Our riparian hydrogeophysics project has been focused on two streams running through the drained bed of Lake Perez in central Pennsylvania, about 20 minutes from the Penn State campus. The lake was drained about 4 years ago. We have installed on these two reaches over 100 shallow and deep groundwater wells to monitor water table dynamics in response to precipitation events, etc. We have also deployed fiber optic cables to monitor streambed temperatures along these reaches.
In mid-June we hired a geoprobe rig and operator to install ~40 deep wells (relatively deep – 10 ft) at the experimental reach on the main stem of Shavers Cr. We were able to extract ~5 ft cores in this process and we have collected and cataloged those so that we can characterize the stratigraphy of the soils and sediments adjacent to this stream.
We had a lot of help getting this work done and we are very grateful to Erik, Erika, Zach, Emily, Colin, and Ryan for their time, effort, and patience!
