I investigate these links by integrating numerical modeling, GIS analyses, field techniques (landform mapping, lidar scanning, sample collecting), and lab work (cosmogenic radionuclides, aquatic organism gene flow).
The topographic imprint of climate and tectonics overlaps such that it is difficult to recognize the influence of each. Deconvolving imprints of these drivers can help to explain how mountainous regions evolve, spatial variation of landslides, and how post-orogenic landscapes evolve (Gallen et al., 2011).
The magnitude of landslides is recognizable through detailed field studies and digital topographic data. Identifying the long term drivers of mass wasting can aid susceptibility assessments (Lyons et al., 2014).
The impact of anthropogenic factors upon freshwater mussel distribution is being explored in the Sandhills region of North Carolina. Sand dominates the majority of streambeds, which is not suitable for mussel habitat. On-going work includes mussel surveys, and grain size sampling and modeling in four streams to assess additional contributors to mussel distribution.
Bank erosion was quantified along a stream incising into sediment related to historic land use practices (Starek et al., 2013). We monitored the bank during a 19-month period and a field-based experiment to characterize the processes that deliver this sediment to waterways in the Atlantic Piedmont (Lyons et al., 2015).
