HGS RESEARCH HIGHLIGHT - Integrating hydrological modelling, data assimilation and cloud computing for real-time management of water resources
Online data acquisition, data assimilation and integrated hydrological modelling have become more and more important in hydrological science. In this study, we explore cloud computing for integrating field data acquisition and stochastic, physically-based hydrological modelling in a data assimilation and optimisation framework as a service to water resources management. For this purpose, we developed an ensemble Kalman filter-based data assimilation system for the integrated hydrological model HydroGeoSphere, which is able to run in a cloud computing environment.
HGS Research Highlight - Topographic control on groundwater salinization due to ocean surge inundation
Ocean surges introduce saltwater to coastal aquifers and threaten fresh groundwater resources. Topography controls the spatial and temporal dynamics of surge inundation processes, which leads to variable depths of saltwater inundation and heterogeneous infiltration. Our study explored the impact of coastal landforms (e.g. ponds, dunes, barrier island, and channels) by simulating surface water flow over synthetic and real-world topographies, and associated subsurface flow to systematically assess the impact on surge-introduced salinization of coastal aquifers...
