The paper illustrates the development of a hydrodynamic water quality model for the lagoon of Venice, VELFEEM, which is a site specific implementation of a generic water quality transport model, FEEM, obtained by coupling a finite element hydrodynamic model and a standard water quality model. The water quality module is based on EUTRO, the generic code released by US-EPA, but has been improved by adding zooplankton dynamic and properly selecting the values of the kinetic constants. In its present form the model simulates the evolution of phyotplankton, zooplankton, nutrients (phosporus, nitrogen, amonnia) detritus, BOD and dissolved oxygen. The transport model is based on a advective-diffusion two-dimensional hydrodynamic model, which uses a finite element discretization of the basin, so allowing variable resolution and a good trade off between computational demand and need for high resolution. The model has been used to analyze ecosystem response in climatological condition, to begin with, and then to compare the effects induced by different scenarios of external forcing, such as modification in the total nutrient load input from the river basin, modification in the wind regime, modification in the exchange with the Adriatic Sea through the inlets.
