Dr. Joel Johnson's research focuses on quantifying active surface processes on hillslopes and in fluvial channels, in order to relate active surface processes to the evolution of topography over both short and long timescales. Common themes include understanding feedbacks in complex geomorphic systems, interpreting relationships between landscape process and form, and separating signatures of external forcing from internal system dynamics. Research topics include quantifying how climate gradients and bedrock properties influence topographic development, understanding controls on tsunami and storm surge deposition, and constraining feedbacks between sediment transport rates, sediment sorting and the evolution of bed roughness in mountain rivers.
