Grand Coulee Dam is a concrete gravity dam on the Columbia River in ... (41 °C) to 45 °F (7 °C). This caused the dam to contract about 8 inches (20 cm) in length ...
A beaver dam or beaver impoundment is a dam built by beavers; it creates a pond which protects against predators such as coyotes, wolves and bears, and holds their food during winter. These structures modify the natural environment in such a way that the overall ecosystem builds upon the change, making beavers a keystone species and ecosystem ...
The word dam can be traced back to Middle English, [1] and before that, from Middle Dutch, as seen in the names of many old cities, [2] such as Amsterdam and Rotterdam. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. Egyptians also built dams ...
The following table lists the largest man-made dams by volume of fill/structure. By general definition, a dam is a barrier that impounds water or underground streams, hence tailings dams are relegated to a separate list.
