GPS helps locate soil erosion pathways

Grassed waterways are placed in agricultural fields where runoff water tends to concentrate because they can substantially reduce soil erosion. Mapping techniques that help identify where erosion channels will likely form ...

GrayQb: A new tool for radioactive contamination mapping

Nuclear facilities in the midst of cleanup due to normal routine or unexpected incident face a remarkable challenge – how to safely determine the exact location of radioactive contamination. Such determinations are typically ...

Warmer temperatures cause decline in key runoff measure

Since the mid-1980s, the percentage of precipitation that becomes streamflow in the Upper Rio Grande watershed has fallen more steeply than at any point in at least 445 years, according to a new study led by the National ...

Warmer climate not the cause of oxygen deficiency in the Baltic Sea

Oxygen deficiency in the Baltic Sea has never been greater than it is now. But it is not an effect of climate change but rather of increased inputs of nutrients and fertilisers. This is the finding of researchers at the University ...

Trading farmland for nitrogen protection

Excess nitrogen from agricultural runoff can enter surface waters with devastating effects. Algal blooms and fish kills are a just a couple of possible consequences. But riparian buffer zones - areas of grasses, perennials, ...
