HYDRAULIC RESISTANCE INDUCED BY DEPOSITION OF SEDIMENT IN POROUS MEDIUM. TECHNICAL NOTE

This note investigates the deposition of the instantaneously released sediment into a gravel matrix and the hydraulic resistance induced by the rapid siltation. The experimental results reveal that the depositional patterns of the sediment are governed by the gravel-sediment size ratio, the amount of sediment released, and the seepage flowrate. The observations also indicate that the stable stage of sediment deposition is reached shortly after the occurrence of sudden slump. A regression relation is developed to quantify the stable-stage hydraulic resistance with the major governing factors. Given the hydraulic resistance, one can use the siltation equation to evaluate the hydraulic conductivity of the silted porous medium. With such information, planning of the engineering alternatives to meet the seepage flow requirements is made possible.
