Learn by dragging things

Simulations

Every difficult idea in Research Atlas becomes something you can drag, click, or watch move. These are standalone — no mission progress required.

Darcy's Law Visualizer

Adjust hydraulic conductivity and gradient to see how fast groundwater moves through Bluewater Basin's aquifer, and watch q = K·(dh/dl) update live.

Fit a line to rainfall vs. streamflow data from the Bluewater River gauge. Drag the slope away from the OLS best fit and watch R² drop.

Click anywhere on the basin and trace exactly where a raindrop landing there would flow, cell by cell, to the outlet.

Drag an elevation threshold to draw your own contour line across the basin's terrain — see exactly what a contour line traces.

Adjust skewness and sample size to see how Bluewater Basin's nitrate distribution changes — and when the mean diverges from the median.

Toggle trend, seasonal, and residual layers on the Bluewater Basin nitrate time series to see what each component contributes to the signal.

Explore Bluewater Basin nitrate, dissolved oxygen, and conductivity mapped across all fifteen monitoring wells.

Grow trees one at a time and watch the ensemble vote on flood risk. See feature importance stabilise as the forest grows.

Fit nugget, sill, and range parameters to the experimental semivariogram computed from Bluewater Basin's fifteen monitoring wells.

Adjust the influence range and distance power to interpolate nitrate concentrations between wells. Hover each well to see its influence radius.

Adjust lag time, peak magnitude, and baseflow to see how Bluewater River responds to three rainfall events over 72 hours.

Blend a flexible data-only curve with Darcy's Law's monotonic drawdown constraint, and watch physically impossible fits disappear.

Bootstrap the rainfall-streamflow regression and watch the honest prediction interval emerge from an ensemble of resampled fits.
