SUMMARY A new indirect way of producing all‐quad meshes is presented. The method takes advantage a well‐known algorithm the graph theory, namely Blossom algorithm, that computes minimum‐cost perfect matching in polynomial time. Blossom‐Quad compared with standard procedures. Meshes produced by approach are better both terms element shape and size field efficiency. Copyright © 2012 John Wiley & Sons, Ltd.
Connectivity between coral reefs is critical to ensure their resilience and persistence against disturbances. It driven by ocean currents, which often have very complex patterns within reef systems. Only biophysical models that simulate both the fine-scale details of currents life-history traits larvae transported these can help estimate connectivity in large Here we use unstructured-mesh coastal model SLIM locally achieves a spatial resolution ~100 m, 10 times finer than existing models,...
Estimating connectivity between coral reefs is essential to inform reef conservation and restoration. Given the vastness of ecosystems, can only be simulated with biophysical models whose spatial resolution often coarser than scale. Here, we assess impact on estimates by comparing outputs five different setups same model resolutions ranging from 250 m 4 km. We show that increasing around yields more complex less directional dispersal patterns. With a fine-resolution model, graphs have...
In the context of a warming world, annual bleaching events are becoming more likely and threaten coral reefs on global scale, leading to growing interest in identifying local-scale thermal refugia. However such shallow reef refugia predicted disappear +2.0 °C climate world. Yet, hope remains as Northern Red Sea (NRS) corals could act refuge until end century. While being virtually immune change, these so-called ‘super-corals’ not anthropogenic stressors NEOM...
The Suez Canal holds a pivotal role in global navigation and supply chains by facilitating the movement of goods between East West. Around 50 vessels navigate canal daily. However, pressing concern threatens its operational stability: escalating sediment deposition that necessitates frequent dredging. While these sediments originate from diverse sources like land erosion northern Sinai tributaries to canal, significant portion could Nile Delta. This influx results heightened delta,...
Abstract This paper provides a comparison of five finite element pairs for the shallow water equations. We consider continuous, discontinuous and partially formulations that are supposed to provide second‐order spatial accuracy. All them rely on same weak formulation, using Riemann solver evaluate interface integrals. define several asymptotic limit cases equations within their space parameters. The idea is develop these numerical schemes in relevant regimes subcritical flow. Finally, new...
SUMMARY This paper presents multirate explicit time‐stepping schemes for solving partial differential equations with discontinuous Galerkin elements in the framework of Large‐scale marine flows. It addresses variability local stable time steps by gathering mesh appropriate groups. The real challenge is to develop methods exhibiting mass conservation and consistency. Two approaches, based on standard Runge–Kutta methods, are analyzed. They well suited optimized framework. significant speedups...
