Vision

The vision of CRC is to advance research, enrich training, inspire collaboration, and inform decision making through highly available innovation-enabling CI, with a particular focus on geosciences and engineering integrated with ecosystem ecology for the sustainability of deltaic coasts. We propose an integrated, coupled modeling framework built on top of cloud computing technology tailored for the coastal modeling community. Its primary focus is to facilitate the deployment of complex models on cloud and cloud-like architectures with negligible performance overhead.

CRC CI Architecture

CaFunwave / CHEMORA

CHEMORA is an NSF-funded EAGER project (ACI-1265449) designed to automatically optimize stencil computations for GPUs. CHEMORA will be used to speed up CaFunwave, a module developed for the Cactus Computational Toolkit (a general purpose problem solving environment for scientists and engineers). CaFunwave is based on the Boussinesq equations, which are used to simulate nonlinear waves in the nearshore. These equations have been a useful tool for modeling surface waves from the deep water to the swash zone. CaFunwave implements these equations using the numerical methods and basic grid structure (i.e. grids consisting of logical blocks) of the open-source Funwave-TVD code. CaFunwave, however, has been extended to include the effects of vegetation for modeling surface waves over inundated wetlands and hurricane wind effects for simulating combined waves and storm surge, and to include levees using the Immersed Boundary Method. The continued development of CaFunwave will provide a new tool for the modeling of coastal flood hazards and the design of green infrastructure.

Science Drivers

Multiple-scale Study of Sediment Porcesses in Deltaic Shallow Environment

Mesoscale and regional models like Delft3D and COAWST require local parameterization for unresolved processes that can be complicated and understudied for muddy deltaic sediments. We will implement a coupled boundary layer dynamics-sediment model for shallow environments in the framework of SIMULOCEAN for the easy job execution and solution visualization. The coupled modeling framework is intended to improve the representation of two critical unresolved processes including sediment resupension and mixing in CRC models (COAWST and DElft3D).

The Coupled Ocean-Atmosphere-Wave and Sediment Transpot Modeling Platform

Delta morphology is strongly influenced by interacting waves, currents, and river flow, and these factors must be incorporated into delta conservation/restoration strategies. We will utilize CRC cyber tools to investigate the geomorphological response of two deltaic systems (with contrasting mean wave-current forcing) to tropical cyclones and compare our finding to other CRC models (e.g. CaFunwave, SWAN, and Delft3D).
