3-D Water quality simulations in Mornos Reservoir

Abstract

Simulations were performed of the 3-D hydrodynamic circulation and of the associated water quality behavior in Mornos Reservoir, under real environmental conditions, during the period 2003-2005. The water quality simulations, guided by observations taken at the contributing tributaries and at the surface of the Reservoir, generated in-depth profiles of pH, DO, NO3, NH4, TN, TKN, PO4, TP, TOC and of Chl-a, along with surface and indepth horizontal distributions of these quantities, giving an overview of the variation of the Reservoir's water quality. Comparison of plots of the simulated quantities with field data indicates that the Reservoir remains indeed oligotrophic; it also shows the potential of the tools used, and the need for acquiring more systematic "in situ" observations by EYDAP. © 2009 Global NEST.
