Sculpt a landscape, seed a storm, and watch runoff carve the basin.
Standing water, wet ground, and terrain erosion now share one hydrology loop.

A high-relief basin tuned for fast runoff concentration, sharper channels, and visible incision under repeated storm input.
Look for narrow drainage paths, deeper cuts, and strong sediment motion before the basin fully saturates.
