The most common reason to dredge a river is to provide depth for water traffic, allowing boats, ships, and barges to travel safely. Other reasons can be to avoid flooding up river from a channel being clogged or backed up. In some cases this will insure that the channel doesn't reform in another place, causing damage to homes, roads and bridges. Another reason is to eliminate silt which can fill in lakes, ponds and behind dams. This can cause flooding and damage hydroelectric plants.

The Truman Doctrine and The Marshall Plan further defined and deepened the Cold War in Europe because, Stalin grew wary of the American's, he never particularly liked Truman, one can see this in the difference of Yalta and Potsdam. - So when Truman went around - beating communism down, (he never used the word Communism), but he made it very clear- Stalin grew less trustworthy of the Americans.- Hence, the Marshall Aid in particular, deepened the 'bad feeling' between the two superpowers, and therefore deepened the Cold War tensions.
