Conservation looks good too

A recent study by Washington State University researchers found that adding more natural buffers to farm landscapes can not only slow soil erosion but also create more visually appealing fields and valleys. The study surveyed residents in the Palouse region of eastern Washington State, who preferred landscapes with more nature and fewe...

Salvaging the ecosystem after salvage logging

A study published in Forest Ecology and Management found that salvage logging increases sediment in water runoff, causing erosion and damage to fish habitats. Leaving slash on the ground, breaking up equipment trails with water bars, and replanting vegetation are recommended best management practices for minimizing ecological effects.

Humans erode soil 100 times faster than nature

Researchers found that rates of hillslope erosion before European settlement were about an inch every 2500 years, while during peak land disturbance in the late 1800s and early 1900s, rates spiked to an inch every 25 years. This indicates a 100-fold increase in soil loss due to human activities.

Study finds way to conserve soil and water in world's driest wheat region

Researchers at Washington State University identified summer fallow management practices that can help farmers conserve soil, prevent sky-darkening dust storms, and improve air quality. Undercutter-tillage or no-till fallow systems were found to be the most effective options for reducing wind erosion in the Horse Heaven Hills region.

Tree rings and arroyos

Researchers use tree rings to date arroyo sedimentary beds and combine data with aerial imagery and LiDAR to reconstruct the history of these arroyos. The study reveals that arroyos are unstable features that shift between broad floodplains and incised channels, and that upstream progression is limited to specific locations.

Aging Africa

Researchers in southern Africa used beryllium-10 and aluminum-26 to measure erosion rates, finding five meters per million years in non-tectonically active regions. This rate is significantly lower than basin-average erosion rates, with stable upland surfaces remaining unchanged since the Pliocene.

Warning to parents on high acidity drinks

Researchers at the University of Adelaide found that acidity from soft drinks and fruit juice can cause lifelong damage to young people's teeth within 30 seconds. Parents are advised to limit their children's consumption of acidic beverages to prevent long-term dental issues.

Examining the causes of a devastating debris flow

A recent study by Ren examined the causes of a devastating debris flow in China, which killed over 1000 people. The research found that geological conditions, surface loading, vegetation roots, and extreme precipitation all contributed to the disaster.

3-D printer for the world's largest delta?

Researchers used geochemical fingerprints to reconstruct the history of the Ganges-Brahmaputra-Meghna delta, finding a history of mobile river systems that built the delta like a 3-D printer. This understanding is crucial for the 150 million people living on the delta, who face regular flooding and erosion.

The physics of ocean undertow

A new paper in Physics of Fluids provides a more consistent way to describe the forces acting on waves and undertows. The researchers found that different approaches were due to incorrect handling of weak forces, not methodology. This advance enables better models for predicting beach erosion and can help preserve shorelines.

Frozen in time: 3-million-year-old landscape still exists beneath the Greenland ice sheet

Researchers funded by NSF discover that some landscapes underlying the massive Greenland ice sheet may have remained undisturbed for almost 3 million years. The team analyzed chemical composition of silts from an ice core and found evidence of a continuous cover of Summit, Greenland, with minimal surface erosion during warmest periods.

Research reveals true value of cover crops to farmers, environment

A study published in Agricultural Systems found that planting cover crops increases eight of eleven ecosystem services, including carbon and nitrogen retention, erosion prevention, and weed suppression. The research highlights the importance of considering temporal dynamics when assessing management system effects on ecosystem services.

Where nothing grows anymore

Researchers found that high sodium concentrations in the soil lead to instability and increased erosion in Tuscany's Crete Senesi badlands. The presence of vegetation helps stabilize the ground, but agricultural use is eroding the landscape, threatening its disappearance in 35-40 years.

Study offers economical solutions for maintaining critical delta environments

A new study by Woods Hole Oceanographic Institution researchers documents the historic sediment record along the Danube River delta and offers simple and inexpensive strategies to maintain delta environments. The team analyzed sediment cores and found that mimicking natural distributaries can help keep sediment on flood plains, rather ...

The physics of beer tapping

Researchers explore beer bottle-fluid interactions using cavitation analysis, explaining the formation of foam due to rapid expansion of smaller bubbles. The study's findings can be applied to other engineering concerns, such as erosion of ship propellers and carbon dioxide release in natural disasters.

Soil carbon 'blowing in the wind'

A new study reveals that Australian soils are losing significant amounts of carbon to wind erosion, with an estimated 1.6 million tonnes lost annually. This loss affects not only agricultural productivity but also the country's carbon accounts and climate change projections.

Fewer states holding alcohol retailers responsible for harms from illegal service

A new report finds that fewer states are holding alcohol retailers liable for harms caused by customers who were served illegally, leading to reduced protection against excessive drinking. The erosion of commercial host liability laws is seen as a public health failure contributing to high human and economic costs.
