Dam you!

Man said it to the river, and dammed it.

In so doing, did he or did he not damn(pardon the swear word) himself?

A flowing river was made into lakes. Agricultural lands, man's dwellings, forests, flora and fauna were inundated and lost. The regular supply of silt that the river provided oh so generously to the land it flooded was stopped. Instead this silt deposited itself in the river bed, making it go shallow over the years and causing the extra cost 0f desilting. Man grew confident of the mighty walls of the dam, and hence occasional wall breakages and subsequent flash floods took him so much by surprise that he lost much.

In return, he got electricity (mind you, not all dams can yield electricity), an assurance that he will get water for agriculture all the year round in just the right amount.

Imagine now, a scenario without dams.

The average villager knew well the level to which river water was likely to reach. Cleverly, he prepared himself for it - by collecting his stuff and moving up to higher up areas referred to as 'Gadhs' (You may still here about gadhs and even get to see them in several villages of North Bihar). The river would come, spread its silt on his agricultural fields, and in its own time, recede. The farmers would return, and enjoy a decent harvest sans fertilizers.

North Bihar gets flooded every year, notwithstanding the amount of rainfall. This is because of the millions of gallons of water that flows down the Himalayas every monsoon. Every year we hear of at least one river that has broken its embankment and caused floods. Every year we hear of villages plunged into misery.

Have embankments really helped? Would it have been better to provide for maintenance of level-markers to indicate which level a river is likely to reach during an average flood and prepare more 'gadhs' than embankments?

I am not able to understaand the reason why man is so afraid of the concequences of his efforts to mould the enviornment to his needs...

It doesnt have to be reckless.. agreed.. but blaming floods and the plight of bihar on the dams does'nt go well with me..

Why cant we see how can we control the floods.. why not build a dam big enough to hold water of the mighty Brahmputra.. and Holy ganga..

We need water.. Have faced water riots in Tm and Karnatka.. Rajasthan and Punjab are in court over water.. Gujrat is facing crisis.. and what do i say about the plight of Delhi and Mumbai..

Lets store water.. Lets have a life.. Lets build BIG Fresh water lakes..

Dont worry Humans.. Just be carefull....

Yes, quite right. There is no need to be afraid, but there is every need to be careful and logical, to check the possible consequences of each activity and, above all, to do a cost benefit analysis before proceeding.

One remedy cannot be used for every malady. Embankments for North Bihar is an inferior measure than the constructions of retreat routes for villagers and 'gadhs'.
See, Bihar has, touchwood (!), a decent supply of ground water. Secondly, a large dam cannot be built here owing to the tectonic unstability of the terrain. (Don't know how correct is that?!)

Doesnt matter even if u r wrong.

I dont even know which language "tectonic unstability of the terrain " is..!!
