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...
HGS Research Highlight - Solute transport processes in flow-event-driven stream–aquifer interaction
This post features a recent study by Xie et al., 2016, who used HydroGeoSphere to investigate the interaction between streams and groundwater controls on key features of stream hydrographs and chemographs.
HGS Research Highlight - Dual permeability modeling of tile drain management influences on hydrology and nutrient transport in macroporous soil
This post features a recent study by Frey et al., 2016 who used 2-dimensional dual permeability HydroGeoSphere models to simulate the flow and transport of liquid swine manure and rhodamine tracer application on a macroporous clay loam under controlled (CD) and free drainage (FD) tile management.
