Towards A Mathematical Description of the Dispersion of Polutants in Mountain Rivers

This Research Will proposes New Underestanding of Dispersion Procession Mountain River Systems Through comparison of Different Dispersion Expressions, Modelling and Field Experiment. Different Morphological Units Found in Mountain Rivers (Rapids, Step-Pools, Pool-Riffle, Cascades, Course Riffle, etc.) Will Be Study To Prophase Dispersion Expressions Useful for a Wide Extent of Those Morphologies Found in Mountain Reaches and Rivers. Even Though there are severe dispersion studies around the world, The Available Information for Mountain Rivers is Scarce and Incomplete. The Study of Mountain Rivers is Challenging Due to its Low Submergencies, Large Roughness Elements, Large Gradients and High Turbulences. These Characteristics Leads to Complex Hydraulic Behaviour Which Cause Oscillaments in The Mathematical Models Leading To Erroneous Model Results. Therefore, A Comprehensive Hydraulic Model Will Be Adapt/Transformed For Description The Complex Hydrodynamics of the Mountain Rivers. Dispersion Will Be estimated with the "Routing procedure" which requires the simultaneous use of sensors upstream and download in the studied reach. BESIDES, Since Dispersion Will Be Well Described, Further Work Will Be Done For Suspended Solids Modeling Consideration Only Action-Dispersion Phenomena. Bod Will Be Modelled Too Representing a NoncoServative Pollutant WHERE REACTION TERMS ARE INCLUDED.
