This workshop consists of two main programs related to HydroGeoSphere (HGS): two-day short course for beginners and three-day advanced workshop for graduate students and researchers.
The short course starting from June 27th to 28th covers the development of integrated hydrologic models using HydroGeoSphere (HGS). The HGS model is a three-dimensional groundwater-surface water flow and contaminant transport model and has been used in various fields from hydrologic studies to engineering applications. Participants will learn how to apply HGS to their own research or industrial projects through a combination of presentations and hand-on practices. The topics covered include: theoretical background of groundwater-surface water flow and contaminant transport (mathematical formulation and numerical approaches); hands-on simulation exercises (data preparation, mesh generation, HGS operation, calibration, visualization, and result interpretation); cost-effective computing skills (parallel computing utilities, characteristics of nonlinear problems, and effective mesh generation).
The advanced workshop (June 29th to July 1st) provides details of an integrated surface-subsurface model of the Geum River Basin (GRB) based on a research paper entitled “Estimating Anthropogenic Effects on a Highly-Controlled Basin with an Integrated Surface-Subsurface Model” and its supply data (Hwang et al., 2021). Overall, participants will learn how to generate high-quality meshes, to build an integrated surface-subsurface model, and to operate HGS-PEST program for the model calibrations. Specifically, the topics of this workshop include: 1) overview of a basin-scale model and data structures, 2) detailed mesh generation, 3) 3D subsurface and 2D surface model constructions, 4) simulation parameter settings for cost-effective modelling, 5) detailed HGS-PEST operations based on the example model, 6) groundwater contribution analysis, and 7) model uncertainty analysis.
