Fluvial Geomorphology & River Dynamics

The science of river-shaped landscapes — meander migration, stream power erosion, hydraulic geometry scaling, knickpoint retreat in bedrock rivers, and alluvial fan deposition patterns.

Fluvial geomorphology studies how rivers sculpt the Earth's surface through erosion, sediment transport, and deposition. From the sinuous curves of meandering channels to the dramatic headcuts of waterfalls retreating upstream, fluvial processes create some of the most dynamic and recognizable landforms on the planet. Understanding these processes is critical for flood management, habitat restoration, and predicting landscape evolution.

These simulations let you explore meander migration driven by secondary flow, calculate stream power and its erosive potential, examine hydraulic geometry relationships, model knickpoint retreat through bedrock, and visualize alluvial fan formation — all with real-time interactive controls grounded in established geomorphic equations.

5 interactive simulations

simulator

Alluvial Fan Deposition & Morphology

Simulate alluvial fan formation — explore how sediment supply, discharge, and slope control fan radius, gradient, and depositional patterns

simulator

Hydraulic Geometry & Channel Scaling

Simulate hydraulic geometry relationships — explore how discharge controls channel width, depth, and velocity through power-law scaling

simulator

Knickpoint Retreat & Bedrock Incision

Simulate knickpoint retreat — explore how bedrock strength, stream power, and drainage area control the upstream migration of waterfalls and river knickpoints

simulator

Meander Migration & Channel Evolution

Simulate river meander migration — explore how flow velocity, bank erodibility, and channel curvature drive lateral channel movement and oxbow lake formation

simulator

Stream Power & Erosion Potential

Simulate stream power — explore how discharge, channel slope, and width determine a river's erosive capacity and sediment transport potential
