Hassan's work on observation-constrained projections of record event occurrence in Pakistan has been accepted for Environmental Research Letters. In his work, the multiple AI models  generated multiple ensemable projections of high and low record events in annual maximum and minimum streamflow, respectively, over four major upstream river basins in Pakistan. He also proposed a method for the selection of the optimized ensemble member size through the Principal Component Analysis. He found that more record/unprecedented high and low flow events in Pakistan.

Dr. Wang Dagang  is a co-author of his paper. Here is a reference of Hassan's paper:

Dr Kim's work on streamflow reconstruction and hydrologic forecasting for Bangladesh is accepted in Scientific Data. This reconstructed data is at 10-km resoltuion over the Ganges-Brahmaputra-Meghna River Basins in Bangladesh (1951-2023). The reconstructed streamflow and hydrologic forecasts are generated by the VIC-River Routing model simulations foreced by the ERA5 Land reanalysis and S2S forecast data.
