My research program examines various aspects of erosion and sedimentation primarily in fluvial systems through the use of experimentation, theory, field studies, and numerical modeling. The overall goals of the research are to quantify flow and sediment transport processes using an interdisciplinary approach and to determine the impact of these processes on river form and function, water quality and ecology, landscape evolution, and watershed infrastructure and integrity. This work is fundamentally important because sediment is one of the leading causes of water quality impairment nationwide, and soil erosion is the leading cause of soil degradation worldwide. Excessive sedimentation also reduces the performance of flood-control reservoirs and increases risks to flooding within river corridors. Below is a brief description of these activities, divided into four categories.
