Lincoln, Boozman Face New Candidate - Politics News Story - KHBS NW Arkansas

UA stream study confirms the affect of paving and filling in all the natural places has on the streams that originate in our city: Other students have been studying the Town Branch at 15th Street and another stream in the White River/Beaver Lake watershed as well as a couple in the Illinois River watershed

Stream study reveals  facts that local conservationists have recognized for years. Wonderful that UA is actually studying its  hometown. Far too much research is done far away, even half-way around the world.

Study Findings Have Impact Up and Down Stream

Findings have implications for managing streams

Thursday, July 29, 2010
FAYETTEVILLE, Ark. – A University of Arkansas researcher and her colleagues examined streams in urban, agricultural and forested settings and determined that the differences they found may affect how cities try to restore urban streams.
Geosciences researcher Stephanie Shepherd, geosciences professors John C. Dixon and Ralph K. Davis, and graduate student Rose Feinstein report their findings in River Research and Applications.
Shepherd’s work examined the shape of headwater streams, as well as the materials found in them, in cities, on farmland and in forested areas in the Illinois River watershed in northwest Arkansas. She found that the material in streams shifted from gravel in the forested streams to a high percentage of bedrock in the urban streams. Scientists know that urban streams run deeper and faster than forested streams, but until now the reasons haven’t been completely clear.
“The research shows one way that change is occurring in these streams,” Shepherd said. “It also suggests that just making an urban stream look like a forested stream will probably fail.”
To arrive at this conclusion, Shepherd looked at floodplains, measured depths and counted pebbles in streams at several sites in each land use category as determined by land use surveys – urban, agricultural and forest. Forested sites had more sinuous streams than the agricultural or urban sites. The forested streams had meander bends with gravel bars, which were absent in the urban and agricultural streams. Urban streams also ran significantly wider and deeper than those found on farmland and in forests.
The biggest difference between streams occurred in the materials found in the different settings. Urban streams had a lot of exposed bedrock, while agricultural streams had less than 1 percent exposed bedrock and forested streams had no exposed bedrock.
The exposed bedrock in urban streams occurs when cities harden the banks of a stream, create drainage channels or pave and reinforce the landscape surrounding it. This decreases new input into the urban stream. It also forces water into the stream that, in a forested setting, would be absorbed into the ground. This forced water produces high-speed flow, which then moves material such as stones and pebbles through quickly, sometimes scouring the bottom of the stream all the way to the bedrock.
 “Streams are not static – materials are moving through them at different velocities all the time,” Shepherd said. “If there are not new gravel inputs in urban streams, we have to think of them as a different system.” Many of the physical characteristics surrounding forested streams, such as large areas of undisturbed soil, cannot be reproduced in an urban setting, she said, so scientists should explore new ways besides simple restoration to mitigate urban streams.
Shepherd and her colleagues work in the department of geosciences in the J. William Fulbright College of Arts and Sciences at the University of Arkansas.

Oil spill in Louisiana wetlands (by Office of La. Gov. Jindal)
Take Action
Dear Aubrey,
This week the House of Representatives is planning to vote on a critical bill to rein in the oil and gas industries. Please tell your Representativeto vote YES on H.R. 3534, the CLEAR Act.
The CLEAR Act will help reverse the disastrous policies that resulted in the Gulf oil spill and other disasters. This bill will not only protect our oceans from future spills, but will protect our rivers, streams, land, and the communities that depend on them.
Tell your Representative to protect rivers, water, and the communities that depend on them by voting YES on H.R. 3534!

Workshop Information

  • Date: July 29 and 30
  • Location: Fayetteville Town Center, Fayetteville, AR
  • Cost: $35.00 until July 1, and $50.00 after July 1
  • Agenda
  • Contact Us

EPA Region 6, the Northwest Arkansas Stormwater Education Group, the University of Arkansas Cooperative Extension, the Illinois River Watershed Partnership, and the Beaver Water District are proud to announce the "Managing Wet Weather with Green Infrastructure" Workshop to be held July 29th & 30th at the Fayetteville Town Center in beautiful downtown Fayetteville, AR.

What is Green Infrastructure?

Green infrastructure is an approach to wet weather management that is cost-effective, sustainable, and environmentally friendly. Green Infrastructure management approaches and technologies infiltrate, evapotranspire, capture and reuse stormwater to maintain or restore natural hydrology. Additional information on EPA's green infrastructure program is available at

Why attend?

Participants will leave the conference with knowledge of tools and practices needed to effectively implement GI and different approaches to linking GI to prevent/mitigate water quality impacts. This meeting will be highly informative and will benefit all participants. Continuing Education Units (CEUs) may be available.
