Students watch MAGNET4WATER animations to explore how groundwater flow modeling defines Wellhead Protection Areas (WHPAs). They answer questions about WHPA concepts, protection programs, required data, and strategic uses of TOT maps for safeguarding drinking water, designing monitoring networks, and guiding land use planning. Develop a IGW-NET model to reproduce animations, taking advantage of IGW-NET's realtime interactive visualization and forward and reverse particle tracking capability.

​The time required for a particle of water to move in the saturated zone from a specific point to a well is the Time of Travel (TOT). A line can be drawn around the area for which groundwater is expected to reach the well within a chosen period. Watch the related video, answer short questions, and re-create the animation/model using IGW-NET.

Intermediate - Analytical and numerical sub-problems. A number of techniques exist for removing or greatly reducing groundwater contamination. One method commonly practiced is hydrodynamic isolation or passive plume capture. An extraction well positioned downgradient of the leading edge of the plume will help to stabilize the position of the plume, allowing the contaminated water to then be pumped out of the aquifer. Contaminated groundwater is sometimes treated before disposal or discharge back to the environment.

Application of the particle tracking technique for the delineation of capture zones can sometimes be misleading - because it is only based on advection and does not take into consideration transport parameters, such as dispersion, diffusion, absorption etc. Watch the related videos, answer short questions, and re-create the animations/models using IGW-NET.

Capture zones of wells play an important role in groundwater protection. However, the shape and size of a catchment zone cannot be determined exactly due to inherent heterogeneities/uncertainty of aquifer parameters. Use IGW-NET to probabilistically delineate a well capture zone, taking into account the uncertainty in the aquifer parameters.

A “capture zone” refers to the region that contributes the groundwater extracted by wells or drains. A capture zone in this context is equivalent to the “zone of hydraulic containment”.Given some site-specific information, design an optimum collection system using IGW-NET.
