Applied Groundwater Modeling Using Visual MODFLOW Flex

Master fundamentals of groundwater systems, including the hydrologic cycle, saturated and unsaturated zones, and aquifer formations. Calculate hydraulic head, piezometric head, and hydraulic gradients to analyze aquifer flow.

Explore key groundwater properties that control aquifer performance, including total and effective porosity, specific yield and retention, specific storage, and the storage and transmissivity concepts for confined and unconfined aquifers.

Derive the groundwater flow and transport equations from Darcy's law and continuity, then explain homogeneous and isotropic vs heterogeneous, and discuss advection, dispersion, diffusion, and sorption.

Explore the principles of groundwater models, including interpretive, predictive, and generic types, and how to build a conceptual and numerical model with calibration and scenario analysis using Visual MODFLOW Flex.

Introduce Visual Modflow Flex and its interface for groundwater modeling. Explore numerical and conceptual workflows, including grid design, hydraulic conductivity, storage, boundary conditions, and result visualization.

Design and run a visual Modflow flex groundwater model for a three-layer unconfined aquifer, define grids and boundary conditions, and perform steady state and transient simulations with particle tracking.

Build a Visual MODFLOW Flex groundwater flow and transport model for an industrial site with a 300mg/l plume, using three 62 m3/d remediation wells to capture the plume.

Develop a conceptual groundwater model in Visual MODFLOW Flex by importing data, creating horizons, setting boundary conditions (river, constant heads, pumping wells), and translating to a numerical grid.

Conduct steady-state and transient groundwater flow analyses of an unconfined coarse-grained aquifer using Visual MODFLOW Flex, incorporating recharge, pumping, and boundary conditions to predict water levels.

Explore creating and calibrating a groundwater model in visual modflow flex, featuring four stress periods, zone-based hydraulic conductivity, observation wells, pumping wells, and boundary conditions.

Apply paste-based automatic calibration in Visual MODFLOW Flex by defining observations, pilot points, and kriging variograms to optimize hydraulic parameters and improve model fit.
