100-120 longitude bands shows that dams on the Indian subcontinent are causing beyond design basis forces and bending moments on the Kosi barrage and embankment system causing their breaching and catastrophic eastward shifts(this year by 120 kms). This is on account of the earthquakes caused by the dams resulting in massive upward and downward shifts at the faults alternately during the monsoon and dry season respectively. During the predam era there was mainly a westward shift of the river because there was a net uplift sloping towards the West. During the dam era there were massive net subisdences year after year resulting in dramatic Eastward shifts of the river because the subsidences sloped Eastwards. During the period 2007-2008, a massive subsidence in the hydrological year 2007 was followed by a massive uplift in the present monsoon of 2008 and the engineering structures just could not bear the strain.
Man has to design around his fallibility by giving way to reforestation on a war footing. Forests are marvels of intrinsic control of rainfall and sun to which they are exposed. Read and comment on my new URL:
