Abstract
The assessment of catchment behaviour is a complex issue and constitutes a
valuable tool for water resources management. The aim of this paper is to present
the theoretical basis of MODCEL, an integrated program for river basin
simulation composed by three different models that perform hydrodynamic,
hydrologic and water quality simulation, also allowing representation of water
users’ withdrawal, wastewater discharge and operation of hydraulic structures.
The main engine of MODCEL is based on a hydrodynamic cell model. This
hydrodynamic model represents the basin through a cell network in order to
produce a looped discharge net to simulate flow patterns. The hydrologic model
performs rainfall-runoff simulation and works as a lumped model in each cell of
the domain region, although it can be variable from cell to cell. The water quality
model is based on a lagrangean approach and applies for the transport of
particles that represent conservative or nonconservative substances. The
developed program can be used in many different applications, such as
rainfall-runoff simulation and flood routing, among others. Finally, a case study
applied to the Paraiba do Sul river basin in Brazil is presented.
Keywords: cell model, hydrologic modelling, river basin simulation.
1 Introduction
Water resources management depends on the assessment of quantitative and
qualitative issues regarding river basins. In this context, mathematical models
can provide an important support tool for this analysis.
MODCEL is a computer program developed for river basin simulation. It is
composed by three models which are responsible for hydrodynamic, hydrologic
