<!--!introduction!--> A better knowledge of sediment flux to the ocean has many implications for understanding past and future cryosphere evolution including understanding potential impacts on ice shelf stability and ocean circulation, understanding the record of past cryosphere events from sediment records and understanding impacts on nutrient supply and CO 2 drawdown. Physical model studies of subglacial sediment transport are relatively few, and due to computational expense, these often do not explore the broader model space for the glacial scenario of interest. The lack of a comprehensive quantitative knowledge of the subglacial sediment transport system limits our ability to understand sedimentary records of ice sheet change, and to express the potential impacts of future cryosphere change on the ocean. I present here a graph analysis approach to enable broad exploration of model space to understand hydrological change and for quantitative estimates of water and sediment fluxes through the system ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
