hydro is bad because it can block up rivers, cutting off marine life from crossing over the dam to nesting grounds and such
timber = wood dam = structure built to block/slow the flow of water so... timber dam is a wooden structure created to block or slow the flow of water.
Colonies sometimes dammed or blocked rivers to control water flow for irrigation, drinking water, and other agricultural needs. This allowed them to manage water resources more effectively, ensuring a stable supply for farming and settlement. Additionally, such actions could help prevent flooding and create navigable waterways for transportation and trade. Ultimately, these measures were vital for sustaining growing populations and economies.
A dam
The Amazon River.
Dam if I know. Sorry couldn't resist. It is a dam that crosses rivers to control the water flow. Dam's come in all sizes, shapes, and materials. One of the largest dams in the world is the Aswan dam that crosses the Nile River. It's a huge edifice made of cement and steel. Probably the smallest dams are the ones built by beavers. They use gnawed off branches and trees to block up small streams. Lots of man-made dams are built to provide hydro-electric power for the regional area. Hoover Dam in Nevada USA is such a dam. Others are built to provide flood control so that areas downstream don't get flooded out during heavy rainstorms for example. The Aswan Dam is both a flood control and power providing dam.
They build dams in rivers because they can get electricity from the energy of water without pollution and it is safe.
Controlled land use, widen rivers, deepen rivers, build a dam
The Aswan Dam
nile river, lake nasser, aswan dam.
No, because precipitation is what helps the plants and a dam's water cant reach those plants unless the block lets the water evaporate into the clouds.
it is a dam that holds back water and it blokes the water like lakes,rivers and the ocean.
