LA lawns lose 70 billion gallons of water a year

Blog— In summer 2010, Los Angeles was losing about 100 gallons of water per person per day to the atmosphere through the evaporation and plant uptake of lawns and trees, new research finds. Lawns accounted for 70 percent of the water loss, while trees accounted for 30 percent, according to a new study.... more

Geological entropy and solute transport in heterogeneous porous media

Editor’s Highlight—   This paper addresses a major challenge: anticipating or predicting groundwater solute transport behavior in realistically heterogeneous geologic media using knowledge of certain quantitative metrics about the system heterogeneity. In recent years, subsurface hydrologists have begun.... more

Modeling blowing snow accumulation downwind of an obstruction: The Ohara Eulerian particle distribution equation

N.J. Kinar, Global Institute for Water Security, University of Saskatchewan

Commentary in Water Resources Research Snow is carried by wind, and snowdrifts often accumulate downwind of trees, a fence, a building, or a mountain ridge. Ohara [2017] came up with a math equation that can determine the shape of the snow drift without the need for measurements of wind speed. This.... more

The importance and challenge of hyporheic mixing

Editor’s Highlight—   This Commentary discusses the possible processes that cause mixing of stream water and groundwater in the hyporheic zone in the light of literature on mixing processes and mixing controlled reactions in porous media and aquifers. The authors suggest new areas for research based.... more

How Do Rivers Flow over Bedrock?

Terri Cook, Freelance Writer

From Research Spotlights— A study questions whether the hydraulics of rivers that lack loose sediments along their bottoms can be accurately depicted by standard equations for flow over sediment.  Several centuries of scientific inquiry into the factors that control a river’s velocity and.... more

Lab Tests Probe the Secrets of Steep and Rocky Mountain Streams

Sarah Witman, Freelance Writer

From Research Spotlights—   Researchers build a glass-encased test environment that helps them assess streamflow without the confounding factors introduced by bed forms. Water flowing over a mountainous landscape can be serene or tumultuous, depending on a variety of physical factors: how much.... more
