MODELING OF THE FLOWS AND SOLID TRANSPORT IN THE CATCHMENT AREA OF MESKIANA- MELLEGUE UPSTREAM (NORTHEASTERN ALGERIA)

Moufida BELLOULA, Hadda DRIDI

ABSTRACT: This article focuses on the study of flows and sediment transport in suspension, according to a probabilistic model flow/Erosion that is the most important modeling point. Furthermore the absence of direct measurements on erosion for experimental stations, on based on operation data from instantaneous sampling liquid fluxes and concentrations of sediment transported during periods of flooding. In this regard a methodology to develop a mathematical model of specific erosion occurs in Meskiana - Mellegue upstream watershed which is part of the great watershed of the Medjerda river (northeastern Algeria). It is home to areas vulnerable to erosion the irregularity of precipitation and their intensity, also the remarkable influence of climatic and topographical factors on particle detachment which mean the outbreak of the erosion dynamics in the basin watershed.
