If you've ever stood on a hill during a rainstorm, you've probably witnessed landscape evolution, at least on a small scale: rivulets of water streaming down a slope, cutting deeper trenches in the earth when the rain turns heavier. It's a simple phenomenon that scientists have long believed applies to large-scale landforms as well — that is, rivers cut faster into mountains that receive heavier precipitation. It's thought that if rainfall patterns influence how rivers cut into rock,...
HARRISBURG, Pa., July 2, 2012 /PRNewswire-USNewswire/ -- The Department of Environmental Protection is reminding homeowners and landowners who are conducting work in or along streams and wetlands that a permit may be required from DEP or the U.S. Army Corps of Engineers. "Homeowners and landowners may not be aware that state or federal law requires a DEP permit for certain types of work they want to do on their own property," DEP Secretary Mike Krancer said. "DEP is here as a...
Ecologists review the human and biological communities of wadis, arroyos, gulches, washes, and other intermittent flows 'When the River Runs Dry' is a familiar song in Australia. Some rivers in the arid center of the continent flow only after a stiff monsoon season, and smaller tributaries all over the country commonly shrink to puddled potholes and dry river beds during the dry season. But rivers also run dry in more temperate climes. Much of the upper reaches and feeder streams of the...
A new analysis of streams in the western United States with long-term monitoring programs has found that despite a general increase in air temperatures over the past several decades, streams are not necessarily warming at the same rate. Several factors may influence the discrepancy, researchers say, including snowmelt, interaction with groundwater, flow and discharge rates, solar radiation, wind and humidity. But even after factoring out those elements, the scientists were surprised by the...

An eight-year study has concluded that increasingly frequent and severe drought, dropping water tables and dried-up springs have pushed some aquatic desert ecosystems into “catastrophic regime change,” from which many species will not recover. The findings, just published in the journal Freshwater Biology, raise concerns that climate change, over-pumping of aquifers for urban water use, and land management may permanently affect which species can survive. The research was supported by...
HARRISBURG, Pa., Oct. 11, 2011 /PRNewswire-USNewswire/ -- Department of Environmental Protection Secretary Mike Krancer toured Laser Northeast Gathering Co.'s pipeline installation activities on Oct. 7, including the completed boring operations under Laurel Lake Creek in Silver Lake Township, Susquehanna County. While the company was conducting horizontal drilling under the creek for installation of a natural gas pipeline, there were several inadvertent returns to surface (IRTS) discharges...
Much of the Mississippi River's sediment load doesn't come from field runoff, according to work by scientists at the U.S. Department of Agriculture (USDA). Instead, the scientists with USDA's Agricultural Research Service (ARS) have confirmed that stream bank collapse and failure can be chief contributors to high sediment levels in the silty streams and rivers that flow into the Mississippi. ARS is USDA's chief intramural scientific research agency.The U.S. Environmental Protection Agency...
ST. LOUIS, Jan. 5, 2011 /PRNewswire/ -- A flourishing watershed at Peabody Energy's Farmersburg Mine has earned one of Indiana's highest environmental honors. The Indiana Society of Mining and Reclamation recognized the mine team with the 2010 Indiana Excellence in Mining and Reclamation Award for Natural Stream Restoration at the organization's 24th annual Technology Transfer Seminar in Jasper, Ind. The award honors the company's successful work to reconstruct a nearly 6,000-foot section...
Rising concentrations of zinc in a waterway on Colorado's Western Slope may be the result of climate change that is affecting the timing of annual snowmelt, says a new study led by the University of Colorado at Boulder.The study focused on the Snake River watershed just west of the Continental Divide near Keystone, Colo., where CU-Boulder researchers have observed a four-fold increase in dissolved zinc over the last 30 years during the lowest water flow months, said Caitlin Crouch. Crouch, a...
