Abstract

In this study a porous obstacle was used to evaluate the performance of permeable obstacles for control of turbidity current. To build mathematical obstacle porous strata of 2.1 * 2.1 cm was used. 10 m long steep flume experiments are conducted. Tests were conducted in a double-dip 0 and 2.5 percent. Discharge constant in all tests was 0.7 liters per second. Feed concentration of 20 grams per liter of the concentrated flow and viscous flow in the upstream and downstream concentrations were measured porous barrier. Concentration was measured with use of a sampler flushing. The results showed that the porous barrier stepped porous barrier to the flow is better. Porous barrier stair staircase behind a thick flow of porous barrier and prevents over-stepped the stairs to the amount of sediment discharge reduced more.
