This research will examine soil erosion, floodplain sedimentation, and the legacy of medieval agriculture in pluzina landscapes of the Czech Republic. These agricultural landscapes date to the early 14th century and represent a form of centennial time scale soil erosion experiment. The broad goal of this research is to compare high-resolution sedimentological, geochemical, and paleoecological records of soil erosion with spatially-distributed model-based estimates of erosion rates and patterns. The project was initiated during 2014-2015 under a one-year pilot award that supported coordination of an interdisciplinary team of senior personnel and preliminary data acquisition. The current proposal requests three years of support to: 1) establish robust fluvial archives of agriculturally-influenced erosion and sedimentation; 2) quantify agricultural land-use patterns and establish a hydrographically-explicit database for modeling erosion patterns; 3) perform spatially-distributed erosion modeling and compare model results with field-based alluvial stratigraphic records. The research will contribute directly to the development of theory in geomorphology, agricultural legacy sediments, and hillslope-floodplain connectivity. From a broader perspective, the project will transform our understanding of soil erosion over time scales that are critically important for understanding longer-term environmental and agricultural sustainability.
