In United States agricultural policy, Highly erodible land (HEL) refers to land that is very susceptible to erosion, including fields that have at least 1/3 or 50 acres (200,000 m2) of soils with a natural erosion potential of at least 8 times their T value.

Comparing Volumetric and Gravimetric Suspended Sediment Concentration Data From a Midwest Stream

Comparing Volumetric and Gravimetric Suspended Sediment Concentration Data From a Midwest Stream

The ability to categorize suspended sediment metrics (e.g., total concentration, mean particle size, particle size class) to specific land-use types is increasingly appealing in terms of better targeting mitigation strategies. However, innovative real-time in situ instruments that advance monitoring capabilities often provide results that are not readily comparable to traditional

Moving Toward Green in Omaha

Moving Toward Green in Omaha

As Kermit the Frog is known for singing, sometimes it’s not easy being green. And sometimes it isn’t easy being—or implementing—green or gray infrastructure, at least when it comes to managing stormwater on a budget and under challenging conditions, such as those found in Omaha, NE.

Tracking Tree Canopy (Overall, We’re Losing)

Tracking Tree Canopy (Overall, We’re Losing)

Last week I wrote about urban trees and how some US cities are recognizing—and helping the public to recognize—their value.

Unfortunately, the global outlook for trees isn’t looking as good. One organization has estimated that since 2000, the world has lost about 6% of its tree cover.

One focus of the organization,

What Flows Beneath: Tracking Underground Pollutants

What Flows Beneath: Tracking Underground Pollutants

Missouri University of Science and Technology announced this week that one of its researchers has found a way to predict how water flows underground—and how pollutants travel with it. Dr. Xiaoming He, an assistant professor of mathematics and statistics, is using a mathematical model to simulate how water follows fractures,

Editor’s Comments: A New Way to Estimate Pollutants

WE’VE REPORTED before on tools available at little or no cost to help us do various aspects of our jobs. Digital Coast (www.
coast.noaa.gov/digitalcoast), from the National Oceanic and Atmospheric Administration (NOAA), is one of these; it’s an interactive program that helps managers in coastal areas gauge their vulnerability to flooding
