Dam and its environmental impact
 

With the ongoing debate on building dams from all sides of the society, I have a feeling that dam construction will cause adverse impacts more than it will save water. For instance, dam will divert the natural flow of rivers downstream and can cause sedimentation problems, especially for inhabitants living around it. I need opinions of environmental experts or students who can disucss adverse effects of dams.

No one seems to be interested in discussions, despite a large number of capable people here, disappointed

Creating dams is a good cause, but maintaining it is the challenge. Take, for example, this water which flows from the mountain comes with natural sand which is useful to control the sea which eats the land of Sindh. If dams are built, it should be well maintained and the sand which sits at the bottom of their soil should be transferred to rivers to fill the gap.
Sindh has the objection over many dams, just create thousands of dams but for Sindh launch desalination plant.
This solution is simple, Sindh has Sea so it should be provided with its fair right to filter the water. Take the example of Isreal, so why not Sindh can be self-sufficient with this sea water.

It is acknowledged that Sindh has been deprived of its full water rights, i.e. Kotri, which should have atleast 10MAF per year is getting less than 7MAF from Indus river. I'm also concerned with the issue that how Karachi, hyderabad, and other major cities will be benefitted from this dam. Making a single dam might not suffice the problem of other provinces and they should build their own dams to be equalized in terms of water capacity.
