Numerical models show that maximum dike width at oceanic spreading centers should scale with axial lithospheric thickness if the pre-diking horizontal stress is close to the Andersonian normal faulting stress and the stress is fully released in one dike intrusion. Dikes at slow-spreading ridges could be over 5 m wide and maximum dike width should decrease with increasing plate spreading rate. H...

The paper describes concept and implementation details of integrating a finite element module for dike stability analysis “Virtual Dike” into an early warning system for flood protection. The module operates in real-time mode and includes fluid and structural submodels for simulation of porous flow through the dike and for dike stability analysis. Realtime measurements obtained from pore pressu...
