The method applied in the preparation of this data set utilizes a gridded river network at 30-minute spatial resolution to represent the riverine flow pathways and to link the continental land mass to oceans through river channels. Selected gauging stations from the Global Runoff Data Centre data archive were co-registered to a simulated topological network (STN-30p) developed at the University of New Hampshire. Inter-station regions between gauging stations along the STN-30p network were identified. Inter-station discharge and runoff were calculated to compare observed runoff with outputs from the water balance model (WBM) simulation.

Supporting Documentation:
This documentation contains intermediate data sets, such as attributes and long-term monthly regimes of the selected gauging stations. Also included are the simulated topological network (STN-30p) and STN-30p derived attributes for the selected stations and gridded filed of the inter-station regions along STN_30p.
