Sand Dredging: Slurry Transport & Critical Velocity (2D)

2D cutter-suction dredge lab: adjust pump flow, pipe diameter, particle size and cutter concentration to see the Durand critical (limit-deposit) velocity, slurry density and production rate respond in real time.

This 2D companion shows the hydraulic-transport physics that decides whether a cutter-suction dredge actually delivers sand: pump flow and pipe diameter set the slurry velocity, particle size and cutter concentration set what that velocity has to overcome, and the Durand critical-velocity margin between them drives both the readout panel and the flowing particles you can watch stall and settle when the pipeline falls behind.

⚙ Under the hood

2D cutter-suction dredge lab computing the Durand limit-deposit (critical) velocity from pipe diameter and particle size, comparing it live against the actual slurry velocity from pump flow, and animating particles that visibly settle out when transport falls below that threshold.
