Since 2014, our group has been continuously developing and applying the Coupled Ocean-Atmospheric-Wave and Sediment-Transport (COAWST, Warner et al., 2010) to the Gulf of Mexico waters (Gulf-COAWST). Our model features a 4-km resolution Gulf of Mexico domain, a 1-km resolution Northern Gulf of Mexico domain, and several 200-m resolution domains focusing on estuaries and bays.

Gulf Coawst


Some key features of Gulf-COAWST including:

Wave Supported Fluid Mud


A Wave-Supported-Fluid-Mud module for ROMS (Zang et al., 2020)

Sediment-induced Ligth Attenuation

Coupled Physical-Biogeochemical Model

Light attenuation module introduced by suspended sediment (Zang et al., 2020) 



Full-distributed process-based sediment module for WRF-Hydro with coupling with the ocean model (Yin et al., 2020)


Dissovled Oxygen and N, P, Si cycle

Dissolved Oxygen model

Dissolved oxygen model that incorporates Nitrogen, Phosphate, and Silicate cycles and Machine Learning capability (Ou and Xue, 2022a, b, in review)

Carbon Cycle with Landloss inputs

Ocean carbon cycling Model

Ocean carbon cycling model with dissolved organic matter, formation & dissolution of CaCO3, and land loss input (Zhang and Xue, in review)

Dynamically Coupled Ocean-River Model

Coupled ocean (ROMS) and river (WRF-Hydro) model

Dynamically coupled ocean (ROMS) and river (WRF-Hydro) model (Bao et al., submitted)
