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...

Post-doctoral research opportunity in quantitative hydrologic science
Assiniboine River Basin – Land use change impact assessment
The successful candidate for this position will spearhead a high-resolution modeling analysis of land-use change influences on the hydrologic characteristics of the Assiniboine River Basin, with specific focus on flood and drought resiliency. As part of the larger Assiniboine River Basin team at Aquanty......
HGS Parallelization - Best Practices
Fully-integrated hydrologic simulations, such as those performed with HydroGeoSphere, involve highly nonlinear processes, and thus the computational efficiency of the model becomes a critical issue for those performing hydrologic simulations. HGS was parallelized by Hwang et al., 2014 to over come this challenge.
The post summarizes how to setup a parallel HGS simulation, as well as some general best practices for running a parallel simulation.
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.
