Subsequent testing indicated that early levelers sometimes failed, but the concept has evolved. Modern devices control water height using a flexible plastic tube resting on a pond’s bottom.

2 days ago · Beavers—please forgive me—are pretty dam cool. They build their homes (or lodges) underwater, creating a safe space by stacking together tree branches, rocks, mud, and grass.

Beaver dams flood valuable timber and beavers cut down thousands of trees around their dams. However, the flooding leads to increased fertility in the land, which is favorable to new plant and animal life.

Jul 5, 2023 · But on January 9th, that final atmospheric river caused all of their dams, lodges, bank dens to wash away in the heavy rains. Entire riparian areas were either buried deep under sand and water, or literally uprooted, turned upside down and moved downstream.

of beaver dams on sedimentation rates, channel morphology, and channel stability needs to be quantified across a diversity of study areas. This paper presents a case study of the impacts of beaver dams on a low gradient, fine-grained alluvial channel on the Atlantic Coastal Plain. A human-built dam on a river in eastern Virginia was breached.

But a new study in Environmental Science and Technology, a journal of the American Chemical Society, shows that restoration is having an unintended side effect. Levels of methylmercury are 3 and 1/2 times higher downstream from newly constructed …

Spillways, stop-log bays, and drop inlets are susceptible to blockage through the action of beaver. The presence of debris can act to reduce the discharge capacity of a dam, raise the pond, or produce sudden high outflows should the debris obstruction fail.

Nov 8, 2022 · Here, we show that beaver dams overshadow climatic hydrologic extremes in their effects on water residence time and oxygen and nitrogen fluxes in the riparian subsurface.
