Modeling sand mining activities using suction pump on the river/sea by Telemac

Abstract

     Modeling sand mining using suction pump is a problem in numerical modeling application. Previous studies modeled sand mining on the riverbed using suction pumps and dredging operations which were modeled identically. This approach does not lead to simulate the real-time sand extraction along with the hydrodynamic process and sediment transportation. The objective of this paper is to present a method of modeling sand mining using suction pump in real-time. The research results show that the change of the riverbed is physically consistent, with a very low error of 0.002%. This method can be applied flexibly with sand extraction capacity changing over time and can be similarly applied to the problem of mining site.
