The Connected Consequences of River Dams

In a case study of dams on the upper Missouri River, USGS researchers have demonstrated that an upstream dam is still a major control of river dynamics where the backwater effects of a downstream reservoir begin. In light of this finding, the conventional understanding of how a dam can influence a river may have to be adjusted to account for the fact that effects of river dams can interact with one another.

“We have known for a long time that dams have dramatic effects on river form and function,” said Jerad Bales, acting USGS Associate Director for Water. “In the past, however, the effects of dams generally have been studied individually, with relatively little attention paid to how the effects could interact along a river corridor.” (more…)

Why is DAM the Best Tool to Manage Your Digital Data

Digital Asset Management, also known as DAM is a technology that helps you to store, archive, organize, distribute and access digital media. Digital media may include documents, videos, images or any other types of files. In this article, we will tell you why Digital Asset Management is the best tool to manage your company’s digital data. DAM can be used for both personal and organizational purposes. However, before we move on to the benefits of Digital Assets Management, it is important to understand the concept of assets.

In DAM systems, all kinds of digital data like images, videos, documents etc. are known as assets. Time, money and resources are usually used by an organization to create assets in the form of files. With the advancement in technology, it has been quite easy to store and access these files digitally. Therefore, this definition of DAM systems came into existence. Basically, Digital Asset Management describes processes and technologies that aim to maximize the return on file investments in an organization.  (more…)

American Eels Return to Mountain Streams after Dam Removal

Shenandoah National Park, Va. – American eels are declining across their range but are showing indications of a population revival following the removal of a large dam in Virginia.

The removal of Embrey Dam on the Rappahannock River increased American eel numbers in headwater streams nearly 100 miles away, according to research just published by U.S. Geological Survey, U.S. Fish and Wildlife Service, and National Park Service researchers.

American eels undergo long-distance migrations from their ocean spawning grounds in the Sargasso Sea to freshwater streams along the Atlantic coast from northern South America to Greenland. Dams may slow or even stop upstream eel migrations.  However, prior to this research, little was known about American eel responses to dam removal. (more…)
