Provenance & quality
The water resource systems model has been built with the Water Evaluation And Planning system (WEAP, https://www.weap21.org/). Data from varied sources has been processed to characterise the Sutlej-Beas system in a semi-lumped spatial distribution, e.g. land cover and soil data, technical information about infrastructures and uses of water. The climate data for the baseline has been generated by spatially aggregating the high resolution outputs of the Weather Research and Forecasting model developed by the British Antarctic Survey for the Himalayan zones of the Sutlej-Beas system (partially published in https://doi.org/10.5285/74fab393-2718-4bdb-b229-190ae72a9fe1) and data from the Coordinated Regional Downscaling Experiment (CORDEX) for the downstream plains. All these data is embedded in the WEAP model files.
The future climate data has been generated applying delta changes, calculated with the publicly available data of the Coupled Model Intercomparison Project Phase 5 (CMIP5) in the KNMI Climate Explorer, to the baseline data. The future glacier data has been based on the work by the Divecha Centre of Climate Change (partially published in https://doi.org/10.18520/cs/v116/i10/1721-1730). See https://doi.org/10.1007/s10584-020-02795-2 for more details on the methods to generate future climate and glacier data.
