2022年6月10日 · Dams are often built to control floods, but on certain kinds of rivers they may make big deluges worse, a new study finds. The finding suggests river managers might need to rethink their flood control strategies on silty and sandy lowland rivers.

2023年8月3日 · To comprehend the effectiveness of dams in mitigating flood damages, we further break down this variable into three components: c1) the percentage of dammed rivers, c2) the presence of dams with flood control functions, and c3) …

Dams. Dams provide flood control and also serve many other purposes: water storage, recreation, navigation, electrical generation, and irrigation. Flood control dams keep floodwaters impounded and either release floodwaters in controlled amounts downstream to the river below or store or divert water for other uses.

Flood management describes methods used to reduce or prevent the detrimental effects of flood waters. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff.

2024年10月24日 · Dams are often built with the primary objective of flood control. By capturing excess rainfall and controlling water discharge, they help reduce the volume of floodwaters that flow downstream, preventing widespread flooding in vulnerable regions.

2021年1月18日 · Globally, flood risk is projected to increase in the future due to climate change and population growth. Here, we quantify the role of dams in flood mitigation, previously unaccounted for in...

2024年7月5日 · Flood control dams, also known as detention dams, are constructed to manage and mitigate the flow of water in rivers and streams. Flood control gates are strategically placed in locations where they can effectively control the water discharge during heavy rainfall or …
