The Caltech Earth Surface Dynamics Laboratory is a 4000 sq. ft. high-bay space designed to facilitate physical experiments and models to study the processes that erode, transport, and deposit sediment on the surface of the Earth and other planets. The lab is located on the main Caltech campus, a short walk from the GPS Division. It includes a state-of-the-art tilting flume (below) to investigate fluvial bedrock erosion, sediment transport in rivers, and initiation of debris flows. The lab also includes a river-plume flume for research into backwater dynamics and delta formation. Please see our Research for examples of past experimental research.
