RISC-KIT's Deliverable 3.2 "Updated Physical models" is now ready and available

Deliverable 3.2, entitled "Updated Physical models" represents the work done on the improvement of the formulation of physical processes in three well-known models

RISC-KIT Deliverable 3.2 is now available! The work aims to the update the physical formulations of several well known models, to be added to RISC-KIT's tool-kit in order to provide solutions towards increased coastal resilience. The deliverable consists of a validation document and description of the new developments of the XBeach model, the description of the numerical formulation for storm wave energy dissipation implemented in SWAN, and the description of the improved flash flood module and its integration in the Coastal FEWS platform.

 

In the framework of the WP3 of RISC-KIT, XBeach has been further developed to improve the computational speed of the model as well as the physical descriptions to enhance the accuracy and reliability of the simulations. This included improving the MPI parallel implementation, implementing cyclic lateral boundary conditions, improving the efficiency of directional wave energy propagation, and developing a morphological non-hydrostatic model. The developments were validated and tested for field situations and engineering applications.

 

In the second part, a new formulation for estimating the wave energy dissipation over vegetation in coastal areas is implemented in SWAN model and validated against flume tests and field measurements.

 

Finally, the flash flood model developed in the FP7 project IMPRINTS was improved by increasing the resolution and better estimation of the hazard level. The improved model was applied successfully on the Tordera Delta in Spain, a RISC-KIT case study site, and an implementation recipe is now made available.

 

The flash flood hazard assessment products are displayable in the free-ware Coastal FEWS system which is developed as part of Work Package 3 of RISC-KIT (Deliverable 3.1). The improved physic based models and new developments (codes) delivered in this task are made available through the open source and free software community web portal, and will be used in case study sites in the WP5 of RISC-KIT Project.
