What is Una Levee?

An embankment is an artificial or natural wall that prevents water from leaving its course. It can also be used to divert the river to increase land for construction. In some countries, embankments are used to prevent water from flowing into the hinterland from the sea or to divert the course of the river revealing fertile soil. They can also be used to prevent rivers from overflowing into cities during storms. They are very important features but if they break down the consequences are disastrous.

Most embankments are formed from terrestrial material. The flow of a water body pushes the river sediments to the sides thus creating an embankment. The embankment forms an embankment made of silk, sediments and other materials like dead plants on the side as the water flows. They extend parallel to the river and control the flow. The natural banks can be reinforced with artificial material. In cases where the banks do not exist, the artificial ones are built. They are made by accumulating rocks, sand and earth along the river bank. When the flow of the river is too strong, they can be made of metal, wood or plastic. In some places they are made of concrete.


The artificial banks are built to prevent flooding but create a new problem by channeling the river through a narrow opening. When the water is channeled through a narrow opening it increases its power and height. More pressure is exerted on the banks downstream making the water even more difficult to control. In 2005, Hurricane Katrina caused a storm that invaded the Mississippi River, the river banks were swept away, leaving 80 percent of New Orleans under water.

History of Levees

With 2500 BCE, civilization in what is today Mohenjo Daro, in Pakistan, built embankments to protect their plants from flooding. In addition to controlling the flow of water, the banks were used to protect villages from invaders. In 1938 the Chinese intentionally broke their banks along the Yellow River to prevent Japanese forces from crossing their territory. About 500,000 Chinese and Japanese died due to the flood.

Sea Levees

Most of the leaves are used to control the flow of the river, but others are built along the coast. The Netherlands is a prime example of how embankments and dams can be used to control tides. The reclaimed land is then used for agricultural or residential use. An embankment was also built along the coast of the Bay of Fundy in Nova Scotia and New Brunswick to prevent the high tides from flowing inland.
