Research

My research is currently focused on the study of hyperpycnal flow deposits in the Northern Santa Barbara Channel. Hyperpycnal flow occurs when the density of fluvial output exceeds the density of the body of water it drains into, resulting in a flow that hugs the sea-floor and bypasses the littoral cell. Multiple fans can be seen directly offshore from several small creeks draining into the Santa Barbara Channel from the Santa Ynez Mountains. During large flooding events, these creeks can carry enormous amounts of suspended sediment and bedload material, which leads to formation of a hyperpycnal plume. These fans are the first example of hyperpycnal deposition in an active margin basin and a study of their composition, morphology, and depositional processes will lead to a greater understanding of coastal sediment transport mechanisms.
