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.
Webinar - Introduction to Integrated Hydrologic Modelling with HydroGeoSphere
We recently recorded a webinar for the National Centre for Groundwater Research and Training (NCGRT) in Australia titled: "Introduction to Integrated Hydrologic Modelling with HydroGeoSphere" presented by Dr. Ed Sudicky and Dr. Steven Frey.
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....
HGS Research Highlight - An exploration of coupled surface-subsurface solute transport in a fully integrated catchment model
Coupling surface and subsurface water flow is one of the strengths of fully integrated hydrological codes such as HydroGeoSphere (HGS). Following the coupling of surface-subsurface water flow, is coupling of surface-subsurface solute transport, although this subject has received less attention in the literature. ...
HGS Research Highlight - Holding and Allen 2015
Wave overwash events (such as storm surge and tsunamis) have the potential to result in severe consequences to the freshwater resources of small islands as a result of salt contamination of the aquifer. This study used numerical modelling to evaluate the freshwater lens response and recovery to overwash events for various island hydrogeological settings - or island types - that are observed worldwide
Changes to HGS Licensing and Distribution
We have recently changed the name of our HydroGeoSphere distribution from HGS 2013 to HGS Premium. With this comes a number of other changes that we believe will better suit our user’s needs. Some of the major changes include:
