New paper on streamflow response to forest management and increasing precipitation extremes

Dr. Charley Kelly, a former lab member and now with the Division of Forestry and Natural Resources, West Virginia University, had a paper accepted in Geophysical Research Letters this week.  The study re-examines several paired watershed studies from the Coweeta Hydrologic Lab, but focuses on high flows, low flows, and interactions with precipitation patterns. Abstract: Increases in extreme …

Winter is Coming

I have been going to Coweeta every one or two weeks for the past two months to monitor sprinkling events on the soil model. Although I am measuring only one thing, water, being precise is actually very difficult. There are 5 high-resolution tipping buckets on the hillslope to measure samples of input and one large …

Sprinkling on the model

Kevin, Brian, and I went to Coweeta to improve the irrigation system. They installed a pressure pump to the water line, then we placed tipping bucket rain gauges at randomized locations, and then Brian turned on the water. Water pressure was high enough! We tuned each sprinkler head so that water reached just to the …

Filtration, Irrigation, and Preliminary Instrumentation

Kevin, Brian, and I installed a reverse osmosis filtration system, an irrigation line, an electrical line, and several data instruments/loggers. This included pounding a 7-foot copper grounding rod into the ground. The filtration system is used to change the chemistry of local tap water to resemble that of rainfall for our experiment. Sunny weather, with …

Hoop-House at Coweeta

Construction on the soil model at Coweeta Hydrologic Laboratory has begun! We will be using the model for a water and nutrient reaction and transport experiment to answer questions, such as: What is the dominant process (e.g., biogeochemical or hydrologic) for controlling export of nutrients from a hillslope? Under what conditions can we expect these controls …
