Capacity building projects in Asia, Africa and the Americas

Our department is involved in a number of capacity building projects outside Europe in countries like Cuba, Myanmar, Mozambique and Vietnam. These projects have been interesting and useful for our own development of open source software.

The main sponsor for these projects are the Norwegian Agency for Development Cooperation (NORAD - www.norad.no). We have had a particularly close collaboration with colleagues at the National Center for Hydro-Meteorological forecasting in Vietnam (nchmf.gov.vn ) since 2012. The main activities in this collaboration have been model verification, storm surge modeling using ROMS ocean model (www.myroms.org ), ocean trajectory modeling using OpenDrift (opendrift.github.io ) and satellite observations of wave height using WAVY (github.com/bohlinger/wavy ). OpenDrift is used for oil spill, search and rescue and lately also for marine plastic simulations.

 

Figure 1: Example of 30 day OpenDrift simulation of marine plastic near the Mekong river delta, forced by high resolution ROMS ocean model with (blue) and without (green) river input. The simulation is carried out by master student Nguyễn Mạnh Dũng at the University in Bergen.
