Concept Lessons.
The foundational physics, one idea at a time — flow, pumping, contamination, remediation, and surface-water exchange. Groundwater is the hardest water science to teach because the system is invisible; these lessons make it visible. Pose a question, run the model, and watch the aquifer answer.
0 clipsTransport Processes
The four engines of contaminant fate — advection, dispersion, sorption, and decay — isolated one at a time.
Open lesson →
0 clipsAquifer Response To Pumping
Cones of depression, well interference, and how transmissivity and storage shape an aquifer’s response to pumping.
Open lesson →
0 clipsGroundwater Contamination
How plumes form, spread, and reach wells — sources, pathways, and the journey from spill to receptor.
Open lesson →
0 clipsGroundwater Remediation
Pump-and-treat, capture zones, and reactive barriers — and why heterogeneity makes cleanup slow.
Open lesson →
0 clipsConnection With Surface Water
Streams, lakes, and aquifers as one system — gaining and losing reaches and the exchange between them.
Open lesson →
0 clipsStream Aquifer Interaction
How conductivity, storage, and stream penetration control the exchange between a stream and its aquifer.
Open lesson →
0 clipsWellhead Delineation
Capture zones and time-of-travel — delineating the land area that drains to a drinking-water well.
Open lesson →
0 clipsRegional Vertical Circulation
Topography-driven flow — local, intermediate, and regional cells, recharge and discharge zones, stagnation points.
Open lesson →
0 clipsLaw Of Refraction
Flow bends at conductivity contrasts — the tangent law, and why water runs along high-K layers and across confining beds.
Open lesson →
0 clipsSeepage Under Dams
Flow nets, uplift, exit gradients, and piping — and how sheet piles control seepage beneath a dam.
Open lesson →
0 clipsArtificial Recharge
Banking water underground — injection, storage, and recovery, and what controls recovery efficiency.
Open lesson →From watching to doing.
