MEFQ simulates the chemical-biological processes present in the bidimensional hydrodynamic systems. The water quality model MEFQ interprets the existing relationships among producers, consumers and decompositors, being influenced from the values assumed by extensive variables like temperature, illumination and aeration. Following the scheme synthetically shown in figure, the dissolved oxygen is furnished to the system by aeration from the interface air-water and from the photosynthetic activity by the primary producers (phitoplancton and phitobentos, etc.), while in considerable measure is consumed for the degradation of the organic substance (BOD) by the work of the decompositors. The nourishing entries (N, P) are used to describe the dynamics of the primary productivity in function of variables like, for example, temperature and illumination.
MEFQ constitutes, together with the dispersive model MfdLag with which is organically integrated, a finite element water quality model. |
