New report predicts extreme precipitation in global dry and wet areas

A new study warns that extreme precipitation over land will increase in the world’s wettest and driest areas, with the hydrological cycle intensifying as a result of global warming. Released by Nature Climate Change, a monthly journal dedicated to publishing the most significant and cutting-edge research on the science of climate change including its impacts […]

New phosphorus reduction targets aim to reduce toxic algae blooms in Lake Erie

The U.S. and Canadian governments have adopted targets to reduce phosphorus entering areas of Lake Erie by 40% in an effort to improve water quality and minimize risks to public health. The reductions seek to decrease the amount of low oxygen “dead zones” in the central basin of Lake Erie, encourage algae growth at a […]

Guide Examines Community Adaptation to More Frequent and Intense Rainfall

With the potential for more frequent and intense storms as part of a changing climate, communities now are looking at how they manage rainwater and flooding. Minnehaha Creek Watershed District (MCWD) partnered with two Twin Cities’ communities — Minneapolis and Victoria — in a federally-funded study that examines the effects of changing rainfall patterns and […]

Flood Models Should Include Cities’ Effect on Rainfall

Current flood models do not account for cities’ effect on local rainfall patterns, which could lead to significantly underestimating the severity and frequency of floods in urban areas, a study finds. Purdue Professor and Indiana State Climatologist Dev Niyogi and collaborators at China’s Tsinghua University showed that impervious city surfaces can influence dramatically the way […]

EPA Launches New Tool to Support Community Interest in Green Infrastructure

The Green Infrastructure Wizard, or GIWiz, is a new web-based tool from the U.S. Environmental Protection Agency (EPA) that is helping communities consider the benefits and uses of green infrastructure. The tool responds to growing community interest in using green infrastructure as a means of addressing water quality concerns and a range of other local […]

USGS Releases Pesticide Mapping Tool

On Sept. 16, the U.S. Geological Survey (USGS) released a new interactive mapping tool that provides predicted concentrations for 108 pesticides in streams and rivers across the United States. The tool enables users to identify which streams are most likely to exceed water-quality guidelines for human health or aquatic life. The predictions also can be used […]

Freshwater Trust Methodology Helps Prioritize Water Resource Projects

The Freshwater Trust will expand a methodology based on geographic information systems (GIS). Known as StreamBank® BasinScout™, the trust will use this methodology to assess and prioritize potential restoration opportunities in California’s Russian River basin. Snaking southward and draining Sonoma and Mendocino counties, the Russian River provides drinking water for several hundred thousand Californians and […]

EPA Releases Climate Adjustment Tool

On Feb.13, the U.S. Environmental Protection Agency (EPA) announced the release of the Climate Adjustment Tool for its Stormwater Management Model — a widely-used, downloadable online stormwater simulation model. The Climate Adjustment Tool enables engineers and planners to evaluate the performance of water infrastructure while considering future such climate change projections as more frequent high-intensity […]

Australian Researchers Assess New Ways of Calculating Flood Risks

University of Adelaide researchers are devising new methods to more accurately estimate long-term flood risk across Australia. Researchers are examining the possible causes of floods and how they interact with each other. This information is being used to create sophisticated models which will be used by engineers to better calculate flood risks for different locations. […]
