Outlook:MESH/RIVICE coupling for Peace River
Description of RIVICE General
a) one-dimensional hydrodynamicsb) implicit finite-difference simulationc) includes optional water temperature simulationd) considers major ice phenomena and processes
Ice processesa) ice cover formation and ablationb) frazil ice formationc) border ice advancementd) anchor icee) ice transportf) hanging damsg) ice jams

Near real-time Ice-Related Flood Hazard Assessment (RIFHA) improve decision making for disaster management and
emergency response within the context of river ice-related flooding.
combine a) satellite-based river ice monitoring, b) in-situ observations and c) hydro-dynamic river ice modelling
to build novel capacity for generation and delivery of near real-time ice-related flood risk assessment info.
