Coastal Geomorphology

Coastal geomorphology investigates the processes that shape coastlines and the resulting landforms. Researchers in this area examine how waves, tides, currents, and sediment transport interact to create and modify features such as beaches, dunes, deltas, and cliffs. Studies employ field observations, remote sensing technologies, and numerical modeling to understand shoreline dynamics, sea-level change impacts, and the evolution of coastal environments over geological timescales. Specific research interests include sediment provenance, coastal erosion and accretion rates, and the influence of human activities on coastal systems.

While Arkansas is a landlocked state, the principles of coastal geomorphology are relevant to understanding riverine systems and the management of large inland water bodies, such as the Mississippi River and its tributaries, which are vital to the state's economy and ecology. Research can inform strategies for managing riverbank erosion, maintaining navigation channels, and protecting aquatic habitats within these extensive river systems. Understanding sediment dynamics in large rivers is crucial for agriculture, transportation, and flood control across Arkansas.

This field draws upon and contributes to geological and geochemical analysis, detrital zircon geochronology, and remote sensing technology. Expertise in coastal geomorphology can also inform environmental monitoring and shoreline dynamics studies within Arkansas's significant inland water resources.
