FUTURE FLOOD HYDROLOGY 28

By4.1 GBM Basin Model Development

Given the importance of flooding to overall agriculture production, special effort was made to model the future flood hydrology under various climate change scenarios for the flood monsoon months (i.e. May-September). To do this, three sequential steps are taken: (1) a sub-set of climate change scenarios are selected; (2) flows into Bangladesh are generated using a Ganges-Brahmaputra-Meghna (GBM) river basin model; and (3) hydrologic changes within the country are generated using a national river network model.
