Modelling of a watershed: A distributed parallel application in a grid framework
This work proposes a joint implementation of spatially distributed runoff and soil erosion analysis in watersheds allowing subsequent modelization of nutrients transport processes originating from distributed sources. Implemented relying on the open source GRASS (Geographic Resources Analysis Support System) GIS (Geographical Information System), a new design for the raster operation routines is specially created to take advantage of the MPI possibilities and available GRID resources.
