Seasonal streamflow hindcast data for the Upper Segura and Upper Tagus river basins
Description
The datasets provided here have been produced as part of the IMPREX project for work package 11, task 2. The aim was to evaluate the performance of climate model-based seasonal hydrological forecasting system that is used to predict drought indices of the Segura River Basin and the Tajo-Segura Water transfer System. These indices rely on forecasted discharge values and describe the expected status of the water availability in both systems. Also, for the Tagus basin, the forecasts can be used to determine the amount of water transferred to the Segura river basin. The key involved stakeholder is the River Basin Authority of the Segura Basin that uses these drought indices for drought mitigation actions. This task developed and evaluated a forecasting system for these drought indices.
The dataset - Pseudo_Obs_SPHY_Spain02_Output.csv include streamflow simulations for the Entrepenas and Buendia discharge stations located in the Upper Tagus basin, Spain in addition to the Fuensanta and Cenajo discharge stations located in the Segura river basin, Spain. Hydrological outputs are produced using The Spatial Processes in Hydrology (SPHY) model (Terink et al., 2015) forced by the Spain02 V4 meteorological dataset (Herrera et al., 2016) for the period 1979-2010. Please note however that there are known issues with the Spain02 dataset for the years 2007-2010 that affect this dataset.
The dataset - SPHY_ECMWF_S5_Output.csv includes streamflow simulations for the same locations using the SPHY model albeit forced with the ECMWF SEAS5 hindcast data for the period 1981-2010. The column “LD” represents lead month where the first month of hindcasts is signaled as 1, second as 2 and third as 3. The “Ens” column refers to the individual ensemble members as 25 in total are used for this setup.
