Abstract

Sensitivity analysis applied to a water quality model for dissolved oxygen. Application to an irrigation channel in a Valencian community, Spain P.A. Lopez & V. Espert Fluid Mechanics Group, Department of Hydraulic and Environmental Engineering, Polytechnic University of Valencia, Spain. Abstract This paper presents the sensitivity analysis developed with a mathematical model for Dissolved Oxygen over an irrigation channel in Valencian Community, Spain. This channel transports water from agricultural irrigation, waste water and industrial discharges, and the processes of dispersion, transport and interaction between the water constituents have been studied. The Dissolved Oxygen (DO) model, developed in finite differences, integrates the Nitrogen cycle and the BOD study within the DO equations. As a result, we can evaluate the concentration of every constituent in the system. We can make also an estimation of the influence of each parameter in the comparis
