The surge of 1973 that caused such a great amount of harm to the Old River Control Structure was the effect of numerous things. There were bizarrely overwhelming snows in the upper valley. The South of the state got an extraordinary measure of precipitation. In the long run, the spillovers came down to the tributaries, developed, and eventually flagged PCs an admonition that the mainline levees were not satisfactory to contain the measure of water gathered. In a condition of frenzy there were sandbags, potato edges and obstructions of uncompacted earth added to the levees to attempt to forestall a flood. During the kept spring high water the gathered seepage all met up at Old River in units surpassing 2,000,000 cubic feet for each second. Twenty-five percent of that left the Mississippi channel and went to the Atchafalaya. Teacher Racphael G. Kazmann recalls his experience strolling over the structure before the surge of 1973. Kazmann reviews, â€Å"That entire hopeless structure was vibrating This thing gauges 200,000 tons. At the point when 200,000 tons vibrates this way, this is a bad situation for R. G. Kazmann.

The development of levees along the lower waterway that channel water and dregs past New Orleans and out into the Gulf. This has halted sedimentation all through the delta, and the delta is presently quickly sinking beneath ocean level. On the off chance that the levees didn't exist the waterway channel conveying the majority of the stream water would change position, and store silt all through the delta. The digging of numerous channels to give access to oil and gas wells. The trenches assist salt with watering arrive at further inland, bringing about death of trees and vegetation that balances out wetlands. Wind blowing along the waterways produces waves that dissolve the banks. What's more, storm floods created by storms travel along channels causing disintegration further inland. All zones are not disintegrated at a similar rate during a tempest. A few regions have serious disintegration during an occasion. Different zones have significantly less disintegration.
