We all know about AI (Artificial Intelligence) emphasize the creation of machine that can react like humans. But, Machine Learning is one step ahead of AI, which is just like a real intelligent human. The human race is evolved by their discoveries made during a particular period of time. When these discoveries are kept in sequence, the discovery which brings the biggest change in the world are said to be revolution. In the history of evolution, the technology which are closely interacts with humans are supposed to bring these revolutions in the past.

When the last tree has been cut down, the last fish caught, the last river poisoned, only then will we realize that one cannot eat money! — Cree Proverb Rivers are the main source of development in human civilization. A river which originates in the mountain flows down as tiny stream and fed by glaciers or rain water running of the land which then meets with other small streams of water and join together, growing as river. As the river flows, exchanges its mineral resources with the surrounding environment and pervades every facet of existence for life. River ecosystem is the biological power source of the planet. The important part in this ecosystem is the place where the river and sea meet together (Estuaries). This fusion is stopped by building dams which lead many vulnerabilities and consequences. When the river ecosystem is interpreted, it not only affects agriculture but also the aquatic environment. Estuaries are a habitat for many aquatic organisms with high lev
