Beryllium-7 has been of recent interest in estimating short-term erosion and sediment fingerprinting (Walling 2012). However, with few exceptions (e.g. Kaste 2011), little is known about vegetation interception or deposition under a tree canopy. As a part of our sediment fingerprinting studies in the Christina River Basin Critical Zone Observatory, we investigate the following questions:
