BetaBetaDataset
To provide data on surface water runoff from river discharge based on climate water balance.
It was one of the first attempts to demonstrate the potential of combining observed river discharge information with a climate-driven water balance model in order to develop composite runoff fields which are consistent with observed discharges.
Dataset consists of observed runoff and annual runoff in millimetres per year.
Selected gauging stations from the GRDC data archive were co-registered to a simulated topological network (STN-30p) developed at the University of New Hampshire (UNH). Regions between gauging stations (inter-station regions) 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. Correction coefficients based on the ratio of observed and simulated runoff at inter-station areas were calculated and applied against simulated runoff to create composite runoff fields.
