A Better Tropospheric Aerosol Analysis and Forecast Using Data Assimilation and Coupled Modeling
… and ozone. This dissertation incorporated a coupled model between meteorology and air quality, as well as data assimilation techniques to get more complexity and reliability of chemical transport models. In the first chapter, we assimilated the GOCI AOD into the WRF-CMAQ two-way coupled model …

Modeled sensitivity of the northwestern Pacific upper-ocean responses to tropical cyclones in a fully coupled climate model with varying ocean grid resolution
… interactions are largely unexplored in fully-coupled models. Here we analyze the upper-ocean response to TCs using a high resolution Earth system model, in which a 0.5° atmosphere is coupled to an ocean with two different horizontal resolutions: 1° and 0.1°. The model produces realistic TCs up …

Numerical Simulation of the Propagation of Fine-Grained Sediment Pulses in Alluvial Rivers
… a component intended to improve the numerical modeling of morphodynamic processes in alluvial sand-bed rivers by proposing a novel solution methodology that applies either the decoupled or the coupled modeling approach based on local flow and sediment transport conditions. Secondly, a detailed …

Coupled Sediment Yield And Sediment Transport Model To Support Navigation Planning In Northeast Brazil
… More recently, hydraulic and sediment transport modeling techniques have been developed and applied in designs of specific waterway development features within discrete reaches of a system. However, previous large scale waterway development planning has not incorporated both the sediment yield …

Seasonal hydrologic dynamics under changing climate, land use-land cover and human influence
… to global scale. Aided by satellite data, modeling and understanding of the interactions between physical and human systems, more reliable regional LULCC and climate change projections are now available. However, resulting quantitative projection of changes on the hydrologic components at …

Coupled Air-Sea-Land Interactions: Understanding the MJO Eastward Propagation and Maritime Continent Barrier Effect
… has been the subject of many observational and modeling studies, it remains a challenging phenomenon for both theoretical understanding and accurate prediction in global weather and climate models. The overarching goal of this dissertation is to better understand the physical processes affecting …

Application of the Variational Fracture Model to Hydraulic Fracturing in Poroelastic Media
… and reservoir. In this dissertation, a fully coupled hydraulic fracturing simulator is developed by coupling reservoir-fracture flow models with a mechanical model for reservoir deformation. Reservoir-fracture deformation is modeled using the variational fracture model which provides a unified …
