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.
HGS Research Highlight - Coupled atmospheric, land surface, and subsurface modeling: Exploring water and energy feedbacks in three-dimensions
This post highlights the recent study by Davison et al. (2015) on the coupling of HGS to an Atmospheric Boundary Layer (ABL) model. Implementing the coupled HGS-ABL model the authors found ...
HGS Research Highlight - A simple iterative method for estimating evapotranspiration with integrated surface/subsurface models
This work presents an iterative, water balance based approach to estimate actual evapotranspiration (ET) with integrated surface/subsurface flow models. Traditionally, groundwater level fluctuation methods have been widely accepted and used for estimating ET and net groundwater recharge; however, in watersheds where interactions between surface and subsurface flow regimes are highly dynamic, the traditional method may be overly simplistic....
