Analog Channel-Shape Model.
I’m painting the model black because the sand is a light brown. It will help me see and document the results. The flow will be controlled with a small filter fountain pump placed in the end basin (which in reality would be the “Cuatro Bocas” turning basin, just past the Riachuelo and squarely in the Port Dock Sud facilities). The water will be pushed through a 1/2” inside diameter vinyl tube. I wanted the biggest one possible to approximate a slow, even flow of the kind in the Riachuelo (as opposed to the same amount of water shooting through a tiny pipe at high velocity).
The design goal for the sediment aspect of the project is to design a channel-sediment regime that ends up with no sediment in the basin where the pump is. This would suggest that I am trapping all of the sediments of the Riachuelo within the Tierra Plastica project.
The significance of this concentration means a reduction in the total amount and dispersal of contaminated sediments that must be dredged, treated, and confined by the Port- a major value added and hopefully validating the economic expenditure necessitated by the proposed changes.
