Track a dissolved pulse in an aquifer. A layered cutaway, screened wells and a concentration ribbon connect transport, spreading and sampling.
• 3D scene parts: Aquifer / confining layers; initial pulse source; concentration ribbon; screened monitoring wells; groundwater flow. • Controls: Initial dissolved mass (1–20 kg); Hydraulic conductivity (1–20 m/day); Hydraulic gradient (0.005–0.05 fraction); Effective porosity (0.2–0.4 fraction); Dispersion coefficient (0.1–2 m²/day); First-order decay (0–0.02 1/day); Sampling distance (0–100 m). • Live readouts: Elapsed process time (day); Plume centroid (m); Standard deviation (m); Well concentration (mg/L). • Guided experiments: No decay; Greater dispersion. • Four tabs (visual laboratory, curves and measurements, experiments, learn and assess), a model-verification run, a timestamped event log and a trial report.

Infinite 1D Gaussian pulse, homogeneous aquifer, no sorption or boundary effects. Starts at process day 1 to avoid a singular initial pulse. Geometry and lateral spread are illustrative. Try the preset experiments, then compare the live readouts with the equations.
Advection moves; dispersion spreads..
