Human settlements, like towns and cities, have changed the paths of rivers a lot over time. Here are some important ways this has happened:
Urbanization: As cities grow, they can change how rivers flow. For instance, the Thames River in London has been made straighter and has banks built up to help with boat travel and to prevent flooding.
Agricultural Practices: Farmers use irrigation and drainage systems to manage water. This means they can change the direction of river water. Since crops need a steady supply of water, this can disrupt how rivers naturally flow.
Pollution: Factories and city areas can pollute rivers. This pollution can harm the plants and animals living in and around the water.
Dams and Flood Control: Structures like the Hoover Dam change river paths to create energy and control floods. They also create large areas of water called reservoirs.
These changes can impact local ecosystems, the quality of water, and even affect the weather.
