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 …

1000th water sample

Last week on our Hydropedology Project, Scott collected the 1000th water sample from watershed 3 at Hubbard Brook. This is quite a milestone!

3 more weeks to apply for summer REU position in New Hampshire

Applications for the Hubbard Brook Research Experience for Undergraduates (REU) Program are due by February 6 – that’s just 3 weeks away!  We are seeking a student to work on a hillslope hydrology project looking at how water travels through soils on its way to streams in forested ecosystems.  See our post from Dec. 11th …
